Missouri farmer can expect to average for _his_ Corn. The abundant fodder would also be worth in New-Jersey at least double its value in Iowa; and I judge that the farmer able to buy, prepare, fertilize, and cultivate 1,200 acres of the Jersey "barrens," could make more than thrice the profit to be realized by the owner of 400 acres. He would plow and seed as well as thrash, shell, cut stalks and straw, and prepare the food of his animals, wholly by steam-power, and would soon learn to cultivate a square mile at no greater expense than is now involved in the as perfect tillage of 200 acres. This essay is not intended to prove that Grain is not or may not be profitably cultivated at the West, nor that it is unadvisable for Eastern farmers to migrate thither in order so to cultivate it. What I maintain is, that Wheat, Indian Corn, and nearly all our great food staples, may also be profitably produced on the seaboard, and that thousands of square miles, now nearly or quite unproductive, may be wisely and profitably devoted to such production. Let us regard, therefore, without alarm, the prospect of such a development and diversification of Western Industry as will render necessary a large and permanent extension (or rather revival) of Eastern grain-growing. XXIX. ESCULENT ROOTS--POTATOES. In no other form can so large an amount and value of human food be obtained from an acre of ground as in that of edible roots or tubers; and of these the Potato is by far the most acceptable, and in most general use. Our ancestors, it is settled, were destitute and ignorant of the Potato prior to the discovery of America, though Europe would now find it difficult to subsist her teeming millions without it. In travelling pretty widely over that continent, I cannot remember that I found, any considerable district in which the Potato was not cultivated, though Ireland, western England, and northern Switzerland, with a small portion of northern Italy, are impressed on my mind as the most addicted to the growth of this esculent. Other roots are eaten occasionally, by way of variety, or as giving a relish to ordinary food; but the Potato alone forms part of the every day diet alike of prince and peasant. It is an almost indispensable ingredient of the feasts of Dives, while it is the cheapest and commonest resort for satiating or moderating the hunger of Lazarus. I recollect hearing my parents, fifty years ago, relate how, in their childhood and youth, the poor of New-England, when the grain-crop of that region was cut short, as it often was, were obliged to subsist through the following Winter mainly on Potatoes and Milk; and I then accorded to those unfortunates of the preceding generation a sympathy which I should now considerably abate, provided the Potatoes were of good quality. Roasted Potatoes, seasoned with salt and butter and washed down with bounteous draughts of fresh buttermilk, used in those days to be the regular supper served up in farmers' homes
