Chapter XXIX: Book XVII (4)

They must not be touched with the knife before the end of three years; and then the branches are preserved, on each side in its turn, the pruning being done in alternate years. In the sixth year the vine is united to the tree. In Italy beyond the Padus, in addition to the trees already mentioned, they plant for their vines the cornel, the opulus, the linden, the maple, the ash, the yoke-elm, and the quercus; while in Venetia they grow willows for the purpose, on account of the humidity[3151] of the soil. The top of the elm is lopped away, and the branches of the middle are regularly arranged in stages; no tree in general being allowed to exceed twenty feet in height. The stories begin to spread out in the tree at eight feet from the ground, in the hilly districts and upon dry soils, and at twelve in champaign and moist localities. The hands[3152] of the trunk ought to have a southern aspect, and the branches that project from them should be stiff and rigid like so many fingers; at the same time due care should be taken to lop off the thin beardlike twigs, in order to check the growth of all shade. The interval best suited for the trees, if it is the grower’s intention to keep the soil turned up with the plough, is forty feet back and front, and twenty at the side; if it is not to be turned up, then twenty feet[3153] every way will do. A single tree is often made to support as many as ten vines, and the grower is greatly censured who attaches less than three. It is worse than useless to attach the vine before the tree has gained its full strength, as in such case its rapidity of growth would only tend to kill the tree. It is necessary to plant the vine in a trench three feet in depth, leaving an interval of one foot between it and the tree. In this case there is no necessity for using mallet shoots, or for going to any expense in spading or digging; for this method of training on trees has this advantage in particular, that it is beneficial even to the vine that corn should be sown in the same soil; in addition to which, from its height, it is quite able to protect itself, and does not call for the necessity, as in the case of an ordinary vineyard, of enclosing it with walls and hedges or ditches, made at a considerable expense, to protect it from injury by animals.

In the method of training upon trees, reproduction from quicksets or from layers is the only mode employed of all those that have been previously described; the growing by layers being effected two different ways, as already mentioned. The plan, however, of growing from layers in baskets set upon the stages[3154] of the tree is the most approved one, as it ensures an efficient protection from the ravages of cattle; while, according to another method, a vine or else a stock-branch is bent into the ground near the tree it has previously occupied, or else the nearest one that may be at liberty. It is recommended that all parts of the parent tree that appear above ground should then be scraped, so that it may not throw out wood; while at the same time there are never less than four buds on the part that is put into the ground for the purpose of taking root; there are also two buds left above ground at the head. The vine intended for training on a tree is planted in a furrow four feet long, three broad, and two and a half in depth. At the end of a year the layer is cut to the pith, to enable it to strengthen gradually at the root; after which, the end of the branch is pruned down to within two buds from the ground. At the end of two years the layer is completely separated from the stock, and buried deeper in the ground, that it may not shoot at the place where it has been cut. As to the quicksets, they ought to be removed directly after the vintage.

In more recent times, a plan has been discovered of planting a dragon branch near the tree—that being the name given to an old stock-branch that has become hard and tough in the course of years. For this purpose, it is cut as long as possible, and the bark is taken off from three-fourths of its length, that being the portion which is to be buried in the ground; hence it is, too, that it is called a “barked”[3155] plant. It is then laid at full length in the furrow, the remaining part protruding from the ground and reclining against the tree. This method is the most speedy one that can be adopted for growing the vine. If the vine is meagre or the soil impoverished, it is usual to keep it cut down as near to the ground as possible, until such time as the root is strengthened. Care, too, should be taken not to plant it covered with dew,[3156] nor yet while the wind is blowing from the north. The vine itself ought to look towards the north-east, but the young stock-shoots should have a southern aspect.

There should not be too great haste[3157] in pruning a young vine, but a beginning should be made by giving the wood and foliage a circular form, care being taken not to prune it until it has become quite strong; it should be remembered, too, that the vine, when trained upon a tree, is generally a year later in bearing fruit than when grown on the cross-piece. There are some persons, again, who altogether forbid that a vine should be pruned until such time as it equals the tree in height. At the first pruning it may be cut to within six feet from the ground, below which a shoot must be left, and encouraged to run out by bending the young wood. Upon this shoot, when pruned, there should not be more than three buds left. The branches that take their rise from these buds should be trained in the following year upon the lowermost stages of the tree, and so in each successive year taught to climb to the higher ones. Care, too, should always be taken to leave one hard, woody branch at each stage, as well as one breeding shoot, at liberty to mount as high as it pleases. In addition to these precautions, in all pruning, those shoots should be cut off which have borne fruit the last year, and after the tendrils[3158] have been cut away on every side fresh branches should be trained to run along the stages. In Italy the pruning is so managed that the shoots and tendrils of the vines are arranged so as to cover the branches of the tree, while the shoots of the vine in their turn are surrounded with clusters of grapes. In Gallia, on the other hand, the vine is trained to pass from tree to tree. On the Æmilian Way, again, the vine is seen embracing the trunks of the Atinian elms that line the road, while at the same time it carefully avoids their foliage.[3159]

