The seed crop cures quickly. It may be drawn and threshed at once, or it may be stacked and threshed when convenient. If stacked, a goodly supply of old hay or straw should be put next the ground, and much care should be taken to protect the clover by finishing off the stack carefully with some kind of grass or hay that will shed the rain easily. Since the heads are very small and numerous, and since, as with all clovers, they break off easily when ripe, much promptness and care should be exercised in harvesting the seed crop. The best machine for threshing a seed so small is the clover huller. The yields of seed will run all the way from less than 3 bushels per acre to 5 bushels, and some crops have been harvested in Wisconsin which gave 7 bushels per acre. Four bushels would probably be about an average yield. As the price is usually relatively high compared with other clovers, the seed from white clover would be quite remunerative were it not that in a dry season the yield is disappointing. In some instances two crops are grown in succession; in others, one crop is reaped. The land is then sown to barley the next year, and the following year clover seed may be reaped again without sowing a second time. Usually, after two successive crops of seed have been cut, blue grass crowds the clover. It should be possible to grow prodigious crops of white clover in certain of the northern Rocky Mountain valleys, as, for instance, in Montana and Washington, where the conditions for the application of water to grow the plants and of withholding the same when ripening the seed are completely under the control of the husbandman. The soils in these valleys, as previously intimated, have high adaptation for growing white clover. =Renewing.=--White clover is probably more easily renewed than any plant of the clover family. In fact, it seldom requires renewal in a pasture in which it has obtained a footing as long as it remains a pasture. This arises from the abundance of the seed production and from the power of the same to retain germinating properties for a long period. Nevertheless, there may be instances when it may be wise to scatter more seed in the early spring in a pasture in which white clover may not be sufficiently abundant. It is also renewed, in a sense, when suitable fertilizer is applied on the pastures. A dressing of potash will greatly stimulate the growth of any kind of clover on nearly all soils; hence, the marked increase in the growth of the clover that usually follows the application of a dressing of wood ashes, especially in the unleached form. Top-dressings of farmyard manure are also quite helpful to such growth. The conclusion must not be reached that because white clover is not much in evidence in a permanent pasture for one or two, or even three dry seasons, if these should follow each other, that it will not come again and with great vigor and in much abundance when a wet season arrives again.
