Chapter XXVI: Section II (4)

So late as July 26, the proportion of water in the stalk was 94 per cent.; and the ash calculated dry 17.66 per cent. The plant gained 21.36.98 grains in weight in a week preceding the 6th September. This was equal to a gain of 12.72 grains per hour.

The rapid growth of corn plants, when the heat, light, and moisture, as well as the soil are favorable, is truly wonderful. A deep, rich, mellow soil, in which the roots can freely extend to a great distance in depth and laterally, is what the corn-grower should provide for his crop. The perviousness of river bottoms contributes largely to their productiveness of this cereal. A compact clay, which excludes alike air, water, and roots, forbidding all chemical changes, is not the soil for Indian corn.

When farmers sell corn soon after it is ripe, there is considerable gain in not keeping it long to dry and shrink in weight. Corn grown by Mr. Salisbury, which was ripe by the 18th October, then contained 37 per cent. of water, which is 25 per cent. more than old corn from the crib will yield. The mean of man experiments tried by the writer has been a loss of 20 per cent. in moisture between new and old corn. The butts of cornstalks contain the most water, and husks or shucks the least, when fully matured and not dried. The latter have about 30 per cent, of dry matter when chemically desiccated.

COMPOSITION OF THE ASH OF THE LEAVES AT DIFFERENT STAGES.

The above figures disclose several interesting facts. It will be seen that the increase of silica or flint in the leaf is steadily progressive from 13½ per cent. at July 19, to 58.65 at October 18.

Flint is substantially the _bone earth_ of all grasses. If one were to analyse the bones of a calf when a day old, again when thirty days of age, and when a year old, the increase of phosphate of lime in its skeleton would be similar to that witnessed in the leaves and stems of maize. In the early stages of the growth of corn, its leaves abound in phosphates; but after the seeds begin to form, the phosphates leave the tissues of the plant in other parts, and concentrate in and around the germs in the seeds. On the 23rd of August, the ash of the whole stalk contained 19½ per cent. of phosphates; and on the 18th of October, only 15.15 per cent. In forming the cobs of this plant, considerable potash is drawn from the stalk, as it decreases from 35.54 per cent. August 16, to 24.69 October 18. When the plant is growing fastest, its roots yield an ash which contains less than one per cent. of lime; but after this development is nearly completed, the roots retain, or perhaps regain from the plant above, over 4½ per cent. of this mineral. Soda figures as high as from 20 to 31 per cent. in the ash obtained from corn roots. Ripe seeds gave the following results on the analysis of their ash:--

Silica 0.850
Phosphoric acid 49.210
Lime 0.075
Magnesia 17.600
Potash 23.175
Soda 3.605
Sodium 0.160
Chlorine 0.295
Sulphuric acid 0.515
Organic acids 5.700
------
99.175

The above table shows a smaller quantity of lime than is usually found in the ash of this grain. It is, however, never so abundant as magnesia; and Professor Emmons has shown that the best corn lands in the State of New York contain a considerable quantity of magnesia. All experience, as well as all chemical researches, go to prove that _potash_ and phosphoric acid are important elements in the organisation of maize. Corn yields more pounds of straw and grain on poor land than either wheat, rye, barley, or oats; and it does infinitely better on rich than on sterile soils. To make the earth fertile, it is better economy to plant thick than to have the rows five feet apart each way, as is customary in some of the Southern States, and only one stalk in a hill. This gives but one plant to twenty-five square feet of ground. Instead of this, three square feet are sufficient for a single plant; and from that up to six, for the largest varieties of this crop.

Mr. Humboldt states the production of maize in the Antilles as 300 for one; and Mr. H. Colman has seen in several cases in the New England States of America, a return of 400 for one; that is to say, the hills being three feet apart each way, a peck of Indian corn would be sufficient seed for an acre. If 100 bushels of grain is in such case produced by an acre--and this sometimes happens--this is clearly a return of 400 for one.

Of the whole family of cereals, _Zea Mays_ is unquestionably the most valuable for cultivation in the United States. When the time shall come that population presses closely on the highest capabilities of American soil, this plant, which is a native of the New World, will be found greatly to excel all others in the quantity of bread, meat, milk, and butter which it will yield from an acre of land. With proper culture, it has no equal for the production of hay, in all cases where it is desirable to grow a large crop on a small surface.

Although there has been much written on the Eastern origin of this grain, it did not grow in that part of Asia watered by the Indus, at the time of Alexander the Great's expedition, as it is not among the productions of the country mentioned by Nearchus, the commander of the fleet; neither is it noticed by Arian, Diodorus, Columella, nor any other ancient author; and even as late as 1491, the year before Columbus discovered America, Joan di Cuba, in his "Ortus Sanitatis," makes no mention of it. It has never been found in any ancient tumulus, sarcophagus, or pyramid; nor has it ever been represented in any ancient painting, sculpture, or work of art, except in America. But in that country, according to Garcilaso de la Vega, one of the ancient Peruvian historians, the palace gardens of the Incas, in Peru, were ornamented with maize, in gold and silver, with all the grains, spikes, stalks, and leaves; and in one instance, in the "garden of gold and silver," there was an entire cornfield, of considerable size, representing the maize in its exact and natural shape; a proof no less of the wealth of the Incas, than their veneration for this important grain.