It is a mark of ignorance in some persons to suspend the vine with a cord beneath the branches of the tree, to the great risk of stifling it; for it ought to be merely kept up with a withe of osier, and not tightly laced. Indeed, in those places where the willow abounds, the withes that it affords are preferred, on account of their superior suppleness, while the Sicilians employ for the purpose a grass, which they call “ampelodesmos:”[3160] throughout the whole of Greece, rushes, cyperus, and sedge[3161] are similarly employed. When at any time the vine has been liberated from its bonds, it should be allowed to range uncontrolled for some days, and to spread abroad at pleasure, as well as to recline upon the ground which it has been looking down upon the whole year through. For in the same manner that beasts of burden when released from the yoke, and dogs when they have returned from the chase, love to roll themselves on the ground, just so does the vine delight to stretch its loins. The tree itself, too, seems to rejoice, and, thus relieved from the continuous weight which has burdened it, to have all the appearance of now enjoying a free respiration. Indeed, there is no object in all the economy of Nature that does not desire certain alternations for the enjoyment of rest, witness the succession of night and day, for instance. It is for this reason that it is forbidden to prune the vine directly the vintage is over, and while it is still exhausted by the process of reproduction.

Directly the vine has been pruned, it ought to be fastened again to the tree, but in another place; for there is no doubt that it feels very acutely the indentations that are made in it by the holdfasts. In the Gallic method of cultivation they train out two branches at either side, if the trees are forty feet apart, and four if only twenty; where they meet, these branches are fastened together and made to grow in unison; if, too, they are anywhere deficient in number or strength, care is taken to fortify them by the aid of small rods. In a case, however, where the branches are not sufficiently long to meet, they are artificially prolonged by means of a hook, and so united to the tree that desires their company. The branches thus trained to unite they used to prune at the end of the second year. But where the vine is aged, it is a better plan to give them a longer time to reach the adjoining tree, in case they should not have gained the requisite thickness; besides which, it is always good to encourage the growth of the hard wood in the dragon branches.

There is yet another method,[3162] which occupies a middle place between this mode of propagation and that by layers. It consists of laying the entire vine in the earth, and then splitting the stock asunder by means of wedges; the fibrous portions are then trained out in as many furrows, care being taken to support each of the slender plants by fastening it to a stake, and not to cut away the branches that shoot from the sides. The growers of Novara, not content with the multitude of shoots that run from tree to tree, nor yet with an abundance of branches, encourage the stock-branches to entwine around forks planted in the ground for the purpose; a method, however, which, in addition to the internal defects arising from the soil, imparts a harshness to the wine.

There is another fault, too, that is committed by the people of Varracina,[3163] near Rome—they only prune their vines every other year; not, indeed, because it is advantageous to the tree, but from a fear lest, from the low prices fetched by their wines, the expense might exceed the profits. At Carseoli they adopt a middle course, by pruning away only the rotten parts of the vine, as well as those which are beginning to wither, and leaving the rest to bear fruit, after thus clearing away all superfluous incumbrances. The only nutriment they give it is this exemption from frequent pruning; but unless the soil should happen to be a very rich one, the vine, under such a method of cultivation, will very soon degenerate to a wild state.

The vine that is thus trained requires the ground to be ploughed very deep, though such is not the case for the sowing there of grain. It is not customary to cut away the leaves in this case, which, of course, is so much labour spared. The trees themselves require pruning at the same period as the vine, and are thinned by clearing away all useless branches, and such parts as would only absorb the nutriment. We have already[3164] stated that the parts that are lopped should never look north or south: and it will be better still, if they have not a western aspect. The wounds thus made are very susceptible for a considerable time, and heal with the greatest difficulty, if exposed to excesses of cold or heat. The vine when trained on a tree enjoys advantages that are not possessed by the others; for the latter have certain fixed aspects, while in the former, it is easy to cover up the wounds made in pruning, or to turn them whichever way you please. When trees are pruned at the top, cup-like cavities should be formed[3165] there, to prevent the water from lodging.

CHAP. 36.—HOW GRAPES ARE PROTECTED FROM THE RAVAGES OF INSECTS.

Stays, too, should be given to the vine for it to take hold of and climb upwards, if they are taller than it. (24.) Espaliers[3166] for vines of a high quality should be cut, it is said, at the Quinquatria,[3167] and when it is intended to keep the grapes, while the moon is on the wane. We are assured, moreover, that those which are cut at the change of the moon, are exempt from the attacks of all insects.[3168] According to another system, it is said that vines should be pruned by night at full moon, and while it is in Leo, Scorpio, Sagittarius, or Taurus: and that, in general, they ought to be planted either when the moon is at full or on the increase. In Italy, ten workmen will suffice for one hundred jugera of vineyard.

