Chapter II: First Development of Forestry Methods (1)

(Period 1500 to 1800.)

The period following the middle ages marks the gradual changes from the feudal system to the modern State organizations and to considerable change of ownership conditions and forest treatment. Various causes which led to an increased development of industrial life were also instrumental in hastening the progress of forest destruction. At the same time, during this period the germs and embryonic beginnings of every branch of forestry, real forestry policy, forestry practice and forestry science are to be noted. By the end of this period, preparatory to more modern conditions, we find organized technical forest administrations, well developed methods of silviculture and systems of forest management.

1. _Development of Forest Property Conditions._

A number of changes in the conceptions of political relations, in methods of life and of political economy brought further changes in property conditions on the same lines as those prevailing in the 14th and 15th centuries. These changes were especially influenced by the spread of Roman law doctrine regarding the rights of the governing classes; by the growth of the cities, favoring industrial development and changing methods of life; by the change from barter to money management, favored by the discovery of America, by other world movements, and by the resulting changes in economic theory.

Through the discovery of the new world and the influx of gold and silver that came with it gave impetus to industry and commerce of the cities; the rapid increase of money capital increased extravagance and induced a desire for amassing wealth, which changed modes of life, changed policies and systems of political economy.

The fiscal policy of the many little principalities was dominated by a desire to get a good balance of trade by fostering exports of manufactures, but forbidding exports of raw materials like forest products, also by forbidding imports, subsidizing industries, fixing prices by law, and taking in general an inimical attitude towards outsiders except in so far as they sent gold and silver into the country.

This so-called mercantilistic system, which saw wealth not in labor and its products but in horded gold and silver, had also full sway in England under Cromwell, and in France under Colbert’s influence. This fiscal policy, which was bent upon bringing cash into the country, led, under the direction of servile officials, to oppressive measures. A reaction naturally followed, when it was pointed out that the real wealth of a nation lies in its natural resources and in its labor. But this so-called physiocratic doctrine had little practical influence except to prepare men’s minds for the reception of the teachings of Adam Smith at the end of the period.

The doctrine of the Roman law, deified by the jurists and commentators, undermined the national conceptions and institutions of free citizenship and of existing property relations; courts, legislation and administration were subject to their sway, and this influence lasted, in spite of reactions, until the end of the 18th century. Under it the doctrine of the _imperium_--the seignorage or superior power of the princes (Hoheitsrecht)--was further developed into the _dominium terrae_, i.e., superior ownership of all the land, which gives rise to the title and the exercise of the function of “_Landesherren_,” masters of the land, and confers the privilege of curtailing and even discontinuing private property rights. To sustain their position in each of the state units, a restriction of the autonomy of churches and cloisters, of the Mark and of the vassals became needful to the princes. This was secured by taking the first under their protection, by making themselves Obermärkers, and by changing vassals who held office in fief into employes (Beamte). For a time the three privileged classes of prelates, knights and burghers, combined in the _Landstand_ or _Landtag_, participated in some of the functions of government, especially in raising and administering taxes, but by the second half of the 14th century the princes had become absolute, and the doctrine of the _Hoheitsrecht_ was firmly established.

Under this doctrine, the historic position of the Mark is perverted and instead of being the common property of the people, it becomes the property of the prince, on which he graciously permits the usufruct; for, forest, pasture and water (Wald, Weide, Wasser) are _res publicae_, hence ownerless and at the disposal of the king. Through this new construction of relationship, as well as through the same machinations and tricks which the princes as _Obermaerker_ or headmen of the Mark had employed during the foregoing period in usurping power, and partly through voluntary dissolution was the decadence of the social, economic and political organization of the Mark gradually completed.

The original usufruct of a property held in common is explained in the Roman sense as a _precarium_ or servitude, and from being a right of the whole organization becomes a right of the single individual or group of individuals. In this way the socialistic basis of the Mark is destroyed. Through the exercise of the _Forsthoheit_, _i.e._, the superior right of the prince over all forest property, by the _appointment_ of the officials instead of their _election_, by issuance of ordinances, in short, by the usurpation of the legislative and police power, the political power of the Mark is broken and the Thirty Years’ War completes the breakdown; the pride of the burgher and the peasant is gone, their autonomy destroyed and their economic and political organizations sink into mere corporations based on land tenure, which, according to Roman doctrine come under the regulation of the State or Prince.

The nobility move into the cities and leave the administration of their estates to officials who are constantly pressed to furnish the means for the extravagant life of their masters. These in turn harass and oppress the peasantry, who finally become bondsmen, _Gutshörige_ (bound to the glebe) and lose their independence entirely. These, briefly, are the steps by which the changes, social and economic, progressed.

Reforms in this situation of the peasantry began first in Prussia in 1702, when bondage was abolished for all those who could purchase their houses and farms from the gentry. As few had the means to do so, the result was the creation of a proletariat, hitherto unknown because under the old feudal system the lord had to feed his impoverished bondsmen from which he was now absolved.

* * * * *

_Changes in forest property_ in particular were brought about by the increase of princely property through the various methods of exercising the seignorage. Especially after the Thirty Years’ War ownerless tracts falling under this right were plentiful. In addition, wherever waste lands grew up to wood, they were claimed by the princes:

“Wenn das Holz dem Ritter reicht an den Sporn
Hat der Bauer sein Recht verlorn.”