In further proof of the American origin, it may be stated that this plant is still found growing, in a wild state, from the Rocky mountains in North America, to the humid forests of Paraguay, where, instead of having each grain naked, as is always the case after long cultivation, it is completely covered with glumes or husks. It is, furthermore, a well authenticated fact, that maize was found in a state of cultivation by the aborigines, in the island of Cuba, on its discovery by Columbus, as well as in most other places in America, first explored by Americans.

The first successful attempt to cultivate this grain in North America, by the English, occurred on James' river, in Virginia, in 1608. It was undertaken by the colonists sent over by the Indian company, who adopted the mode then practised by the natives, which, with some modifications, has been pursued throughout this country ever since. The yield, at this time, is represented to have been from two hundred to more than one thousand fold. The same increase was noted by the early settlers in Illinois. The present yield, east of the Rocky Mountains, when judiciously cultivated, varies from 20 to 135 bushels to an acre.

The varieties of Indian corn are very numerous, exhibiting every grade of size, color, and conformation, between the "chubby reed" that grows on the shores of Lake superior--the gigantic stalks of the Ohio valley--the tiny ears, with flat, close, clinging grains, of Canada--the brilliant, rounded little pearl--the bright red grains and white cob of the eight-rowed hæmatite--the swelling ears of the big white and the yellow gourd seed of the South. From the flexibility of this plant, it may be acclimatised, by gradual cultivation, from Texas to Maine, or from Canada to Brazil; but its character, in either case, is somewhat changed, and often new varieties are the result. The blades of the plant are of great value as food for stock, and is an article but rarely estimated sufficiently, when considering of the agricultural products of the Southern and Southwestern States especially.

To supply slaves on plantations with bread, including old and young, requires from twelve to thirteen bushels of corn each a year. Taking thirteen bushels as the average consumption of breadstuffs by the 22,000,000 of people in the United States, the aggregate is 286,000,000 bushels per annum.

The increase of production, from 1840 to 1850, was 214,000,000 bushels, equal to 56 per cent.

The production of New England advanced from 6,993,000 to 10,377,000 bushels, showing an increase of 3,384,000 bushels, nearly fifty per cent. New York, New Jersey, Pennsylvania, Delaware and Maryland, increased 20,812,000 bushels, more than fifty per cent. In the production of this crop no State has retrograded. Ohio, which in 1840 occupied the fourth place as a corn-producing State, now ranks as the first. Kentucky is second, Illinois third, Tennessee fourth. The crop of Illinois has increased from 2,000,000 to 5,500,000 bushels, or at the rate of 160 per cent. in ten years.

Of the numerous varieties some are best adapted to the Southern States, while others are better suited for the Northern and Eastern. Those generally cultivated in the former are the Southern big and small yellow, the Southern big and small white flint, the yellow Peruvian, and the Virginian white gourd seed. In the more Northerly and Easterly States they cultivate the golden sioux, or Northern yellow flint, the King Philip, or eight-rowed yellow, the Canadian early white, the Tuscarora, the white flour, and the Rhode Island white flint.

The extended cultivation of this grain is chiefly confined to the Eastern, Middle, and Western States, though much more successfully grown in the latter. The amount exported from South Carolina, in 1748, was 39,308 bushels; from North Carolina, in 1753, 61,580 bushels; from Georgia, in 1755, 600 bushels; from Virginia, for several years preceding the revolution, annually 600,000 bushels; from Philadelphia, in 1765-66, 54,205 bushels; in 1771, 259,441 bushels.

The total amount exported from America in 1770, was 573,349 bushels; in 1791, 2,064,936 bushels, 351,695 of which were Indian meal; in 1800, 2,032,435 bushels, 338,108 of which were in meal; in 1810, 1,140,960 bushels, 86,744 of which were meal. In 1820-21, there were exported 607,277 bushels of corn, and 131,669 barrels of Indian meal; in 1830-31, 571,312 bushels of corn, and 207,604 barrels of meal; in 1840-41,535,727 bushels of corn, and 232,284 barrels of meal; in 1845-46, 1,286,068 bushels of corn, and 298,790 barrels of meal; in 1846-47 16,326,050 bushels of corn, and 948,060 barrels of meal; in 1850-51, 3,426,811 bushels of corn, and 203,622 barrels of meal. More than eleven millions of bushels of Indian corn were consumed in 1850, in the manufacture of spirituous liquors.

According to the census of 1840, the corn crop of the United States was 377,531,875 bushels; in 1850, 592,326,612 bushels.

The increase in the production of corn in Ohio has been (in ten years) 66 per cent. I have also before me the auditor's returns for the crop of 1850, as taken by assessors, and the number of acres planted. The auditor's returns are:--

Seventy-three counties 55,079,374
Darke county 524,484
Twelve counties, average 8,400,000
----------
Total 64,003,858

This is an advance of 15 per cent. on the crop of 1840, and it is known that the crop of 1850 was better than that of 1849. The number of acres planted, and the average production was:--

Acres planted 1,810,947 Bushels produced 64,003,858 Average per acre 35-3/8 bush.