CHAP. 37.—THE DISEASES OF TREES.

Having now treated sufficiently at length of the planting and cultivation of trees—(for we have already said enough of the palm[3169] and the cytisus,[3170] when speaking of the exotic trees)—we shall proceed, in order that nothing may be omitted, to describe other details relative to their nature, which are of considerable importance, when taken in connection with all that precedes. Trees, we find, are attacked by maladies; and, indeed, what created thing is there that is exempt from these evils? Still however, the affections of the forest trees, it is said, are not attended[3171] with danger to them, and the only damage they receive is from hail-storms while they are budding and blossoming; with the exception, indeed, of being nipped either by heat or cold blasts in unseasonable weather; for frost, when it comes at the proper times, as we have already stated,[3172] is serviceable to them. “Well but,” it will be said, “is not the vine sometimes killed with cold?” No doubt it is, and this it is through which we detect inherent faults in the soils, for it is only in a cold soil that the vine will die. Just in the same way, too, in winter we approve of cold, so long as it is the cold of the weather, and not of the ground. It is not the weakest trees, too, that are endangered in winter by frost, but the larger ones. When they are thus attacked, it is the summit that dries away the first, from the circumstance that the sap becomes frozen before it is able to arrive there.

Some diseases of trees are common to them all, while others, again, are peculiar to individual kinds. Worms[3173] are common to them all, and so, too, is sideration,[3174] with pains in the limbs,[3175] which are productive of debility in the various parts. Thus do we apply the names of the maladies that prevail among mankind to those with which the plants are afflicted. In the same way, too, we speak of their bodies being mutilated, the eyes of the buds being burnt up, with many other expressions of a similar nature. It is in accordance with the same phraseology that we say that trees are afflicted with hunger or indigestion, both of which result from the comparative amount of sap that they contain; while some, again, are troubled with obesity, as in the case of all the resinous trees, which, when suffering from excessive fatness, are changed into a torch-tree.[3176] When the roots, too, begin to wax fat, trees, like animals, are apt to perish from excess of fatness. Sometimes, too, a pestilence[3177] will prevail in certain classes of trees, just as among men, we see maladies attack, at one time the slave class, and at another the common people, in cities or in the country, as the case may be.

Trees are more or less attacked by worms; but still, nearly all are subject to them in some degree, and this the birds[3178] are able to detect by the hollow sound produced on tapping at the bark. These worms even have now begun to be looked upon as delicacies[3179] by epicures, and the large ones found in the robur are held in high esteem; they are known to us by the name of “cossis;” and are even fed with meal, in order to fatten them! But it is the pear, the apple, and the fig[3180] that are most subject to their attacks, the trees that are bitter and odoriferous enjoying a comparative exemption from them. Of those which infest the fig, some breed in the tree itself, while others, again, are produced by the worm known as the cerastes; they all, however, equally assume the form of the cerastes,[3181] and emit a small shrill noise. The service-tree is infested, too, with a red hairy worm, which kills it; and the medlar, when old, is subject to a similar malady.

The disease known as sideration entirely depends upon the heavens; and hence we may class under this head, the ill effects produced by hail-storms, carbunculation,[3182] and the damage caused by hoar-frosts. When the approach of spring tempts the still tender shoots to make their appearance, and they venture to burst forth, the malady attacks them, and scorches up the eyes of the buds, filled as they are with their milky juices: this is what upon flowers they call “charcoal”[3183] blight. The consequences of hoar-frost to plants are even more dangerous still, for when it has once settled, it remains there in a frozen form, and there is never any wind to remove it, seeing that it never prevails except in weather that is perfectly calm and serene. Sideration, however, properly so called, is a certain heat and dryness that prevails at the rising of the[3184] Dog-star, and owing to which grafts and young trees pine away and die, the fig and the vine more particularly. The olive, also, besides the worm, to which it is equally subject with the fig, is attacked by the measles,[3185] or as some think fit to call it, the fungus or platter; it is a sort of blast produced by the heat of the sun. Cato[3186] says that the red moss[3187] is also deleterious to the olive. An excessive fertility, too, is very often injurious to the vine and the olive. Scab is a malady common to all trees. Eruptions,[3188] too, and the attacks of a kind of snail that grows on the bark, are diseases peculiar to the fig, but not in all countries; for there are some maladies that are prevalent in certain localities only.

In the same way that man is subject to diseases of the sinews, so are the trees as well, and, like him, in two different ways. Either[3189] the virulence of the disease manifests itself in the feet, or, what is the same thing, the roots of the tree, or else in the joints of the fingers, or, in other words, the extremities of the branches that are most distant from the trunk. The parts that are thus affected become dry and shrivel up: the Greeks have appropriate names[3190] by which to distinguish each of these affections. In either case the first symptoms are that the tree is suffering from pain, and the parts affected become emaciated and brittle; then follows rapid consumption and ultimately death; the juices being no longer able to enter the diseased parts, or, at all events, not circulating in them. The fig is more particularly liable to this disease: but the wild fig is exempt from all that we have hitherto mentioned. Scab[3191] is produced by viscous dews which fall after the rising of the Vergiliæ; but if they happen to fall copiously, they drench the tree, without making the bark rough. When the fig is thus attacked, the fruit falls off while green; and so, too, if there is too much rain. The fig suffers also from a superfluity of moisture in the roots.