When wood has grown up to the spur of the knight, the peasant has lost his right.

Some additions came from the secularization of church and cloister property, and others by the slices which the princes as Obermärker secured from the Mark forests by various artifices. It is these properties, which in Prussia were turned over by the King to the State in 1713, and by other princes, not until the 19th century.

The same means which the princes employed were used by the landed gentry to increase their holdings especially at the expense of the Mark from which in their capacity of Obermärker they secured portions by force or intrigue.

The peasants’ forest property--the Mark forest--had by the 19th century been almost entirely dismembered, part having come into the hands of the princes and barons, part having been divided among the Märker, and part having become corporation forest in the modern sense.

Partition had become desirable when the restrictions of use which were ordered for the good of the forest became unendurable under the rigid rule of appointed officials, but the expected improvement in management which was looked for from partition and private ownership was never realized.

After the Thirty Years’ War the free cities were impoverished and their autonomy undermined by Roman doctrine. From free republics they became mere corporations under the supervision of appointed officials, and experienced decadence in political as well as material directions. Hence, no increase in city forest took place except through division of the Mark forest in which cities had been co-owners, and through secularized properties of cloisters.

The worst feature, from the standpoint of forest treatment, which resulted from these changes in property conditions and relationship, was the growth of the pernicious servitudes or rights of user, which were either conferred to propitiate the powerless but dangerous peasantry, or evolved out of the feudal relations. From the 16th to the 19th centuries these servitudes grew to such an extent that in almost every forest some one outside of the owner had the right to use parts of it, either the pasture, or the litter, or certain classes or sizes of wood.

These rights have proved the greatest impediment to the progress of forestry until most recent times, and only within the last few decades have the majority of them been extinguished by legal process or compromise.

2. _Forest Conditions._

Under the exercise of these various rights and the uncertainty of property conditions, the forest conditions naturally deteriorated continuously until the end of the 18th century; the virgin woods were culled of their wealth and then grew up to brush, as is usual in the United States.

Every forest ordinance began with complaints regarding the increasing forest devastation, and predicted a timber famine in view of the increasing population, increasing industry and commerce, and hence increased wood consumption. Especially along the water routes, which furnished the means of transportation, the available supplies were ruthlessly exploited. More serious enemies than the exploitation of the timber proved the pasturing of cattle, the removal of the litter, and above all, the fires.

Towards the end of the 16th century, ordinances against forest fires began to be enacted; yet, as late as 1778, the necessity of keeping the rides or fire lanes open in the forests of Eastern Prussia is justified by the statement that “otherwise the still constantly recurring fires could not be checked.” At another place it is stated that “not a single acre of forest could be found in the province that had not been burnt in former or later times,” and that “the people are still too much accustomed to the ruthless use of fires, so that no punishment can stop them.”

Other causes of devastation were the Thirty Years’ War, the wars of the 18th century, and the loss of interest in the forest by the peasants after the collapse of the Mark. These had often to steal what they needed, and their depredations were increased by the desire to revenge themselves on the landed proprietors for the oppressions to which they were subjected. The increase in game, which was fostered by the landed gentry, did much damage to the young growths, and the increase in the living expenses of the nobility who mostly abandoned country for town had to be met by increased exploitation.

By the end of the middle ages the reduction of forest area had proceeded so far that it was generally believed desirable to restrict the making of clearings to exceptional necessities, except in the northeastern parts and in the distant mountain districts.

Yet a growing population increased the need for farm land, and since intensive use of the existing farm area was not attempted until the end of the 18th century, the forest had to yield still further.

3. _Methods of Restriction in Forest Use._

All ordinances issued by the princes to regulate the management of their properties contain the prescription, that permission of the _Landesherr_ is necessary for clearings, and that abandoned fields growing up to wood are to be kept as woodland; this partly for timber needs, partly for considerations of the chase. Still, Frederick the Great in colonizing East Prussia, expressed himself to the effect that he cared more for men than for wood, and enjoined his officials to colonize especially the woods far from water, which entailed even more waste of wood than where means of transportation allowed at least partial marketing.

Improvident clearings proceeded even under his reign on the Frische Nehrung between Danzig and Pillau, and started the shifting sands of that peninsula.

In the absence of all knowledge as regards the extent of existing supplies or of the increment, and with poor means of transportation, at least local distress was imminent.

To stave off a threatening timber scarcity, regulation in the use of wood was attempted by the forest ordinances, even to the extent of forbidding the hanging out of green brush to designate a drinking hall, or the cutting of May trees,--similar to our crusade in the United States against the use of Christmas trees. A diameter limit to which trees might be permitted to be cut, was also frequently urged. Regulation of forest use did not confine itself to the princely properties alone, but, in the interest of the whole, the restrictions were extended to all owners. These restrictions were directed either to the practice in the exploitation of the forest or in the use of the material. In the latter direction the attempts at reducing the consumption of building timber are of special interest. Building inspectors were to approve building plans and inspect buildings to see that they were most economically constructed; that repairs were made promptly, to avoid the necessity of more extensive ones; that new buildings replacing old ones were not built higher than the old ones. In Saxony, as early as 1560, it was ordered that the whole house must be built of stone, while elsewhere, the building of stone base walls and the use of brick roofs instead of shingles was insisted upon.