Considering how large a portion of hill land is planted, and how many fields are ill cultivated, the average is high. Many persons have believed that taking all years and all lands into view, the average of corn lands was not more than thirty bushels. But the immense fertility of _bottom_ lands on the rivers and creeks of Ohio make up for bad cultivation and inferior soil. We may see something of the differences in the production of corn, by taking the averages of different counties, thus:--

Acres. Crop. Average.
Butler 62,031 2,646,353 42½
Warren 42,322 1,757,409 42
Pickaway 65,860 2,627,727 40
Ross 69,520 2,918,958 42

Compare the average of these counties, which embrace some of the best lands in the State, with the following:--

Acres. Crop. Average.
Carroll 10,107 316,999 32
Jackson 15,680 439,850 30
Monroe 23,375 728,242 31
Portage 10,426 329,529 32
Vinton 11,413 345,470 30

The last counties contain but little bottom land, and hence the average of corn is reduced one-fourth in amount. Of these counties, two are full of coal and iron. The resources of the last are more slow to develop, but in the end will be equally valuable.

But a small quantity of the corn of Ohio is exported _as grain_. It is first manufactured into other articles, and then exported in another form. The principal part of these are hogs, cattle, and whiskey. It is difficult to say exactly how much corn is _in this way exported_, but the following is an approximation--

Bushels.
In Fat Cattle 4,000,000
In Fat Hogs 10,000,000
In Whiskey 2,500,000
----------
Total 16,500,000

Taking into view the export of corn meal--about twenty millions of bushels--the residue goes to the support of the stock animals on hand, of which there are near three millions, exclusive of those fatted for market.

The exported corn in the shape of cattle, hogs, and whiskey, is worth about thirty cents cash, while on the farm it is not worth twenty--thus proving that it is more profitable to consume corn on the farm, than to export it in bulk. This fact is well known to good farmers, who seldom attempt to sell corn as a merchantable article.

No mining in the world has ever been equal to mining in a fertile soil, and no treasury is so reliable as a granary of surplus products.

Indian corn and meal generally find a market in the West Indies, Newfoundland, Spain, and Portugal. It commands a good price, and finds a ready sale in the ports which are open to its reception.

Deducting one-sixteenth for the amount exported, and one-tenth for seed, the quantity of maize annually consumed for food in the United States by a family of five persons is 85 bushels.

Maize may be considered as the great staple of the agricultural products of the States. It is exported in large quantities, in a raw state, or when manufactured into meal. Before it is manufactured into meal it is dried by a fire, in a kiln prepared for that purpose. By this process the meal is much less liable to become sour on the voyage, and can be preserved much longer in a warm climate. No inconsiderable quantities have likewise been consumed in distillation; and the article of kiln-dried meal for exportation is destined to be of no small account to the corn-growing sections of that country.

The improvement continually making in the quality of the seed augurs well for the productiveness of this indigenous crop, as it has been found that new varieties are susceptible of being used to great advantage.

The following was the produce of the different States in the years named, as given in the Official Census Returns:--

The Indian corn crop of 1850, for the whole of the United States, is returned as over 500 million bushels, a gain of about 40 millions on that of 1840.

I give below the quantities of Indian corn and meal which were exported from the United States in the following years:--

--(_Pitkin's Statistics of the United Stales, and Seybert's
Statistical Annals_.)

_System of culture pursued in the United States_.--Maize, the _corn, par excellence_, of America, is grown in every State in the Union.

Tennessee, Kentucky, Ohio, Virginia, and Indiana, are in their order the greatest producers of this grain. In Illinois, North Carolina, Georgia, Alabama, Missouri, Pennsylvania, South Carolina, New York, Maryland, Arkansas, and the New England States, it appears to be a very favorite crop. In Massachusetts, the most Northern and least favorable State on that account, being cold, a fair proportion is grown, the aggregate produce being greater there than in any of the grains, except oats; more, indeed, than might be expected, were not labor somewhat cheaper than in more Southern States, where the climate is more congenial. The ordinary produce is twenty-five bushels per acre; forty bushels is often raised, and in prize crops the weight has come up to 100 bushels per acre. In Ohio the average is fifty-five bushels to the acre. The eight and twelve-rowed varieties of Indian corn are those most usually grown in New York, and the average produce of a good field in that State is from forty to sixty bushels; on ordinary ground twenty-five to thirty is a fair crop. The same returns appeared to be derived from ground in New Jersey. Mr. Doubleday, of Binghampton, New York, estimates the produce of that neighbourhood at forty bushels, and the expense of raising the crop as follows, estimating the worth of the land at twenty-five dollars (say £5) per acre:--

Dollars. Cents.
The interest of which is 1 16
One ploughing with double team, and harrowing 3 50
Seed and planting 1 00
Plaster or gypsum, and putting on the hill 0 37
Ploughing and hoeing twice, cutting
or stalking the corn 2 75
Husking or thrashing 2 50
-----------------
11 62

Average yield, forty bushels; cost of produce, twenty-nine cents. (1s. 4½d.) per bushel.

