This is the most highly esteemed of all grains, and has more enemies, and is more affected in its growth by the weather, than any other. It has engaged more attention in the study and writings of agriculturists than all other cereals. The outlines only of the results of the vast field of investigation and experiment on wheat-growing can be presented here. There are doubts respecting the origin of wheat. The more general and probable theory is, that it is the product of the cultivation, for a series of years, of a species of grass called Ægilops. This is indigenous on the shores of the Mediterranean, in those countries which, from time immemorial, have been the sources of our wheat. No one has ever found wild wheat in any country; it would be as strange as a wild cabbage or turnip. But the practical question is, How can wheat be most surely and profitably grown? The first requisite is a suitable soil. A clay or limestone soil is usually considered best, as there is much lime in wheat-bran. Such soil is better than light sand, or some of the poorer loams. But the large yields of wheat on the Western prairies, and on the rich alluvial soils of California river-bottoms, shows that the best of wheat may grow on other than clay lands. The truth of the matter respecting soils for wheat, is, that any soil good for corn, potatoes, or a garden, may, with proper tillage, produce the best of wheat. Experience in England, and in all the old countries on the continent of Europe, shows us that old land may be made to yield as large crops of wheat as the virgin soil of the New World. The production of wheat at suitable intervals, for a century, on the same land, need not lessen its power to produce good wheat in large quantities. Wheat is a plant demanding a rich soil, worked deep, and not too wet: these three things will produce a good crop on any land. We say to all farmers, raise wheat on any land that you can afford to prepare. First, if your land has not a dry subsoil, underdrain it thoroughly: water standing in the soil, and becoming cold or stagnant, is very injurious to wheat. Drainage is hardly more essential to any other crop than this. Next, plow deep. Subsoiling, on most lands, is very important to wheat. Manure highly, and put the manure between the soil and the subsoil: this attracts the roots deep into the soil, which is the greatest protection against winter-killing, and the effects of excessive drought. Render the surface of the soil as fine as possible. A finely-pulverized soil is as essential for wheat as for onions. Coarse lumpy soils are so open to the action of the atmosphere as to render the growth unequal, and cause the roots of the plant to grow too near the surface, for dry weather or the cold of winter. Always apply lime to wheat-lands, unless it be a limestone soil--not too much at once, but a few bushels to the acre annually. On no other crop do wood-ashes and dissolved potash, applied