Even the number of houses in any community was restricted. Fences were to be supplanted by hedges and ditches. Economies in charcoal burning, in potash manufacture for glass works, and in the turpentine industry were prescribed, and about 1600, the burning of potash for fertilizer was forbidden entirely; but these laws proved unavailing. Even in fuel-wood a saving was to be effected by using only the poorer woods and windfalls, by instituting public bake ovens (still in use in Westphalia), by improving stoves, restricting the number of bathing rooms, etc.

The consumption of fuelwood seems to have been enormous, for we find record of 200 cords used by one family in a year and of 1,200 cords or more used by the Court at Weimar during the same time.

The substitution of turf and coal for firewood was ordered in some sections in 1697 and again in 1777, but practically not until 1780 did coal come in as a substitute. Tanbark peeling was also forbidden, or only the use of bark of trees soon to be felled was allowed. For cooperage only the top-dry oak; for coffins only soft-wood, or, according to Joseph II of Austria, no wood, but black cloth was to be used. In some parts of the country the use of oak was restricted, even as early as 1562.

For regulating practices in the forest the restrictions often took only the general form of forbidding devastation, without specifying what that meant.

Then, besides establishing a diameter limit, and regulating pasture in order to protect young growth, excluding sheep and goats entirely, an attempt was made to secure at least orderly procedure in the fellings. Foresters were to designate what was to be cut even for firewood. Marking irons and hammers were employed for this purpose by the middle of the 15th century (usually two markings, by forester and by inspector to check). And this designation by officials extended even into the private forest, where finally no felling was allowed without previous permission and designation by a forester.

The use of the litter by the small farmers had grown to a large extent in these times and it was thought desirable to stop it, but this aid to the poor peasant was so necessary that only regulating the gathering of it could be insisted upon.

It must be understood that all these various attempts at securing a conservative forest use were by no means general but refer to circumscribed territory, and much of it was only paper legislation without securing actual practice.

4. _Development of Forest Policy._

With the beginning of the 18th century we find, besides these prescriptions against wasteful use, and ordinances regulating the management of the properties of the princes, definite forest policies in some sections, having in view forest preservation and improvement of forest conditions, and also means of providing wood at moderate prices.

Between the years 1515 and 1590, most of the German States had already enacted ordinances which had the force of general law exercising police functions over private forest property, although in Prussia this general legislation did not occur until 1720. The objects in view with this legislation were entirely of a material kind: the conservation of resources. Besides securing the rights of the _Landesherr_ to the chase, it was to secure a conservative use of the princely as well as private forests, since devastation of the latter would require the former to be drawn on extravagantly; it was to stave off a timber famine, and in certain localities to assure particularly the mining industry of their wood supplies. There were, however, concessions made to the privileged and influential classes of forest owners.

By the end of the 18th century, this forest police, owing to the uncontrolled harshness and the grafting practices of the lower officials had become the most hated and distasteful part of the administration.

The argument of the protective influence of forest cover did not enter into this legislation; this argument belongs to the 19th century.

Yet reboisement of torrents had already in 1788, been recognized as a proper public measure in German Austria, although active work in that direction was not begun until nearly a century later.

The rise of prices during the 17th and 18th centuries had been very considerable, doubling, trebling and even quadrupling in the first half of the 18th century. The mercantilistic doctrines of the time led, therefore, to attempts to keep prices low by prescribing rates for wood and in general by restricting and regulating wood commerce.

This was done especially by interdicting sale to outsiders, forbidding export from the small territory of the particular prince; or, at least, giving preference to the inhabitants of the territory as purchasers and at cheaper rates.

Owing to the small size of the very many principalities, the free development of trade was considerably hampered by these regulations. Sometimes also wood imports were prohibited, as for instance, in Wurttemberg, when, in 1740, widespread windfalls had occurred which had to be worked up and threatened to overstock the market.

Wood depots under government control were established in large cities, and the amount of wood to be used per capita prescribed, as in Koenigsberg (1702).

In Berlin, in 1766, a monopoly of the fuel wood market was rented to a corporation, excluding all others except by permission of the company. This was in 1785 supplanted by government administration of the woodyards.

Another such monopoly was created in the “Nutzholzhandelsgesellschaft” (Workwood sales agency) for the export trade of building materials from Kurmark and Magdeburg, which had prior right of purchase to all timber cut within given territory, the idea being to provide cheap material for the industries. This, too, came into the hands of the State in 1771.

In Prussia, to prevent overcharges, the Jews were excluded from the wood trade in 1761.

The exercise of the Forsthoheit (princely supervision), originating in the ban forests, and favored by the mercantilistic and absolutist ideas of the 17th and 18th centuries, gradually grew until the end of the 18th century to such an extent that the forest owners themselves were not allowed to cut a tree without sanction of some forest official, and could not sell any wood without permission, even down to hop-poles, although the large landed property owners vigorously resisted this assumption of supervisory powers. Much discussion and argument regarding the origin of this right to supervision was carried on by the jurists upon the basis of Roman law doctrine, and it was proved by them to be of ancient date. The degree, however, to which this supervision was developed varied considerably in the different parts of the empire, according to different economic conditions. The interference, and the protection of forests appeared more necessary, where advanced civilization and denser population created greater need for it. We find therefore that the restrictive policy was much more developed in the Southern and Western territories than in the Northern and Eastern ones, where the development begins two centuries later.

