Experiment of F. A. Herrick; Easton. 



Crop, potatoes, planted June 1 by band, 5 rows to a plot and 

 50 hills in a row. No misfortune happened to the crop except 

 missing hills. As the missing hills varied with the different plots, 

 in the table the yields are calculated for 250 hills per plot.

8 and Srt 









In this experiment nitrate of soda and muriate of potash 

 mixed and separately seems to have worked absolute harm to the 

 crop, though when combined with dissolved bone black they pro- 

 duced an increase in the crop. So far as cost of increase per 

 bushel is concerned, the results are slightly in favor of dissolved 

 bone black and muriate of potash.
