EFFECT OF AMMONIA UPON WHEAT. 77 



These facts seem to show that as the ammonia in the man- 

 ures increase, the yield of the crop grown is larger, and the 

 more nitrogen is contained in the produce. Similar results 

 have occurred in the ordinary operations of the farm and 

 the facts have led farmers to use artificial manures rich in 

 ammonia for the express purpose of procuring more valua- 

 ble grain and a larger yield of it. Millers knowing these 

 facts have taken special pains to acquaint farmers with 

 them, with the purpose to procure a better quality of grain 

 for making more valuable flour.