Nothing is here put down for manure or cartage, because the fodder, cut up and saved, as usually adopted, is equal to the manure required. It is looked upon that the preparation of ground for corn costs less than wheat; the approved plan is to plant on sward ground, ploughing at once, and turning the ground completely over, then harrowing longitudinally until, a good tilth is obtained. Should the soil not be rich enough, stable manure is first spread on the land.

Now suppose the corn to sell at seventy-five cents the bushel, the account would stand thus:--

Dollars. Cents.
Forty bushels, at seventy-five cents. 30 00
Cost 11 62
---------------
Gain per acre 18 38

or £3 13s. 6d. British money profit per acre.

In Lichfield, Connecticut, the cost of produce has been, for the items as stated above, eighteen dollars twenty-five cents, or the cost of each bushel thirty-six and one-half cents. The acre produce was fifty bushels, so that it stood thus:--

Dollars. Cents.
Fifty bushels, at seventy-five cents 37 50
Cost 18 25
-----------------
Gain 19 5

or £3 12s. per acre.

The cost of producing maize varies somewhat in the other States, thus:--

Per bushel.
Cents.
New Hampshire (Unity) the cost was 50
Fayette county, Pennsylvania 16 ¼
Donesville, Michigan, only 17 ½
Plymouth, Massachusetts 17 7/10

The cost on producing this crop was small, but it appears to have been a small crop, and did not bring more than thirty cents per bushel.

In Monroe county, the richest land in the State of New York, estimating the land at fifteen dollars per acre, the producing cost stood at:--

Dollars. Cents.
Interest at six per cent. 0 45
One ploughing sward, cover or stubble 1 00
Harrowing, furrowing, seed, and planting 0 87½
Cultivating three times and hoeing 1 00
Husking the hill 1 00
Shelling and cleaning 1 00
---------------
5 82½

This yielded fifty bushels, the cost of producing the bushel was eleven and three-fifths cents. This low cost was owing to the fact of no manure being used; and while it speaks volumes as to the natural fertility of American soils, yet it reflects very disgracefully upon the careless system adopted there, as under such treatment no land could continue, after some years, to produce a crop which could come into competition with those from newer and less exhausted lands; but if under a good system of tillage the ground was yearly renewed with manure, and those amendments which every soil requires, after a crop has been raised from it, added to the soil in top-dressing and in ploughing-in, we should never hear of the exhausted state of New England land, or see the sons of the soil moving west and cultivating newer soils, thus removing much of the capital and intelligence of a country away from it.

Supposing the corn of Monroe county sold at seventy cents per bushel, the balance would appear thus:--

Dollars. Cents.
Fifty bushels, at seventy cents 35 00
Cost of production 5 82½
--------------
Gain 29 18½

£6 1s. per acre profit.

In Northern Ohio and in Illinois the cost of production averages twenty cents per bushel.

The mode of cultivation in Connecticut and the New England States has been thus described to me by Mr. L. Durand, an experienced agriculturist:--If the soil selected is light and mellow, it should be ploughed and subsoiled in the spring, first spreading on the coarse unfermented manure which is to be ploughed in. For marking the rows for planting, a "corn marker" may be used to advantage. It is made by taking a piece of scantling, three inches square and ten to twelve feet long, with teeth of hickory or white oak inserted at distances of two to four feet, according to the width designed for the rows. Then an old pair of waggon-thills and a pair of old plough-handles are put to it, and your marker is done. With a good horse to draw this implement, the ground may be made ready for planting very rapidly. It is better to leave the ground flat than to ridge it, for the latter mode has no advantage, except when the ground is wet. The difference in the two modes is chiefly this:--When the ground is ridged, the corn being planted between the edges of the furrows, it comes immediately in contact with the manure, springs up and grows rapidly the fore part of the season. When the ground is left flat, and the manure turned under the furrows, the corn will often look feeble at first, and in growth will frequently be much behind that on the ridges; and the inference early in the season is, that the ridged ground will give the best crop, but as soon as the roots of the corn on the flat ground get hold of the manure (say about the 20th of July), the corn will shoot rapidly ahead, and the full force of the manure will be given to the stalk just at the time of forming the grain. Corn cultivated in this way, if the soil is deeply tilled, will often keep green, while that on ridges is dried up.

Many farmers, at planting, shell the corn off the cob, and plant it dry. Others soak it a few days in warm water. But when the seed is only treated in this way, it is very likely to be pulled up by birds and injured by worms. The best way to prevent this is to first soak the corn in a strong solution of saltpetre; then take a quantity of tar, and having warmed it over a fire, pour it on the corn, and stir with a stick or paddle till the grain is all smeared with the tar; then add gypsum or plaster till the corn will separate freely, and no birds will touch the grain.

The time of planting, in the United States, varies with the season and the section of the country. In New England it may generally be planted from the 15th to the 25th May. Where the ground is flat, a light harrow or a cultivator is much better to go between the rows than the plough. Formerly a great deal of useless labor was spent in hilling up corn; in dry seasons this was worse than useless. The earth hauled round the stalk does not assist its growth, nor aid in holding it up; the brace roots, which come out as the stalk increases in height, support it; and it has been observed, that in a heavy storm and thunder gust, corn that is hilled will be broken down more than that which is not hilled. The ground which is kept level has also the advantage of more readily absorbing rain, rendering the crop less liable to suffer from drought. The field should have two or three regular hoeings, and the weeds be carefully kept under.

