Fig. 43. — Thi.s map shows the acreage of clover grown alone (for timothy and clover 

 mixed see Fig. 40). "Clover" may mean red, mammoth, or alsike clover in the Northern 

 and Central States, crimson clover, a very different plant, in the coastal plain of Dela- 

 ware, Maryland, and Virginia, bur clover in parts of the South, and was specifically 

 stated in the census schedule to include lespedeza. Consequently, the map above, like 

 that of wild hay, includes several different plants, all legumes, however. Most of the 

 clover acreage, it will be noted, is located in the Corn Belt and the Corn and Winter 

 Wheat Region, particularly along the lower Ohio River and up the Mississippi as far as 

 St. Louis. Much of this clover is grown for seed as well as for hay. 



« ^^S- ■**• — ^^'^ ™^P shows the geographic distribution of the census item entitled 

 Other tame or cultivated grasses cut for hay." In New England and New York it 

 consLSts mostly of redtop, quack grass, orchard grass, and Canada blue grass ; the dense 

 center in southern Illinois is largely redtop ; in the Black Prairie of Alabama and 

 Mississippi, and in general throughout the South, the dots represent Bermuda and JohnJ 

 son grass principally ; while in eastern Tennessee orchard grass and tall rye grass 

 probably constitute most of the acreage shown. The scattered acreage in the State 

 from North Dakota to Texas is almost wholly millet, Sudan grass, or amber cane.
