MEDIUM RED CLOVER 63 



ticularly damaging to the plants when they blow 

 fiercely just after a thaw which has removed a previ- 

 ous covering of snow. In some instances, one cold 

 wave under the conditions named has proved 

 fatal to promising crops of clover over extended 

 areas. 



In a general way, the southerly limit of vigorous 

 and reliable growth may be put at about 37°. But 

 in some localities good crops may be grown further 

 South, especially in some parts of Tennessee. Nor 

 would it be correct to say that medium red clover 

 grows at its best in many localities much south of 

 38°. On the plateaus it can be grown further South, 

 where the soil is suitable. 



This plant flourishes best in a moist climate. In 

 fact, the abundance and continuance of the growth 

 for the season are largely dependent on the amount 

 of the precipitation, and on the distribution of the 

 same throughout the season. In climates in which 

 it is usual for a long spell of dry weather to occur 

 in mid-summer, the plants will not make rapid 

 growth after the first cutting of the season; but 

 under conditions the opposite, they will grow con-« 

 tinuously from spring until fall. Continuous growth 

 may be secured through all the season on irrigated 

 land. Although the plants root deeply, they will suc- 

 cumb under drought beyond a certain degree, and 

 in some soils the end comes much more quickly than 

 on others ; on porous and sandy soils, it comes much 

 sooner than on clays. On the latter, drought must be 

 excessive to destroy clover plants that have been well 

 rooted. White clover can withstand much heat when
