It is by skilfully feeding the wheat plant with all the nourishment that it can take up, that the crops may be indefinitely increased. Lord Hardwicke stated, in a speech before the Royal Ag. Soc. of England, that the fine Suffolk wheat had produced 76 bushels per acre; and another and more improved variety had yielded the astonishing quantity, of 82 bushels per acre. There is no comparison between the capacity of an animal and seeds, to produce results; for while the former is limited to a definite growth, which no effort of science or skill can augment, a seed may multiply beyond almost any assignable limit. We have been shown a stool of wheat, originating from a single seed, the growth of the present season, with 30 stalks, averaging from 100 to 110 grains on each head. Over 3,000 perfect grains, is thus the product of a single parent in one season. It requires, then, but the proper pabulum to produce good wheat, within the wheat latitudes, in every portion of the Union. Some of our worn-out eastern lands may be so totally unsuited to its growth, as not to justify the efforts of reclaiming or fitting them for this object, especially, while we have a region in the west, every way adapted by nature, to its most successful cultivation. But we can not for a moment doubt, that when those western fields become comparatively full, industry and science will combine to clothe again those hills and valleys (now but partially robed with a scanty herbage), with teeming crops of wheat, such as gave to them, in their pristine days, a fame for fertility seldom exceeded.