The oldest attempts of controlling private forest property are found in Bavaria (1516), Brunswick (1590) and Wurttemberg (1614). Here, forest properties were placed either entirely under the supervision of the princely forest administration, or, at least, permission for intended fellings had to be secured. Later, these restrictions were considerably reduced in rigor (Bavaria, 1789).

In Prussia, private forest property remained free from government interference well into the 18th century. An edict by the Great Elector, in 1670, merely inveighs against the devastation of forests by their owners, but refrains from any interference; and the Forstordnung of 1720 also contains only the general injunction to the owners not to treat their forests uneconomically. But, in 1766, Frederick the Great instituted a rigid supervision providing punishment for fellings beyond a special budget determined by experts. Soon after the French revolution, however, unrestricted private ownership was re-established.

Church and cloister property had always been severely supervised, similar to the Mark and other communal forest property, under the direction either of specially appointed officials or the officials of the princes. Finally, in some sections (Hesse-Kassel, 1711; Baden, 1787), the management of these communal forests was entirely undertaken by the government.

In Prussia, by the Order of 1754, the foresters of the State were charged with the supervision of the communal forests, in which they were to designate the trees to be felled and the cultures to be executed; but as there was no pay connected with this additional duty and the districts were too large, the execution of this supervision was but indifferently performed.

In 1749, a special city forest order placed the city forests in Prussia under the provincial governments, requiring for their management the employment of a forester and the inspection of his work by the provincial forestmaster.

5. _Personnel._

Although all this supervision was probably more or less lax, the possibility of more general and incisive influence was increasing because the personnel to whom such supervision could be intrusted was at last coming into existence.

The men in whose hands at the beginning of the 18th century lay the task of developing and executing forest policies and of developing forestry practice came from two very different classes. The work in the woods fell naturally to the share of the huntsmen and forest guards, who by their practical life in the woods had secured some wood lore and developed some technical detail upon empiric basis. These so-called _holzgerechte Jaeger_ (woodcrafty hunters) prepared for their duties by placing themselves under the direction of an established huntsman, who taught them what he knew about the rules of the chase, while by questioning woodchoppers, colliers, etc., and by their own observation the knowledge of woodcraft was acquired.

At the head of affairs stood the so-called _cameralists_ or chamber officials, men who had prepared themselves by the study of philosophy, law, diplomacy and political economy for the positions of directors of finance and State administration. Rather ignorant of natural science, and without practical forestry knowledge, their efforts were not always well directed. They deserve credit, however, for having collected into encyclopædic volumes the empiric knowledge of the practitioners or Holzgerechten, and for having elaborated it more or less successfully. In this work they were joined by some of the professors of cameralia and law at the universities.

By the middle of the 18th century the hunters had so far grown in knowledge and education as to be able to produce their knowledge in books of their own. Quite a literature developed full of acrimonious warfare of opinions, as is the rule where empiricism rules supreme.

Notable progress, however, came only when hunting was placed in the background and more or less divorced from forest work.

6. _Development of Silviculture._

In addition to the restrictive measures and attempts at mere conservative lumbering without much thought of reproduction, there were as early as the 16th century silvicultural methods applied to secure or foster reproduction.

Owing to differences in local conditions and difference in necessities, this development varied greatly in various sections as to the time it took place. The Western and Middle country practiced as early as the 16th century what in the Eastern country did not appear until the 18th century. The forest ordinances, from which we derive our knowledge or inferences of these conditions, prescribed, to be sure, many things that probably were not really put into practice.

* * * * *

a. _Natural regeneration_ was at first merely _favored_, without the adoption of any very positive measures to secure it, namely, by removing the cut wood within the year, so as to give young growth a chance of establishing itself, by removing the brush so as not to smother the young growth, by keeping out cattle from the young growth (Schonung).

If the selection method of lumbering, most generally practiced without much plan, did not produce any desirable result in reproduction, the clear cutting which was practiced without system where charcoal manufacturing or river driving invited to it, did even less so. In either case, besides the defective and damaged old stubs which were left in the logging, a poor aftergrowth of undesirable character remained, as is the case in the American woods on so many areas.

As early as 1524 and 1529, we have record of a conscious attempt to secure a reproduction by leaving ten to thirty seed trees per acre; but the result was disappointing, for this practice, being applied to the shallow-rooted spruce, produced the inevitable result, namely, the seed trees were thrown by the winds.

This experience led to the prescription (in 1565) in the Palatinate to leave, besides seed trees, parts of the other stand for protection against wind damage; later, wind protection was sought by leaving parcels standing on all four sides, giving rise to a checkerboard progress of fellings or a _group system_ of reproduction, which by the middle of the 18th century had developed into the regular _strip system_, applied in Austria (1766) to fir and spruce, and in Prussia (1764) to pine. And this marginal seeding method remained for a long time the favorite method for the _conifers_.

To avoid long strips and distribute the fellings more conveniently, v. Berlepsch (in Kassel) recommended (in 1760) the cutting in echelons (curtain method, Kulissenhieb), which insured better seeding, but also increased danger from windfalls, and was never much practiced, the disadvantages of the method being shown up especially in the Prussian Forest Order of 1788.