In addition to worms and sideration, the vine is subject to a peculiar disease of its own, which attacks it in the joints, and is produced from one of the three following causes:—either the destruction of the buds by stormy weather, or else the fact, as remarked by Theophrastus, that the tree, when pruned, has been cut with the incisions upwards,[3192] or has been injured from want of skill in the cultivator. All the injury that is inflicted in these various ways is felt by the tree in the joints more particularly. It must be considered also as a species of sideration, when the cold dews make the blossoms fall off, and when the grapes harden[3193] before they have attained their proper size. Vines also become sickly when they are perished with cold, and the eyes are frost-bitten just after they have been pruned. Heat, too, out of season, is productive of similar results: for everything is regulated according to a fixed order and certain determinate movements. Some maladies, too, originate in errors committed by the vine-dresser; when they are tied too tight, for instance, as already mentioned,[3194] or when in trenching round them the digger has struck them an unlucky blow, or when in ploughing about them the roots have been strained through carelessness, or the bark has been stripped from off the trunk: sometimes, too, contusions are produced by the use of too blunt a pruning-knife. Through all the causes thus enumerated the tree is rendered more sensitive to either cold or heat, as every injurious influence from without is apt to concentrate in the wounds thus made. The apple, however, is the most delicate of them all, and more particularly the one that bears the sweetest fruit. In some trees weakness induced by disease is productive of barrenness, and does not kill the tree; as in the pine[3195] for instance, or the palm, when the top of the tree has been removed; for in such case the tree becomes barren, but does not die. Sometimes, too, the fruit itself is sickly, independently of the tree; for example, when there is a deficiency of rain, or of warmth, or of wind, at the periods at which they usually prevail, or when, on the other hand, they have prevailed in excess; for in such cases the fruit will either drop off or else deteriorate. But the worst thing of all that can befall the vine or the olive, is to be pelted with heavy showers just when the tree is shedding its blossom, for then the fruit is sure to fall off[3196] as well.

Rain, too, is productive of the caterpillar, a noxious insect that eats away the leaves, and, some of them, the blossoms as well; and this in the olive even, as we find the case at Miletus; giving to the half-eaten tree a most loathsome appearance. This pest is produced by the prevalence of a damp, languid heat; and if the sun should happen to shine after this with a more intense heat and burn them up, this pest only gives place to another[3197] just as bad, the aspect only of the evil being changed.

There is still one other affection that is peculiar to the olive and the vine, known as the “cobweb,”[3198] the fruit being enveloped in a web, as it were, and so stifled. There are certain winds, too, that are particularly blighting to the olive and the vine, as also to other fruits as well: and then besides, the fruits themselves, independently of the tree, are very much worm-eaten in some years, the apple, pear, medlar, and pomegranate for instance. In the olive the presence of the worm may be productive of a twofold result: if it grows beneath the skin, it will destroy the fruit, but if it is in the stone, it will only gnaw it away, making the fruit all the larger. The prevalence of showers after the rising of Arcturus[3199] prevents them from breeding; but if the rains are accompanied with wind from the south, they will make their appearance in the ripe fruit even, which are then very apt to fall. This happens more particularly in moist, watery localities; and even if they do not fall, the olives that are so affected are good for nothing. There is a kind of fly also that is very troublesome to some fruit, acorns and figs for instance: it would appear that they breed from the juices[3200] secreted beneath the bark, which at this period are sweet. These trees, too, are generally in a diseased state when this happens.

There are certain temporary and local influences which cause instantaneous death to trees, but which cannot properly be termed diseases; such, for example, as consumption, blast, or the noxious effects of some winds that are peculiar to certain localities; of this last nature are the Atabulus[3201] that prevails in Apulia, and the Olympias[3202] of Eubœa. This wind, if it happens to blow about the winter solstice, nips the tree with cold, and shrivels it up to such a degree that no warmth of the sun can ever revive it. Trees that are planted in valleys, and are situate near the banks of rivers, are especially liable to these accidents, the vine more particularly, the olive, and the fig. When this has been the case, it may instantly be detected the moment the period for germination arrives, though, in the olive, somewhat later. With all of these trees, if the leaves fall off, it is a sign that they will recover; but if such is not the case, just when you would suppose that they have escaped uninjured, they die. Sometimes, however, the leaves will become green again, after being dry and shrivelled. Other trees, again, in the northern regions, Pontus and Phrygia, for example, suffer greatly from cold or frost, in case they should continue for forty days after the winter solstice. In these countries, too, as well as in other parts, if a sharp frost or copious rains should happen to come on immediately after fructification, the fruit is killed in a very few days even.