In harvesting the following will be found a good plan:--Let two hands take five rows, cutting the corn close to the ground. A hill should be left standing to form the centre of the shock, placing the stalks round it, so that they may not lie on the ground. After the shock is made of sufficient size, take a band of straw, and having turned down the tops of the stalks, bind them firmly, and the work is done.

Maize may be cut as soon as the centre of the grain is glazed, even if the stalks are green. There will be sufficient nutriment in the stalk to perfect the ear, and the fodder is much better than when it gets dry before it is cut. If the shocks are well put up, they may stand four or five weeks. The corn may then be knocked out, and the fodder secured for winter use.

The report of the Ohio Board of Agriculture for 1849, contains many interesting statements in reference to maize culture, made by the officers of numerous county agricultural societies. In Miami county, 2,030,670 bushels were grown, at an average yield of fifty-five bushels per acre. Three varieties are cultivated: the common gourd seed, for cattle; the yellow Kentucky, for hogs and distilling; and the white, for grinding and exportation. According to the returns from Green county, which produced 1,250,000 bushels of corn in 1849, "a regular rotation of clover, corn, wheat, and clover again, is best for corn; and no crop pays better for extra culture." The Harrison county Agricultural Society reports the pork crop at 4,800,000 pounds; and it gave its first premium for corn to Mr. S.B. Lukens, whose statement is as follows:--

"The ground had been in meadow ten years, was ploughed six inches
deep about the middle of April, was harrowed twice over on the 9th
May, and planted on the 11th four feet by two feet. It came up well,
was cultivated and thinned when ten inches high; three stalks were
left in a hill. About two weeks afterward it was again cultivated,
and the suckers pulled off. About the last of June it was again
cultivated, making three times the same way, as it was laid off but
one way.

d. c.
Expense of culture, gathering, and cribbing, was 17 10
Produce of 374-3/8 bushels, at 31¼ cents 117 10
----------
Profit on three acres 100 00

The evidence on which a premium was awarded was such as should satisfy any one that 374 bushels were grown on three acres of land, and at a cost not exceeding 17 dollars 10 cents, delivered in the crib. This is producing corn at less than 5 cents a bushel.

Whether the statement be true to the letter or not, it shows conclusively the great value of a _rich soil_ for making cheap corn. The Board of Agriculture estimates the crop of Ohio last year at 70,000,000 of bushels. Taking the United States as a whole, probably the crop of corn was never better than in the year 1849. One that has rich land needs only to plough it deep and well, plant in season, and cultivate the earth properly with a plough or cultivator, to secure the growth of a generous crop. On poor soils the case is very different.

To raise a good crop of corn on poor land, and at the least possible expense, requires some science and much skill in the art of tillage. Take the same field to operate in, and one farmer will grow 100 bushels of corn at half the cost per bushel that another will expend in labor, which is money. It unfortunately happens that very skilful farmers are few in number, in comparison with those who have failed to study and practice all attainable improvements. To produce cheap corn on poor land, one needs a clear understanding of what elements of the crop air and water will furnish, and what they cannot supply. It should be remembered that the atmosphere is precisely the same over ground which yields 100 bushels of corn per acre, that it is over that which produces only five bushels per acre. Now, the whole matter which forms the stems, leaves, roots, cobs, and seeds of corn, where the crop is 100 bushels per acre, is not part and parcel of the soil. A harvest equal to fifty bushels per acre can be obtained without consuming over ten per cent, of earth, as compared with the weight of the crop. No plant can imbibe more of the substance of the soil in which it grows, than is dissolved in water, or rendered gaseous by the decomposition of mould.

The quantity of matter dissolved, whether organic or inorganic, during the few weeks in which corn plants organise the bulk of their solids, is small. From 93 to 97 parts in 100 of the dry matter, in a mature, perfect plant, including its seeds, cob, stems, leaves, and roots, are carbon (charcoal) and the elements of water. It is not only an important, but an exceedingly instructive fact, that the most effective fertilisers known in agriculture are those that least abound in the elements of water and carbon. The unleached dry excrements of dunghill fowls and pigeons, have five times the fertilising power on all cereal plants that the dry dung of a grass-fed cow has, although the latter has five times more carbon, oxygen, and hydrogen, per 100 pounds, than the former. Although it is desirable to apply to the soil in which corn is to grow as much of organised carbon and water as one conveniently can, yet, where fertilisers have to be transported many miles; it is important to know that such of the measure as would form _coal_, if carefully burnt, can best be spared. The same is true of those elements in manure which form vapor or water, when the fertiliser decomposes in the ground.

Carbonic acid and nascent hydrogen evolved in rotting stable manure are truly valuable food for plants, and perform important chemical offices in the soil; but they are, nevertheless, not so indispensable to the economical production of crops, as available nitrogen, potash, silica, magnesia, sulphur, and phosphorus. These elements of plants being less abundant in nature, and quite indispensable in forming corn, cotton, and every other product of the soil, their artificial supply in guano, night soil, and other highly concentrated fertilisers, adds immensely to the harvest, through the aid of a small weight of matter. In all sections where corn is worth 30 cents and over a bushel, great benefits may be realised by the skilful manufacture and use of poudrette. This article is an inodorous compound of the most valuable constituents of human food and clothing. It is the raw material of crops.