In the first half of the 18th century it was recognized that the wind danger would be considerably reduced by making the fellings progress from East or Northeast to West. The conception of a regular, properly located felling series was first elaborated in the Harz mountains in 1745 by von Langen, who also accentuated the necessity of preserving a wind mantle on exposed situations. Both of these propositions reappear in the Prussian Order of 1780, according to which fellings are to proceed in a breadth of twenty to thirty-five rods from East to West.

The application of a _nursetree method_ for conifers was proposed in 1787 by v. Burgsdorf (Prussia), a dark position (Dunkelschlag) and a regeneration period of seven years being advocated.

In broadleaved forest, besides the selection forest, the natural result of the sprouting capacity of the hardwood had led to a coppice method which was extensively relied upon for fuel production. This was rarely, however, a simple _coppice_, for, intentionally or unintentionally, some seedlings or sprouts would be allowed to grow on, leading to a composite forest and finally to a regular _coppice with standards_ (1569, etc.), with an intentional holding over of the valuable oak and ash for standards. Probably, however, large areas of unconsciously produced composite forest exhibited sad pictures of branchy overwood with suppressed underwood of poor sprouts, injured by game and cattle--a scrubby growth, into which crept softwoods of birch and aspen. Attempts at _pruning_ such scrub growths into shape on quite an extensive scale are on record.

The recognition that more wood per acre could be secured by lengthening the rotation of the coppice, which seems to have been mostly twelve years or less, led to twenty and thirty year turns and finally to fifty, sixty and even eighty year rotations or so-called _polewood management_ (Brunswick, 1745), also called _Hochwald_ (high forest).

A full description and working plan for such a forest to be managed in eighty year rotation, the city forest of Mainz in the Odenwald and Spessart mountains, dates from 1773, and this polewood forest management became quite general after the middle of the 18th century, but in the last half of the 19th century it was generally replaced by the true high forest management under nursetrees, the experiences with the natural reproduction of conifer forest having proved the advantages of this method.

The primitive beginnings of this so-called _Femelschlag_ method (Compartment selection or shelterwood method) are found, in 1720, in Hesse Darmstadt, where Oberforstmeister von Minnigerode prescribed regular fellings progressing from north to south, in which all material down to polewood size (in selection or virgin forest) was to be removed, excepting only a number of clean boles, one every ten to twelve paces being left for seed and nursetrees. The good results in reproduction stimulated owners of adjoining estates to imitate the method (1737).

The observation that in beech forest the young crop needed protection and succeeded better when gradually freed from the shade of the seed trees, especially on south and west aspects where drought, frost and weeds are apt to injure it on sudden exposure, led to the elaboration of the principle of _successive fellings_.

In the ordinance of Hanau, as early as 1736, three grades of fellings were developed, the cutting for seed, the cutting for light, which was to begin when the young crop was knee-high, and the removal cutting when the crop was high.

This method spread rapidly and was further developed by the addition (in 1767) of a preparatory cutting, to secure a desirable seedbed, and by lengthening the period of regeneration and elaborating other detail, so that, by 1790, the principles of natural regeneration under nursetrees for beech forest were fully developed in Western Germany.

In other parts, hardwood forest management was but little developed. The Prussian Forest Ordinance of 1786 contented itself with forbidding the selection method, by declaring natural regeneration, as practiced in the pineries, not applicable; while the Austrian Ordinance of 1786 recognizes only clearing followed by planting as the general rule.

* * * * *

b. _Artificial Reforestation._ Although sporadic attempts at sowing and planting are on record as early as the beginning of the 14th century, extensive artificial reforestation did not begin until the middle of the 18th century, by which time planting methods were quite fully developed.

Among the hardwoods, the _oak_ was the first to receive special attention. By the middle of the 16th century the forest ordinances gave quite explicit instructions for planting oak in the so-called _Hutewald_, a combination of pasture and tree growth such as is found to-day in the bluegrass region of Kentucky; the remnants of these poor pasture woods with their gnarly oaks have lasted into modern times.

In the forest ordinance of Brunswick (1598) orders are given to plant on felling areas: “every full farmer shall every year at the proper time set out ten young oaks, every half farmer five, every farm laborer three, well taken up with roots (wildlings), and plant them in the commons or openings at Martini (November) or Mitfasten (Easter) and cover them with thorn brush” (to protect them against cattle).

About that time it was, indeed, incumbent on every marker to sow annually five oaks, or plant several young seedlings for every tree cut and to tend them a few years; and the custom existed in the low country,--afterwards (1700) introduced by law in Saxony--to plant in celebration of certain occurrences--a kind of _arborday_--especially to celebrate the marriage day; in order to be married the bridegroom had to prove that he had planted a certain number of oaks, which in Prussia (1719) had to be six, besides six fruit trees. The existence of this custom, now long forgotten, has given rise in the United States to the story that this is the method by which the German forest is maintained.

The method of collecting and keeping acorns over winter was well known in 1579, as is evidenced by the Hohenlohe Forest Ordinance, which advised fall sowing, but, if that did not prove successful, to prepare the ground in summer, leave it through the winter and sow in the spring.

While, in earlier times, _sowing_ seems to have had the preference, at a later period planting was practiced, at first with wildlings, but as early as 1603 we find mention of oak nurseries.

