Fig. 40. — The acreage of timothy and clover mixed extends a little farther south and 

 Is somewhat more important in tlie West, especially in the North I'acitic Uetrion, tluxu 

 ttat of timothy alone. Clover is not as well adapted as timothy to heavy or sour soils, 

 fonsequently, timothy ajid clover mixed is more important on the better soils — in south- 

 eastern Pennsylvania, western Ohio, southern Michigan, northwestern Illinois, and Iowa. 

 In the.se sections timothy and clover commonly constitute the third year and some- 

 times the fourth year also, in a rotation, following corn and wheat or oats. About 

 two-thirds of the acreage of timothy and cltner mixed is in the Hay and Pasture 



Region. Compare with map of cotton acreage (Fig. 22) and of clover (Fig. 43).