It is not necessary to restore to a cornfield all the matter removed in the crop to maintain its fertility. A part of each seed, however, ought to be carried back and replaced in the soil, to make good its loss by the harvest.

In every barrel of meal or flour sent to market (196 pounds), there are not far from 186 pounds of carbon (coal), and the elements of water. When a bird eats wheat or corn, I have reason to believe, from several experiments, that over 80 per cent, of the food escapes into the air through its capacious lungs in the process of respiration; and yet the 20 per cent, of guano left will re-produce as much wheat or corn as was consumed. Imported guano, which has been exposed to the weather for ages, often gives an increase in the crop of wheat equal to three pounds of seed to one of fertiliser; while it has given a gain of seven to one of corn, and fifty to one of green turnips.

Like other grains that have been long cultivated, Indian corn abounds in varieties. In Spain they count no less than 130, and in the United States the number is upwards of forty. The difference consists in size, color, period of maturation, and hardness and weight of grain. Of size there exists a considerable variety, from Zea Curagua of Chili, and the Egyptian or chicken corn, both extremely diminutive, to the large white flint, and ground seed corn of the United States. The differences in color are the red, yellow, and white. The period of maturation varies, apparently, very considerably; but it is questionable whether this variation is real, and independent of climate. In the Northern States of America, Indian corn ripens in a shorter period of time than it does in the South, owing, possibly, to the greater length of the summer day in those latitudes.

In selecting varieties, some experienced and judicious farmers prefer that which yields the greater number of ears, without regard to their size, or number of rows. Others prefer that which furnishes one or two larger ears, having from twelve to twenty-four rows. In the Northern States of America the yellow corn bears the highest price in the market, and is considered the most prolific and best suited to feed cattle and hogs. For bread, the white Button is preferred at the North, and the white ground seed is used for that purpose in other quarters. Preference, however, is most frequently given to white flint corn, which is unquestionably the heaviest, and contains the greatest proportion of farina.

In Mississippi many varieties are grown, principally those known as flint and bastard flint. The gourd-seed varieties are very objectionable in that climate, principally on account of their softness rendering them unfit for bread, and open to the attacks of insects in the field and the crib. They require a grain, _white_, _hard_, and rather flinty--_white_ because of its great consumption in bread and hommony, in the preparation of both of which their cooks greatly excel. When meal is ground for bread, the mill is set rather wide, that the flinty part of the grain may not be cut up too fine, this being sifted out for "small hommony;" the farinaceous part of the grain is left for bread. This hommony is a beautiful and delicious dish. On most plantations the negroes have it for supper, with molasses or buttermilk. A _hard flinty_ grain is necessary to head the weevil, with which not only the cribs but the heads of corn in the field are infested. These are the _Calandra oryzæ_, the true rice weevil, distinguished from his European cousin by the two reddish spots on each _elytra_ or wing-cover, and known in America as the "black weevil;" also a little brown insect, not a true weevil, but a _Sylvanus_. This sylvanus, and another of the same genus, most probably the _S. surinamensis_, attack the corn in the field before it becomes hard, causing serious damage--but nothing to equal that occasioned by the black weevil.

I know of no generally successful method of staying or even checking the injury caused by the insects, though much might be written in the way of suggestion.

In Michigan, the _dent_ variety in dry seasons produces the best crops on sandy loam, as its roots run deeper than the common _eight-rowed_ yellow or white. In moist seasons the latter varieties usually do well. They are grown most generally in the Northern part of the State, while in the Southern section the Ohio dent is principally raised. The shuck and blade are much used as fodder for cattle, in the early part of winter.

Indian corn is very liable to change of character from soil and climate, growing smaller the farther North it is raised. The mixing of the eight-rowed yellow with the Ohio dent has, so far as my experience goes, been beneficial in increasing the yield. Sandy loam, or clay, is considered the soil best adapted to corn. It is usually planted in May, and harvested in September. The blade is not taken off there as at the South; some farmers cut up their corn when ripe, put it into shocks, and husk it late in the fall; others cut the stalks, bind them in sheaves, and stack them for winter in the fields, or put them away in barns or sheds; while others husk the corn on the hill without cutting the stalks, and late in the fall turn their cattle into the field to eat the fodder. Of these different modes the preference is usually given to cutting the stalks and putting them under cover after being well cured, and busting the corn on the hill. The corn is thought to ripen better in this way, and to keep better in the cribs. The Ohio dent, having a smaller ear containing less moisture than other varieties, ripens quicker and keeps better. This crop ranges from 25 to 65 bushels per acre, and the difference in the yield is to be attributed to the manner of cultivation. My experience shows that a crop of 45 bushels per acre costs 13 cents a bushel, including interest on land. Corn is principally raised in Michigan for home consumption, and the stalks and shucks, if well cured, are worths dollars per acre, compared with hay at 5 dollars per ton.

