THE CALL OF THE LAND 



be overcome by these means to a very great

 Kherson oats and macaroni wheat and by 

 the wonderful achievements attained in the 

 breeding of seeds for all sorts of purposes; 

 within very large limits you can create in 

 seeds and so in crops whatever powers and 

 properties you please. In corn you can, by 

 a few years' breeding, increase the oil, the 

 starch, or the protein six, eight or 10 per 

 cent, and probably more. The ability of a 

 crop to withstand drouth, to get on with 

 minimum water, can be increased in the 

 same way.

 son, Eli Whitney and Edison, that of so 

 storing up water in the soil to be cultivated

 and spring have left, and to put the surface