Injuries inflicted by the hand of man are productive also of bad effects. Thus, for instance, pitch, oil, and grease,[3203] if applied to trees, and young ones more particularly, are highly detrimental. They may be killed, also, by removing a circular piece of the bark from around them, with the exception, indeed, of the cork-tree,[3204] which is rather benefitted than otherwise by the operation; for the bark as it gradually thickens tends to stifle and suffocate the tree: the andrachle,[3205] too, receives no injury from it, if care is taken not to cut the body of the tree. In addition to this, the cherry, the lime, and the vine shed their bark;[3206] not that portion of it, indeed, which is essential to life, and grows next the trunk, but the part that is thrown off, in proportion as the other grows beneath. In some trees the bark is naturally full of fissures, the plane for instance: in the linden it will all but grow again when removed. Hence, in those trees the bark of which admits of cicatrization, a mixture of clay and dung[3207] is employed by way of remedy; and sometimes with success, in case excessive cold or heat does not immediately supervene. In some trees, again, by the adoption of these methods death is only retarded, the robur and the quercus,[3208] for example. The season of the year has also its peculiar influences; thus, if the bark is removed from the fir and the pine, while the sun is passing through Taurus or Gemini, the period of their germination, they will instantly die, while in winter they are able to withstand the injurious effects of it much longer: the same is the case, too, with the holm-oak, the robur, and the quercus. In the trees above mentioned, if it is only a narrow circular strip of bark that is removed, no injurious effects will be perceptible; but in the case of the weaker trees, as well as those which grow in a thin soil, the same operation, if performed even on one side only, will be sure to kill them. The removal of the top,[3209] in the pitch-tree, the cedar, and the cypress is productive of a similar result; for if it is either cut off or destroyed by fire, the tree will not survive: the same is the case, too, if they are bitten by the teeth of animals.

Varro[3210] informs us, too, as we have already stated,[3211] that the olive, if only licked by a she-goat, will be barren.[3212] When thus injured, some trees will die, while in others the fruit becomes deteriorated, the almond,[3213] for instance, the fruit of which changes from sweet to bitter. In other cases, again, the tree is improved[3214] even—such, for instance, as the pear known in Chios as the Phocian pear. We have already mentioned[3215] certain trees, also, that are all the better for having the tops removed. Most trees perish when the trunk is split; but we must except the vine, the apple, the fig, and the pomegranate. Others, again, will die if only a wound is inflicted: the fig, however, as well as all the resinous trees, is proof against such injury. It is far from surprising that, when the roots of a tree are cut, death should be the result; most of them perish, however, when, not all the roots, but only the larger ones, and those which are more essential to life, have been severed.

Trees, too, will kill one another[3216] by their shade, or the density of their foliage, as also by the withdrawal of nourishment. Ivy,[3217] by clinging to a tree, will strangle[3218] it. The mistletoe, too, is far from beneficial, and the cytisus is killed by the plant to which the Greeks have given the name of halimon.[3219] It is the nature of some plants not to kill, but to injure, by the odour they emit, or by the admixture of their juices; such is the influence exercised by the radish and the laurel upon the vine.[3220] For the vine may reasonably be looked upon as possessed of the sense of smell, and affected by odours in a singular degree; hence, when it is near a noxious exhalation, it will turn away and withdraw from it. It was from his observation of this fact that Androcydes borrowed the radish[3221] as his antidote for drunkenness, recommending it to be eaten on such occasions. The vine, too, abhors all coleworts and garden herbs, and the hazel[3222] as well; indeed it will become weak and ailing if they are not removed to a distance from it. Nitre, alum, warm sea-water, and the shells of beans[3223] and fitches act as poisons on the vine.

CHAP. 38. (25.)—PRODIGIES CONNECTED WITH TREES.

Among the maladies which affect the various trees, we may find room for portentous prodigies also. For we find some trees that have never had a leaf upon them; a vine and a pomegranate bearing[3224] fruit adhering to the trunk, and not upon the shoots or branches; a vine, too, that bore grapes but had no leaves; and olives that have lost their leaves while the fruit remained upon the tree. There are some marvels also connected with trees that are owing to accident; an olive that was completely burnt, has been known to revive, and in Bœotia, some fig-trees that had been quite eaten away by locusts budded afresh.[3225] Trees, too, sometimes change their colour, and turn from black to white; this, however, must not always be looked upon as portentous, and more particularly in the case of those which are grown from seed; the white poplar, too, often becomes black. Some persons are of opinion also that the service-tree, if transplanted to a warmer locality, will become barren. But it is a prodigy, no doubt, when sweet fruits become sour, or sour fruits sweet; and when the wild fig becomes changed into the cultivated one, or vice versâ. It is sadly portentous,[3226] too, when the tree becomes deteriorated by the change, the cultivated olive changing into the wild, and the white grape or fig becoming black: such was the case, also, when upon the arrival of Xerxes there, a plane-tree at Laodicea was transformed into an olive. In such narratives as these, the book written in Greek by Aristander abounds, not to enter any further on so extended a subject; and we have in Latin the Commentaries of C. Epidius, in which we find it stated that trees have even been known to speak. In the territory of Cumæ, a tree, and a very ominous presage it was, sank into the earth shortly before the civil wars of Pompeius Magnus began, leaving only a few of the branches protruding from the ground. The Sibylline Books were accordingly consulted, and it was found that a war of extermination was impending, which would be attended with greater carnage the nearer it should approach the city of Rome.

