most naturall}' belong- ? Only a small part of the wheat, oats, 

 and barley should be grown below Mason and Dixon's line, 

 because the yield is not sufficiently large to justifj' it in com- 

 parison with values produced by crops of cotton, corn, rice, 

 cowpeas, and garden and orchard crops. 



Above that line and well toward the Canadian border winter 

 wheat yields moderate value to the acre. It here holds a splen- 

 did place In the rotation, because it follow^s corn so well, re- 

 quires labor at a time of year when other crops are not suffering, 

 and serves as a nurse crop for clover and grass seeds planted to 

 make a crop the following year. 



Along the northern border and over in Canada spring wheat 

 takes the place of the winter wheat, though its average value 

 to the acre is even lower. 



The modern binder 



Oats do not thrive well so far south as does winter wheat, 

 not having been as yet bred for hot summer weather, but are 

 grown nearly to the Gulf. The barley zone is still further north 

 than the oats. 



Rye sown in the autumn is hardy to the northern counties of 

 the United States and thrives south to Mason and Dixon's line. 

 The millets and non-saccharine sorghums are grown well to the 

 north and kafflr corn has an especial usefulness on the droughty 

 plains where it produces grain with light rainfall. 



Great Advance ixi Rice Growing in America — Rice on the 

 other hand has a distinctly southern habitat and is local. The 

 rice area recently has mainly moved from the Atlantic coast 

 states to Louisiana and Texas and its area has greatly extended. 

 Its method of cultivation too has radically changed, and it has 

 now come under America's broad plan of farming with machines.
