Remarks on the Foregoing Results. 



These tables of yields show, as would be expected, a few conflict- 

 ing results, but through the three years' tests the benefit of using 

 both potash and phosphoric acid may readily be seen, as also the 

 fact that, in most cases, when commercial nitrogen was used, the 

 returns in fruit failed to pay for the outlay. 



The beneiits derived from the use of potash or phosphoric acid 

 are not only the increase in yields, but these materials had a ten- 

 dency to harden the fruit, and to give them a richer color. In every 

 case where these have been nsed, the grower reports firmer and 

 better colored berries, which means better shippers and better sellers. 



It will be seen by a study of Exp. 1 that when an increase from 

 200 to 400 pounds of wood ashes was made, at a cost of not exceed- 

 ing one dollar, the yield was greater by 640 quarts than when only
