Before the millet blossoms, cut and cure it for hay. Keep all stock off the clover, plaster it the following spring, plow it under when in full bloom; sow buckwheat immediately; when up, sow plaster; when in full bloom, plow under and sow the ground immediately with rye, to be plowed under the next May. Thus three crops are put under within a year, the ground is left strong, light, porous, free from weeds, ready to grow a large crop of potatoes, or almost any thing else. Much is gained every way by having and keeping land in a high state of fertility. Some crops require so long a season for growth, that high condition of soil is absolutely necessary to carry them through to maturity in time to escape autumnal frosts. In the Western States manure has hitherto been considered of but little value. The soil of these States was originally very rich in humus. For a time wheat was produced at the rate of forty bushels per acre; but according to the statistics given by the Agricultural Department at Washington, for the year 1866, the average yield in some of these States was but four and a half bushels per acre. It is evident from this that Mr. Skinflint has had things pretty much his own way. His land now produces four and a half bushels per acre; what time shall elapse when it shall be four and one half acres per bushel? Who dare predict that manure will not at some day be of value west of the Alleghanies? New-Jersey, with a soil naturally inferior to that of Illinois, contains extensive tracts that yearly yield over one hundred bushels of Indian corn per acre, while the average of the State is over forty-three; and the average yield of the same cereal in Illinois is but little over thirty-one bushels per acre. In the Western States, where potatoes are grown extensively for Southern markets, the average yield is about eighty bushels per acre; while in old Pennsylvania could be shown the last year potatoes yielding at the rate of six hundred and forty bushels per acre. There are those who argue that manure is never necessary--that plant-food is supplied in abundance by the atmosphere; it was also once said a certain man had taught his horse to live without eating; but it so happened that just as he got the animal perfectly schooled, it died. Good, thorough cultivation and aeration of the soil undoubtedly do much toward the production of crops; but mere manipulation is not all that is needed.