As much as 134 bushels per acre have been obtained, in some instances, in Massachusetts; till the last 20 years 35 bushels was considered an average crop, but by a due rotation of crops, and ploughing in long manure, at least 75 bushels to the acre are now raised. The kinds preferred there, are an eight-rowed variety, procured originally from Canada; the Cass corn, another eight-rowed variety, and the Dutton corn, each of which averages about 60 lbs. to the bushel.

Maize is a principal crop in the Connecticut River Valley, Western Vermont, and along the Lake shore; but in the high dividing ridge, and in the Northern counties bordering on Canada, the climate is too severe for its profitable cultivation.

"The kind mostly grown (observes Mr. Colburn, of Vermont) is the
yellow eight-rowed, though some prefer the twelve and sixteen-rowed,
known here by the name of the Button corn; but my experience in
cultivating the different kinds for the last twenty-four years, has
forced me to the conclusion that the common eight-rowed, mixed with
a kind called the Brown corn, does the best; the kernel of
the-latter bearing upon a chocolate hue, and the mixture of these
two kinds of seed imparting a deep rich color to the whole, when
they become blended, and enhancing the yield whenever the soil is in
high tilth. Of this kind, the writer has raised, the past season,
upon eleven acres on the Connecticut River alluvium, over eight
hundred bushels shelled corn, four acres of which, with extra
preparation, produced four hundred and sixteen bushels.

It will never do to carry seed corn from South to North, as it will
not mature in a higher or colder climate than that from which it has
been taken. Even half a degree of latitude sensibly affects the
maturing of the blade, and renders it an uncertain crop in our high
northern latitudes. To insure an extra yield of this valuable grain,
the soil must be highly manured, deeply ploughed, thorough
cultivated and hoed, and top-dressed with lime, house ashes, and
plaster. This done, it is the most remunerative and profitable of
all grain crops."

In Delaware there are many varieties, and everybody esteems his own kind the best. The grain varies from pure "flint" to pure "gourd seed"--of course the mixtures which are between these two varieties are most common--it inclines more to gourd seed than to flint. Mint weighs full standard fifty-six, the gourd seed from forty-nine to fifty-two pounds, and the mixtures range between. Flint ripens from ten days to two weeks earlier. It will not produce as many pounds per acre as the lighter gourd seed. Soil exerts its influence over the character of corn, a heavy soil tending to produce flint--light soil, gourd seed.

The corn is "cut up" in the fall, and after curing in the shuck, is husked; the shuck remaining on the stalk with the blades.

The average yield, on improved land, is fifty bushels; though crops of one hundred and twelve, and one hundred and sixty bushels per acre are reported to have been raised in the county, in 1849. The yield increases from year to year. A general and rapid improvement of the State is in progress, and in nothing is this seen more clearly than in the corn crop. Mossy "old sedge" fields, which have been laid out for years, are broken up, and will yield, if it be a good season, from five to ten bushels per acre; fence them, lime them with twenty to thirty bushels, and seed the oat crop with clover, and in two years the clover sod will return eighteen to twenty bushels of corn. Another dressing of lime, or its equivalent in marl, of which there is an abundance in the lower half of Newcastle County, will show thirty bushels of corn; and of wheat, if the farm manure be used on it, nine to twelve bushels will not be too much to expect.

In Arkansas, Indian corn is regarded as the "king of grains." It constitutes the chief food of every animal, from man down to the marauding rat, while its dried blade furnishes seven-tenths of the long food for working animals. The _large white_ is the variety most esteemed, and most generally cultivated, for the reasons that it yields more grain and fodder, makes, when ground into meal, whiter and sweeter bread, and is less liable to injury from the weevils. The blade is usually esteemed the best long food for horses, exceeding in price the best Northern hay; the average price may be stated at about seventy cents per cwt. The shuck is fed to cows and young mules, they eat it, but with less relish than they do the blades, which are sweeter and more nutritious. The former are much used for mattresses, being preferred to moss, as they are cleaner, and easier manufactured. When mixed with coarse cotton, and properly prepared, they will make a mattress but little inferior to curled hair: price about fifty cents per cwt. The average price of this grain may be set down at forty cents per bushel; and the yield on upland in some parts of the State may be stated at thirty bushels per acre.

Five varieties of maize are grown in Peru. One is known by the name of _chancayano_, which has a large semi-transparent yellow grain; another is called _morocho_, and has small yellow grain of a horny appearance; _amarello_, or the yellow, has a large yellow opaque grain, and is more farinaceous than the two former varieties; _blanco_, white--this variety is large, and contains more farina than the former; and _cancha_, or sweet maize. The last is only cultivated in the colder climates of the mountains; it grows about two feet high, the cob is short, and the grains large and white; when green, it is very bitter, but when ripe and roasted, it is particularly sweet, and so tender that it may be reduced to flour between the fingers. In this roasted state it constitutes the principal food of the mountaineers of several provinces.

The natives remove the husk from the maize by putting it into water with a quantity of wood ashes, exposing it to a boiling heat, and washing the grain in running water, when the husk immediately separates from the grain.

In Jamaica I found maize to produce two crops in the year, and often three. It is usually grown there on the banks or ridges of the cane fields. It may be planted at any time when there is rain, and it yields from fifteen to forty bushels per acre, according to the richness of the soil, and the more or less close manner in which it is planted.