The Prussian Order of 1720 ordered the foresters to plant oaks in the openings before Christmas, for which they were to be paid, if the trees were found alive after three years. The growing and culture of oak also interested Frederick the Great, who ordered its extension everywhere. Very explicit and correct rules for growing and transplanting them, and some to which we would not subscribe, were given in the books of the 18th century. Among the planting methods we find, in 1719 and again in 1776, one similar to the Manteuffel method of planting in mounds.

While oak culture was especially fostered in Northwestern Germany, the cultivation of _conifers_ first received attention in the southwest, and in the same manner which was inaugurated by the Nuremberg seed dealer in 1368. A new idea, introduced in the Palatine Forest Ordinance (1565) and in the Bavarian Forest Ordinance (1568), was the prescription, to soak the seed before use and sow mixed with sawdust or sand, bringing the seed under with brush or iron rakes.

Carlowitz (1713) taught well the methods of collecting, extracting and keeping the seed, and even proposed seed tests. The seedbeds were to be made as for carrots, dense sowings to be thinned, and the thinnings transplanted into nursery rows, the seedbeds to be covered with moss and litter to protect them against heaving; he also discusses the question of cost. The adaptation of plant material to different sites--conifers where oaks are not suitable--was also understood (Bavarian Forest Ordinance, 1683).

As long as the old method of extracting the seed in hot stoves or ovens prevailed, conifer sowings gave but indifferent results.

In the pine forests of Prussia, during the second half of the 18th century, the method of sowing the cones on large waste and sand barrens, where the sun would make them release the seed, was practised, and before Brémontier had written his celebrated _mémoire sur les dunes_, sanddunes had been recovered with pine plantations in Germany in the manner which is still in vogue.

The _planting_ of conifers came into practice much later, and then it was mostly done with wildlings. Opinions differing as to the value of sowing or planting, it was erroneously held until the 19th century that planting was less successful and too costly in comparison with the small harvest yield, which necessitated cheapness of operations. It was only towards the end of the 18th century that planting of pine was resorted to, but merely for repairing fail places in sowings and natural regeneration, and then with a ball of earth (1779), using a hollow spade,--a costly method. The cost of a certain plantation made in 1751 is, however, reported as less than $3.00 per M., in 1770 as low as 70 cents per M. To cheapen the operations the labor was exchanged for wood, pasture or other materials or advantages.

In Prussia, in 1773, all recipients of free wood had to do service in the cultures; in 1785, every farmer had to furnish a certain amount of cones or acorns. The method, lately adopted in Russia, came into vogue in Prussia in 1719, namely, of charging, besides the value of the wood, a toll to be paid into the planting fund (about 7% of the value). This method was also imitated elsewhere.

The use of the _Waldfeldbau_ (combined farm and forest culture) was also inaugurated for the purpose of cheapening the cost of plantations (by v. Langen in 1744) when the great movement for reforesting wastes and openings began, the tree seed being sown with the grain either at once or after farm use for some years.

Regular annual planting budgets (of $50--$100--$200) were inaugurated in Brunswick by v. Langen in 1745; and in 1781, the Prussian forest administration had attained to entirely modern planting plans and annual planting budgets.

It was no wonder that the fear of a timber famine and the apparent hopelessness of bringing improvement into the existing forest conditions created anxiety and a desire to plant _rapid growers_, such as birch, willow, aspen, alder; the planting of the White Birch became so general in the beginning of the 18th century that a regular betulomania is recorded corresponding to the incipient catalpomania in the United States.

At that time, to be sure, firewood was still the main concern, and the use of these rapid growing species had some justification. But where birch was mixed in spruce plantations its baneful effects consisting in whipping off the spruce tips and injuring its neighbors were soon recognized, and much trouble was experienced in getting rid of the unwelcome addition.

The _Robinia_, which had been brought from America in 1638, was also one of the trees recommended in the middle of the 18th century and was much planted until Hartig pointed out that the expectations from it were entirely misplaced.

Of course no building material could be expected from these species, hence the larch, also a rapid grower, was transplanted from the Alps (1730 in Harz mountains), and its use was extended, as with us, to conditions for which it was not adapted.

It was principally a desire for novelty and perhaps for better, especially foreign things, that led to the planting of North American species in parks during the first half of the 18th century. But, although F. A. J. von Wangenheim’s very competent writings on the American forest-flora and on the laws of naturalization (1787) stimulated interest in that direction, the use of American species for forest planting was not inaugurated till nearly 100 years later, with the single exception of the White Pine (_P. strobus_), of which large numbers were planted.

7. _Improvement of the Crop._

Thinning of stands had been practiced early in the 16th century, not for improvement of the remaining stand so much as to secure fence material, although in 1531 the observation was already recorded that thinning improved and stimulated the remaining growth.

In the 17th century, opposite views, or, at least doubts as to its usefulness were expressed in the forest orders, and sometimes thinning was even forbidden. Even in the 18th century some of the prominent foresters, Doebel and Beckman, were opposed to it, and although others favored the operation, the practice of it remained limited.

In 1761, we find the first good statement of the theory of thinnings by Berlepsch, who advised taking out the suppressed trees when the sound poles were clear of lower and middle branches; he also accentuated the financial argument of earlier returns and increased value of the remainder.