Another kind of prodigy, too, is the springing up of a tree in some extraordinary and unusual place, the head of a statue, for instance, or an altar, or upon another tree even.[3227] A fig-tree shot forth from a laurel at Cyzicus, just before the siege of that city; and so in like manner, at Tralles, a palm issued from the pedestal of the statue of the Dictator Cæsar, at the period of his civil wars. So, too, at Rome, in the Capitol there, in the time of the wars against Perseus, a palm-tree grew from the head of the statue of Jupiter, a presage of impending victory and triumphs. This palm, however, having been destroyed by a tempest, a fig-tree sprang up in the very same place, at the period of the lustration made by the censors M. Messala and C. Cassius,[3228] a time at which, according to Piso, an author of high authority, all sense of shame had been utterly banished. Above all the prodigies, however, that have ever been heard of, we ought to place the one that was seen in our own time, at the period of the fall of the Emperor Nero, in the territory of Marrucinum; a plantation of olives, belonging to Vectius Marcellus, one of the principal members of the Equestrian order, bodily crossed the public highway, while the fields that lay on the opposite side of the road passed over to supply the place which had been thus vacated by the olive-yard.[3229]

CHAP. 39. (26.)—TREATMENT OF THE DISEASES OF TREES.

Having set forth the various maladies by which trees are attacked, it seems only proper to mention the most appropriate remedies as well. Some of these remedies may be applied to all kinds of trees in common, while others, again, are peculiar to some only. The methods that are common to them all, are, baring the roots, or moulding them up, thus admitting the air or keeping it away, as the case may be; giving them water, or depriving them of it, refreshing them with the nutritious juices of manure, and lightening them of their burdens by pruning. The operation, too, of bleeding,[3230] as it were, is performed upon them by withdrawing their juices, and the bark is scraped all round[3231] to improve them. In the vine, the stock branches are sometimes lengthened out, and at other times repressed; the buds too are smoothed, and in a measure polished up, in case the cold weather has made them rough and scaly. These remedies are better suited to some kinds of trees and less so to others: thus the cypress, for instance, has a dislike to water, and manifests an aversion to manure, spading round it, pruning, and, indeed, remedial operations of every kind; nay, what is more, it is killed by irrigation, while, on the other hand, the vine and the pomegranate receive their principal nutriment from it. In the fig, again, the tree is nourished by watering, while the very same thing will make the fruit pine and die: the almond, too, if the ground is spaded about it, will lose its blossom. In the same way, too, there must be no digging about the roots of trees when newly grafted, or indeed until such time as they are sufficiently strong to bear. Many trees require that all superfluous burdens should be pruned away from them, just as we ourselves cut the nails and hair. Old trees are often cut down to the ground, and then shoot up again from one of the suckers; this, however, is not the case with all of them, but only those, the nature of which, as we have already stated,[3232] will admit of it.

CHAP. 40.—METHODS OF IRRIGATION.

Watering is good for trees during the heats of summer, but injurious in winter; the effects of it are of a varied nature in autumn, and depend upon the peculiar nature of the soil. Thus, in Spain for instance, the vintager gathers the grapes while the ground beneath is under water; on the other hand, in most parts of the world, it is absolutely necessary to carry off the autumn rains by draining. It is about the rising of the Dog-star that irrigation is so particularly beneficial; but even then it ought not to be in excess, as the roots are apt to become inebriated, and to receive injury therefrom. Care should be taken, too, to proportion it to the age of the tree, young trees being not so thirsty as older ones; those too which require the most water, are the ones that have been the most used to it. On the other hand, plants which grow in a dry soil, require no more moisture than is absolutely necessary to their existence.

CHAP. 41.—REMARKABLE FACTS CONNECTED WITH IRRIGATION.

In the Fabian district, which belongs to the territory of Sulmo[3233] in Italy, where they are in the habit, also, of irrigating the fields, the natural harshness of the wines makes it necessary to water the vineyards; it is a very singular thing, too, that the water there kills all the weeds, while at the same time it nourishes the corn, thus acting in place of the weeding-hook. In the same district, too, at the winter solstice, and more particularly when the snow is on the ground or frosts prevail, they irrigate the land, a process which they call “warming” the soil. This peculiarity, however, exists in the water of one river[3234] only, the cold of which in summer is almost insupportable.

