 small grains gave in this experiment as much as 70.2 

 and 62 bushels respectively.* 



The crop was thus more than doubled by the choice 

 of seeds and by planting them separately eight inches 

 apart It corresponded in Dessprez's experiments to 

 600 grains obtained on the average from each grain sown; 

 and one-tenth or one-eleventh part of an acre was suffi- 

 cient in such case to grow the eight and a half bushels

* The straw was eighty-three and seventy-seven cwts. per acre in the 

 first case ; fifty-nine and forty-nine cwts. in the second case (Garola, Les 

 Cereales). In his above-mentioned paper on "Thin Seeding," Major 

 Hallett mentions a crop at the rate of 108 bushels to the acre, obtained 

 by planting nine inches apart.