About the same time, Zanthier recommended two thinnings, namely, for conifers first in the thirtieth to fortieth year and again in the fiftieth year, for broadleaf forest first in the forty-fifth and again in the eightieth to ninetieth year.

In 1765, the financial gain from thinnings is figured by Oettelt, and the possible reduction of the rotation due to thinnings is recognized by Leubert in 1774.

Just as the thinning in polewoods arose from the need of earlier utilization, so the weeding of young growths was done for the purpose of getting material for withes to bind the grain, etc.

The removal of coppice shoots in oak plantings was practiced in Prussia in 1719, and the thinning of too dense sowings was advised by Carlowitz in 1713. Yet much later, even such an intelligent man as Oettelt inveighed against the weeding out of the birch in spruce sowings because “nature prefers variety, with which preference it is not good to interfere.”

This was in opposition to v. Langen (1745), who prescribed for the first time regular cleaning or weeding, especially the removal of the softwoods, aspen and birch, and of coppice shoots from seedling forest. It was also known that this weeding is best done “in the full sap,” in order to kill the stocks.

8. _Methods of Regulating Forest Management._

Organized forest management was slower to develop than silvicultural methods. The first attempts to bring order into the progress of fellings took the form of dividing the whole area into a certain number of felling areas (12, 16, 20, 30, etc.), several ordinances dating from the middle of the 15th and 17th centuries containing prescriptions to that effect.

It is doubtful whether the numbers of these areas indicate years of rotation, in which case they could only have applied to coppice, or whether they indicate periods of return in selection forest, although the historians seem to jump to the former conclusion. The area division practiced by v. Langen in the Harz mountains (1745), who prescribed the division of larger districts into fifty to sixty, of smaller districts into twenty to thirty felling areas, also leaves it doubtful, whether the areas corresponded to an assumed rotation or to a period of return.

At first, the division was not into equal areas, for no survey existed, and its object was simply to localize the cutting and provide orderly progress. The subdivision was made in the mountain country by following the topography, valleys and ridges, while in the plain the lines opened up for purposes of the chase (to set up nets), called _Schneisen_ or _Gestelle_ (rides), bounding square areas called _Jagen_, _Quadrat_, _Stallung_, were used for the limitation of the felling areas. Most commonly, however, largely due to absence of surveys, the ordered division did not materialize, but existed only on paper.

With more exact measuring of areas, and with the conception of a rotation or longer periods of return, it was recognized that the inequality of the sites or soil qualities, especially in mountain districts, produced very unequal felling budgets. To overcome this inequality, Jacobi, in Goettingen (1741) introduced _proportional_ felling areas, making the felling areas on poor sites permanently larger.

Similarly, v. Langen and Zanthier attempt to secure equal annual returns without slavishly holding to the geometric division, merely making sure that the total area be cut over in the predetermined rotation.

The first attempts to introduce a regulated management by making a _volume_ division the basis is recorded from the Harz mountains in 1547. This method, based on very crude estimates although upon very fair forest description, was continued into the 18th century.

In the last half of the 18th century all these crude methods were improved, and applied on extensive areas.

In 1785, Zanthier combined area and volume division, determining the felling budget on each felling area by counting and estimating the trees and calculating how many trees could be used annually under a sustained yield management; the area division being used only as a check or means of control.

A very considerable advance was made by Oettelt, (who surveyed and regulated the Weimar forests in 1760) in the elaboration of details and establishment of proper principles for regulating the felling budget.

In his forest description he introduces for the first time periodic age classes, usually six, but of uneven length: Young growth, below twelve years; thicket, twelve to twenty-four years; polewood, twenty-four to forty years; clear timber, forty to fifty; medium timber, fifty to seventy-five; mature timber, seventy-five years and over.

He divides the forest into proportional areas (which were marked by stones in the woods), equalizing them according to age, quality, increment, soil, exposure, so as to secure equal annual budgets; the stands were ranged into seven or eight unequal age classes and each into as many annual felling areas as there are years in the age class; if some of the age classes were absent, he extended the time for cutting in the older class until the younger had grown to the proper age and by varying the cut from good to poor sites for stands he tried to even out the budgets. The volume budget he determined by average increment measurements. This method was, however, much too far advanced and required too much mathematics to find imitators at that time.

Another method which proved also too complex for the foresters of the time was that of v. Wedell; nevertheless, by 1790, he had by it put into working order 800,000 acres in Silesia. He divided this area into districts, the districts into blocks or management classes, and used an elaborated proportional area division for determining the felling budget. He distinguished quality of stand and quality of site, and made four site classes. The volume of stock, he found by means of sample areas, to which he added the increment in order to find the total volume for harvest, when it could be determined how long with a given budget the stands would last, or what average annual felling budget could be taken before the next age-class would be mature.

In the North German plain, with very uniform conditions of soil and timber, the method of equal felling areas was the most natural and most easily applied.