In the colony of New South Wales, including the district of Port Phillip, there were 20,798 acres under cultivation with maize in 1844, the produce from which was returned at 575,857 bushels; 27,058 bushels of maize were exported from Sydney in 1848.

_Culture in the East Indies_.--The growers on the hills of Nepaul reckon three kinds of maize: a white grained species, which is generally grown on the hill sides; a yellow grained one, grown in the low and hot valleys; and a smaller one, called "Bhoteah," or "Murilli Makii," which is considered the sweetest of the three, but from being less productive is not generally grown on good lands. Maize thrives best on a siliceous, well-drained, rich soil. A correspondent in my "Colonial Magazine," vol. ii. p. 309, says the finest Indian corn he ever saw was in the Himalayas of the Sikim-range, where the soil consists of a substratum of decomposed _mica_ from the under or rocky stratum, with a superstratum of from three to six inches of decayed vegetable matter, from leaves, &c., of the ancient forests.

Throughout Hindostan, June is the usual time for sowing. In Behar, about two seers are usually sown upon a beggah; in Nepaul, twenty-four seers upon an English acre; in the vicinity of Poonah, one and a-half seer per beggah. Before the seed is sown the land is usually ploughed two or three times, and no further attention given to the crop than two hoeings. In Nepaul, where it is the principal crop cultivated, the seed is sown, after one delving and pulverisation of the soil, in the latter end of May and early part of June, in drills, the seeds being laid at intervals of seven or eight inches in the drills, and the drills an equal space apart. The drills are not raised as for turnip sowing, but consist merely of rows of the plant on a level surface. The seed is distributed in this manner with the view of facilitating the weeding of the crop, not for the purpose of earthing up the roots, which seems unnecessary. The Indian corn sowing resembles that of the _gohya_ (or upland) rice, in the careful manner in which it is performed; the sower depositing each grain in its place, having first dibbled a hole for it five or six inches deep, with a small hand hoe, with which he also covers up the grain.

The after-culture of this crop is performed with great care in the valleys, but much neglected in the hills, especially on new and strong lands. In the former it undergoes repeated weeding during the first month of its growth, the earth being loosened round the roots, at each weeding, with the hand hoe. After the first loosening of the soil, which is performed as soon as the plants are fairly above ground, a top dressing of ashes or other manure is given. By this mode the crop gets the immediate benefit of the manure, which otherwise, from the extraordinary rapidity of its growth, could not be obtained by it. In three months from the time of sowing, the seed is ripe. The crop is harvested by cutting off the heads. In Nepaul these are either heaped on a rude scaffolding, near the cultivator's house, or, more commonly, they are suspended from the branches of the trees close by, where, exposed to wind and weather, the hard and tough sheath of the seed cones preserves the grain for many months uninjured.

Cattle are voraciously fond of the leaves and stems, which are very sweet, and even the dry straw, which Dr. Buchanan surmises may be the reason why it is not more generally cultivated by the natives, as the difficulty would be great to preserve the crop. So slow is the progress of changes in the regions of India, that near Kaliyachak, though the people give all other straw to their cattle, yet they burn that of maize as unfit for fodder. In Nepaul the stalks, with the leaves attached, often twelve feet long, cut by the sickle, are used as fodder for elephants, bedding for cattle, and as fuel. The maize crop within the hills of Nepaul suffers much from the inroads of bears, which are very numerous in these regions, and extremely partial to this grain. The average return from this crop is seldom below fifty seers, ranging frequently far above it.[42] Maize is increasing in cultivation in Java, and some of the Eastern islands. It is found to have the advantage there over mountain rice, of being more fruitful and hardy, and does not suffer from cold until the mean temperature falls to 45 deg. of Fahrenheit, and no heat is injurious to it. Several varieties of it are known, but for all practical purposes these resolve themselves into two kinds: one, a small grain, requiring five months to ripen, and a larger one, which takes seven to mature. In some provinces of Java it yields a return of 400 or 500 fold. Mr. Crawfurd found, from repeated trials, that in the soil of Mataram, in Java, an acre of land, which afforded a double crop, produced of the smaller grain 848½ lbs. annually.

RICE.

This is one of the most extensively diffused and useful of grain crops, and supports the greatest number of the human race. The cultivation prevails in Eastern and Southern Asia, and it is also a common article of subsistence in various countries bordering on the Mediterranean. It is grown in the Japan Islands, on all the sea coasts of China, the Philippine and other large Islands of the Indian Archipelago, partially in Ceylon, Siam, India, both shores of the Red Sea, Egypt, the shores of the Mozambique Channel, Madagascar, some parts of Western Africa, South Carolina, and Central America. Three species only are enumerated by Lindley:--_Oryza sativa_, the common rice, a native of the East; _O. latifolia_, a species having its habitat in South America; and _O. Nepalensis_, common in Nepaul. But there are a host of varieties known in the East; these, however, may for all practical purposes, be resolved into two kinds--the upland or mountain rice (_O. Nepalensis_, the _O. mutica_, of Roxburgh), and the lowland or aquatic species (_O. sativa_).
