The following is the mode of culture for rice in Carolina:—It is sowed as soon as it conveniently can be after the vernal equinox, from which period until the middle, and even the last of May, is the usual time of putting it in the ground. It grows best in low marshy land, and should be sowed in furrows twelve inches asunder; it requires to be flooded, and thrives best if six inches under water; the water is occasionally drained off, and turned on again to overflow it, for three or four times.
When ripe the straw becomes yellow, and it is either reaped with a sickle, or cut down with a scythe and cradle, some time in the month of September; after which it is raked and bound, or got up loose, and threshed or trodden out, and winnowed in the same manner as wheat or barley.
Husking it requires a different and particular operation, in a mill made for that purpose. This mill is constructed of two large flat wooden cylinders, formed like mill-stones, with channels or furrows cut therein, diverging in an oblique direction from the centre to the circumference, made of a heavy and exceedingly hard timber, called lightwood, which is the knots of the pitch pine. This is turned with the hand, like the common hand-mills. After the rice is thus cleared of the husks, it is again winnowed, when it is fit for exportation.
A bushel of rice will weigh about sixty or sixty-six pounds, and an acre of middling land will produce twenty-five bushels.
Various machines have been contrived for cleaning rice, of which one secured by patent to Mr. M. Wilson, in 1826, and thus described by Dr. Ure, may be regarded as a fair specimen:—It consists of an oblong hollow cylinder, laid in an inclined position, having a great many teeth stuck in its internal surface, and a central shaft, also furnished with teeth. By the rapid revolution of the shaft, its teeth are carried across the intervals of those of the cylinder, with the effect of parting the grains of rice, and detaching whatever husks or impurities may adhere to them. A hopper is set above to receive the rice, and conduct it down into the clean cylinder. About eighty teeth are supposed to be set in the cylinder, projecting so as to reach very nearly the central shaft, in which there is a corresponding number of teeth, that pass freely between the former.
The cylinder may also be placed upright, or horizontal if preferred, and mounted in any convenient framework. The central shaft should be put in rapid rotation, while the cylinder receives a slow motion in the opposite direction. The rice, as cleaned by that action, is discharged at the lower end of the cylinder, where it falls into a shute, and is conducted to the ground. The machine may be driven by hand, or by any other convenient motive power.[43] The growth of rice in North America is almost wholly confined to two States; nine-tenths of the whole product, indeed, being raised in the States of South Carolina and Georgia. A little is grown in North Carolina, Louisiana, and Mississippi.
The aggregate crop, for 1843, amounted to 89,879,185 lbs., while in 1847 it had risen to 103,000,000 lbs.
Besides the rice which is raised in the water, there is also the dry, or mountain rice, which is raised in some parts of Europe on the sides of the hills. It is said to thrive well in Cochin China, in dry light soils, not requiring more moisture than the usual rains or dews supply. By long culture the German rice, raised by the aid of water, is stated to have acquired a remarkable degree of hardness and adaptation to the climate. The upland rice of the United States is thought by some to be only a modified description of the swamp rice. It will grow on high and poor land, and produce more than Indian corn on the same land would do, even fifteen bushels, when the corn is but seven bushels. The swamp rice was originally cultivated on high land, and is not so now, because it is more productive in the swamp, in the proportion, as is said, of twenty to sixty bushels per acre; and the use of water likewise, it is stated, makes it easier of cultivation, by enabling the planter to kill the grasses. It is thought that on rich high land, rice may be made to produce twenty-five or thirty bushels to an acre in a good season. A letter from a gentleman in North Carolina gives the following account of some rice raised there. He says:—
"I have planted it the two past years with a view to private consumption only; not, however, with the success of my neighbours, who are famous, and have the things under their own management. They make from forty to fifty, and some, sixty bushels to the acre, on fine land that produces ordinarily from ten to fifteen bushels of Indian corn or maize. It is a larger grain than the gold or swamp rice, and very white; hence it is commonly called here the 'white rice.' It is planted generally about the middle of March, or 1st of April, in small ridges two-and-a-half feet apart, in chops at intervals of about eighteen inches, on the top of the ridge, ten or twelve seeds in each chop. A season that will make Indian corn, will, if long enough, make this rice; but it requires about four or five weeks more than the corn to mature. It ought to be cut before quite ripe, as it threshes off very easily, and is liable to great waste. Instead of the flail, we take the sheaf in the hand, and whip it across a bench in a close room until the rice leaves the straw. It does not stand the pestle as well as the swamp rice, but breaks a good deal in the beating; this, however, I have heard attributed to the dry culture."
A new variety of rice is mentioned as having been discovered in South Carolina, in 1838, called the big-grained rice. It has been proved to be unusually productive. One gentleman, in 1840, planted not quite half an acre with this seed, which yielded forty-nine and a half bushels of clean winnowed rice. In 1842, he planted 400 acres, and in 1843, he sowed his whole crop with this seed. His first parcel when milled, was eighty barrels, and netted half a dollar per cwt. over the primest rice sold on the same day. Another gentleman also planted two fields in 1839, which yielded seventy-three bushels per acre. The average crop before from the same fields of fifteen and ten acres, had only been thirty-three bushels per acre.
