SOME GENERAL PRINCIPLES I7 



results usually follow sowing just after a light fall 

 of snow, which, as it melts, carries the seed down 

 into the little openings in the soil. But there are 

 areas, especially in the American and Canadian 

 northwest, where in some seasons the young clover 

 plants would be injured from sowing the seed quite 

 early. This, however, does not occur very fre- 

 quently. When sown on spring crops, as spring 

 wheat, barley r.nd oats, the seed cannot, of course, 

 be sown until these crops are sown. The earlier 

 that these crops are sown the more likely are the 

 clovers sown to make a stand, as they have more 

 time to become rooted before the dry weather of 

 summer begins. In a moist season the seed could be 

 safely sown any time from spring until mid-sum- 

 mer, but since the weather cannot be forecast, it is 

 considered more or less hazardous to sow clovers in 

 these northern areas at any other season than that 

 of early spring. If sown later, the seed will more 

 certainly make a stand without a nurse crop, since 

 it will get more moisture. If sown later than 

 August, the young plants are much more liable to 

 perish in the winter. 



In the States which lie between parallels 40° and 

 35° north, and between the Atlantic and the looth 

 meridian west, clover seeds may be sown in one form 

 pr another from early spring until the early autumn 

 without incurring much hazard from winter killing 

 m the young plants, but here also early spring sow- 

 ing will prove the most satisfactory. The hazard 

 from sowing in the summer comes chiefly from want 

 of sufficient moisture to germinate the seed.