CHAP. 42. (27.)—INCISIONS MADE IN TREES.

The proper remedies for charcoal-blight and mildew[3235] will be pointed out in the succeeding Book.[3236] In the meantime, however, we may here observe that among the remedies may be placed that by scarification.[3237] When the bark becomes meagre and impoverished by disease, it is apt to shrink, and so compress the vital parts of the tree to an excessive degree: upon which, by means of a sharp pruning knife held with both hands, incisions are made perpendicularly down the tree, and a sort of looseness, as it were, imparted to the skin. It is a proof that the method has been adopted with success, when the fissures so made remain open and become filled with wood of the trunk growing between the lips.

CHAP. 43.—OTHER REMEDIES FOR THE DISEASES OF TREES.

The medical treatment of trees in a great degree resembles that of man, seeing that in certain cases the bones of them both are perforated even.[3238] The bitter almond will become sweet, if, after spading round the trunk and cleaning it, the lowermost part of it is pierced all round, so that the humours may have a passage for escape and ensure being removed. In the elm, too, the superfluous juices are drawn off, by piercing the tree above ground to the pith when it is old, or when it is found to suffer from an excess of nutriment. So, too, when the bark of the fig is turgid and swollen, the confined juices are discharged by means of light incisions made in a slanting direction; by the adoption of which method the fruit is prevented from falling off. When fruit-trees bud but bear no fruit, a fissure is made in the root, and a stone inserted; the result of which is, that they become productive.[3239] The same is done also with the almond, a wedge of robur being employed for the purpose. For the pear and the service tree a wedge of torch-wood is used, and then covered over with ashes and earth. It is even found of use, too, to make circular incisions around the roots of the vine and fig, when the vegetation is too luxuriant, and then to throw ashes over the roots. A late crop of figs is ensured, if the first fruit is taken off when green and little larger than a bean; for it is immediately succeeded by fresh, which ripens at a later period than usual. If the tops of each branch are removed from the fig, just as it is beginning to put forth leaves, its strength and productiveness are greatly increased. As to caprification, the effect of that is to ripen the fruit.

CHAP. 44.—CAPRIFICATION, AND PARTICULARS CONNECTED WITH THE FIG.

It is beyond all doubt that in caprification the green fruit gives birth to a kind of gnat;[3240] for when they have taken flight, there are no seeds to be found within the fruit: from this it would appear that the seeds have been transformed into these gnats. Indeed, these insects are so eager to take their flight, that they mostly leave behind them either a leg or a part of a wing on their departure. There is another species of gnat,[3241] too, that grows in the fig, which in its indolence and malignity strongly resembles the drone of the bee-hive, and shows itself a deadly enemy to the one that is of real utility; it is called centrina, and in killing the others it meets its own death.

Moths, too, attack the seeds of the fig: the best plan of getting rid of them, is to bury a slip of mastich,[3242] turned upside down, in the same trench. The fig, too, is rendered extremely productive[3243] by soaking red earth in amurca, and laying it, with some manure, upon the roots of the tree, just as it is beginning to throw out leaves. Among the wild figs, the black ones, and those which grow in rocky places, are the most esteemed, from the fact of the fruit containing the most seed. Caprification takes place most advantageously just after rain.

CHAP. 45.—ERRORS THAT MAY BE COMMITTED IN PRUNING.

But, before everything, especial care should be taken that intended remedies are not productive of ill results; as these may arise from either remedial measures being applied in excess or at unseasonable times. Clearing away the branches is of the greatest benefit to trees, but to slaughter[3244] them this way every year, is productive of the very worst results. The vine is the only tree that requires lopping every year, the myrtle, the pomegranate, and olive every other; the reason being that these trees shoot with great rapidity. The other trees are lopped less frequently, and none of them in autumn; the trunk even is never scraped,[3245] except in spring. In pruning a tree, all that is removed beyond what is absolutely necessary, is so much withdrawn from its vitality.

CHAP. 46.—THE PROPER MODE OF MANURING TREES.

The same precautions, too, are to be regarded in manuring. Though manure is grateful to the tree, still it is necessary to be careful not to apply it while the sun is hot, or while it is too new, or more stimulating than is absolutely necessary. The dung of swine will burn[3246] up the vine, if used at shorter intervals than those of five years; unless, indeed, it is mixed with water. The same is the case, too, with the refuse of the currier’s workshop, unless it is well diluted with water: manure will scorch also, if laid on land too plentifully. It is generally considered the proper proportion, to use three modii to every ten feet square; this, however, the nature of the soil must decide.

CHAP. 47.—MEDICAMENTS FOR TREES.