Frederick the Great, who took a considerable interest in forestry matters, ordered such an area division for the State pineries in 1740, fixing upon different numbers of felling areas, but finally, in 1770, deciding on a rotation of seventy years. Lack of personnel retarded progress in this forest survey and regulation until in 1778 v. Kropff undertook the direction. Not agreeing with his master regarding the short rotation of seventy years, he arranged to have each district divided into two working blocks, and by cutting alternately in these, managed to double that rotation. His successor, Hennert, in 1788, devised a new method by introducing allotment of a number of annual felling areas to a period of the rotation when at least the periodic budget could be equalized. A value or money yield equalization of the felling budgets was also attempted.

For easier handling, the forest was divided into small compartments or Jagen and a classification of four, still uneven, periodic age classes (of different length for conifers and broadleaved forest), and three site qualities were employed. The merchantable stock was ascertained by a sample area method and the felling budget by dividing the oldest age class by the number of years it must last until the next was ready. Since no attempt was made to secure a proper age class gradation, the method failed to improve conditions for the next rotation.

Some 500,000 acres were regulated according to this plan in Prussia, probably very superficially.

In 1789, Bavaria also ordered a division into annual felling areas.

In all these methods of regulating the yield or budget, the area played the main role, the volume being only a secondary consideration.

The first elaboration of a pure volume division was made by Beckman in 1759. He estimated stock on hand by trees and guessed more or less at the increment, allowing 2.5, 2, and 1% for the different sites, and then made a year to year calculation of stock for 125 years. How the felling budget was finally determined is not known.

Two methods were simultaneously devised in Württemberg in 1783, which form the transition to the so-called _allotment_ methods, making periodic age classes of an equal number of years and allotting either felling areas or volumes to each period of the rotation. Incapacity of the officials prevented the application of the one method, while the other, devised by Maurer, remained also only a proposition.

But, in 1788, Kregting in his Mathematical Contributions to Forestry Science teaches a pure volume allotment method with ten year age classes and nearly all the apparatus which was afterward developed by Hartig, who in the next period dominated to such a large extent the development of forestry in all its branches.

9. _Improvements in Methods of Mensuration._

In scientific direction, the mathematical disciplines were the first to be developed; the natural sciences received attention much later.

A considerable amount of mathematical knowledge was required for this work of forest organization. The mathematical apparatus of the foresters even at the end of this period was rather slender, but its development went hand in hand with the development of these methods of regulation; and even elaborate mathematical formulæ for determining felling budgets were not absent.

Until nearly the middle of the 18th century, surveys of exact nature were almost unknown; only when the division into equal or proportionate felling areas became the basis for determining the felling budgets, did the necessity for such surveys present itself.

Plane table and compass were the instruments which came into use in the beginning of the 18th century. But not until the latter half of that century were extensive forest surveys and maps of various character made, especially in Prussia under Wedell, Kropff and Hennert.

The methods of measurement of wood developed still later. Until Oettelt’s time no method of precise determination of volumes was known, everything being estimated by cords or by diameter breast-high and height, or by the number of boards which a tree would make (board feet?).

The diameter was sometimes used as a price maker, the price increasing in direct proportion to the diameter increase. Oettelt calculated the volume of coniferous trees as cones, and _Vierenklee_, who wrote a book on mathematics for the use of foresters, calculated timbers with the top removed by using the average diameter, to which Hennert added the volume of a cone with the difference of the two diameters as a base, to make the total tree volume.

Most measurements of standing trees were, of course, made on the circumference, for, in the absence of calipers, the diameter could be directly measured only on the felled tree. Doebel had already measured the height by means of a rectangular triangle, and the first real hypsometer with movable sights was described by Jung in 1781; and a complete instrument, which could be used for measuring both height and diameter at any height, similar to some more modern ones, was constructed by Reinhold.

Determination of the real wood contents in a cord of wood and of the volume of bark by measurement was taught by Oettelt, and the method of immersion in water and measuring the displaced volume, by Hennert (1782).

In 1785, Krohne first called attention to the variation of the increment in different age classes and the need of determining the accretion for each separately.

In 1789, Trunk taught how to determine average felling age increment, and also the method of determining the change of diameter classes, which is now used by the United States Forest Service: “On good soil a tree grows one inch in three years, on medium soil in four years, on poor soil in five years.” With this knowledge, the attainment of a given diameter, or the change from one diameter or age class to the next could be calculated.

Volume tables were at Trunk’s command, and Paulsen in 1787, Kregting in 1788, mention periodic yield tables; but generally speaking “ocular taxation” or estimating was the rule, checked by experience in actual fellings, the method of the American timber looker. Generally, of course, only the log timber was estimated as with us, and only the very roughest estimating or rather guessing was in vogue until near the end of the period.

The first attempt at closer measurement was made by Beckman (1756), who surrounded the area to be measured with twine, drove a colored wooden peg into each tree, one color for each diameter class, when, knowing the original number of pegs that had been taken out, the difference gave the number of trees in each diameter class, and by multiplying the average cubic contents of a measured sample tree in each class by the number in the class its volume was found.

The method, often employed at present, of ascertaining by tally the diameter classes on strips forty to fifty paces wide, the so-called strip survey, was described by Zanthier in 1763.

These measurements were usually confined to sample areas, the use of such being already known in 1739. The contents of the sample area, if a special degree of accuracy was desired, were ascertained by felling the whole and measuring.

Oettelt, of mathematical fame, was the first to publish something about the determination of the age of trees by counting rings, although the practice probably antedates this account. He knew of the dependence of the ring width on the site and on the density of the stand.