Wounds and incisions of trees are treated also with pigeon dung and swine manure. If pomegranates are acid, the roots of the tree are cleared, and swine’s dung is applied to them: the result is, that in the first year the fruit will have a vinous flavour, but in the succeeding one it will be sweet. Some persons are of opinion that the pomegranate should be watered four times a year with a mixture of human urine and water, at the rate of an amphora to each tree; or else that the extremities of the branches should be sprinkled with silphium[3247] steeped in wine. The stalk of the pomegranate should be twisted, if it is found to split while on the tree. The fig, too, should be drenched with the amurca of olives, and other trees when they are ailing, with lees of wine; or else lupines may be sown about the roots. The water, too, of a decoction of lupines is beneficial to the fruit, if poured upon the roots of the tree. When it thunders at the time of the Vulcanalia,[3248] the figs fall off; the only remedy for which is to have the area beneath ready covered with barley-straw. Lime applied to the roots of the tree makes cherries come sooner to maturity, and ripen more rapidly. The best plan, too, with the cherry, as with all other kinds, is to thin the fruit, so that that which is left behind may grow all the larger.

(28.) There are some trees, again, which thrive all the better for being maltreated,[3249] or else are stimulated by pungent substances; the palm and the mastich for instance, which derive nutriment from salt water.[3250] Ashes have the same virtues as salt, only in a more modified degree; for which reason it is, that fig-trees are sprinkled with them; as also with rue,[3251] to keep away worms, and to prevent the roots from rotting. What is still more even, it is recommended to throw salt[3252] water on the roots of vines, if they are too full of humours; and if the fruit falls off, to sprinkle them with ashes and vinegar, or with sandarach if the grapes are rotting.[3253] If, again, a vine is not productive, it should be sprinkled and rubbed with strong vinegar and ashes; and if the grapes, instead of ripening, dry and shrivel up, the vine should be lopped near the roots,[3254] and the wound and fibres drenched with strong vinegar and stale urine; after which, the roots should be covered up with mud annealed with these liquids, and the ground spaded repeatedly.

As to the olive, if it gives promise of but little fruit, the roots should be bared, and left exposed to the winter cold,[3255] a mode of treatment for which it is all the better.

All these operations depend each year upon the state of the weather, and require to be sometimes retarded, and at other times precipitated. The very element of fire even has its own utility, in the case of the reed for instance; which, after the reed-bed has been burnt, will spring up all the thicker and more pliable.[3256]

Cato,[3257] too, gives receipts for certain medicaments, specifying the proportions as well; for the roots of the large trees he prescribes an amphora, and for those of the smaller ones, an urna, of amurca of olives, mixed with water in equal proportions, recommending the roots to be cleared, and the mixture to be gradually poured upon them. In addition to this, in the case of the olive and the fig, he recommends that a layer of straw should be first placed around them. In the fig, too, more particularly, he says that in spring the roots should be well moulded up; the result of which is, that the fruit will not fall off while green, and the tree will be all the more productive, and not affected with roughness of the bark. In the same way, too,[3258] to prevent the vine-fretter[3259] from attacking the tree, he recommends that two congii of amurca of olives should be boiled down to the consistency of honey, after which it must be boiled again with one-third part of bitumen, and one-fourth of sulphur; and this should be done, he says, in the open air, for fear of its igniting if prepared in-doors; with this mixture, the vine is to be anointed at the ends of the branches and at the axils; after which, no more fretters will be seen. Some persons are content to make a fumigation with this mixture while the wind is blowing towards the vine, for three days in succession.

Many persons, again, attribute no less utility and nutritious virtue to urine than Cato does to amurca; only they add to it an equal proportion of water, it being injurious if employed by itself. Some give the name of “volucre”[3260] to an insect which eats away the young grapes: to prevent this, they rub the pruning-knife, every time it is sharpened, upon a beaver-skin, and then prune the tree with it: it is recommended also, that after the pruning, the knife should be well rubbed with the blood of a bear.[3261] Ants, too, are a great pest to trees; they are kept away, however, by smearing the trunk with red earth and tar: if a fish, too, is hung up in the vicinity of the tree, these insects will collect in that one spot. Another method, again, is to pound lupines in oil,[3262] and anoint the roots with the mixture. Many people kill both ants as well as moles[3263] with amurca, and preserve apples from caterpillars as well as from rotting, by touching the top of the tree with the gall of a green lizard.

Another method, too, of preventing caterpillars, is to make a woman,[3264] with her monthly courses on her, go round each tree, barefooted and ungirt. Again, for the purpose of preventing animals from doing mischief by browsing upon the leaves, they should be sprinkled with cow-dung each time after rain, the showers having the effect of washing away the virtues of this application.

The industry of man has really made some very wonderful discoveries, and, indeed, has gone so far as to lead many persons to believe, that hail-storms may be averted by means of a certain charm, the words of which I really could not venture seriously to transcribe; although we find that Cato[3265] has given those which are employed as a charm for sprained limbs, employing splints of reed in conjunction with it. The same author,[3266] too, has allowed of consecrated trees and groves being cut down, after a sacrifice has first been offered: the form of prayer, and the rest of the proceedings, will be found fully set forth in the same work of his.
