400 lbs. acid phosphate. 



200-250 lbs. muriate of potash. 



350 lbs. Nitrate of Soda. 



No stable manure is supposed to have been used upon 

 the field under experiment for at least twenty years. 



Bulletin No. 46 of the Rhode Island Agricultural 

 Experiment Station, or Farmers' Bulletin No. 77 published 

 by the United States Department of Agriculture, tells how 

 and when to use lime. The details of the experiment here 

 referred to are to be found in Bulletins Nos. 82 and 90, 

 issued by the Rhode Island Agricultural Experiment 

 Station, Kingston, Rhode Island.

Clark's Grass Higganum, Conn., whose success in ob- 

 Cultivation taining remarkably large yields of hay for a 



number of years, an average of 9 tons of 

 cured hay per acre for i i years in succession, has been 

 heralded throughout the United States, attributes his suc- 

 cess largely to the liberal dressings of Nitrate of Soda which 

 he invariably applies to his fields early in the spring, and 

 which starts the grass off with such a vigorous growth as to 

 shade and crowd out all noxious weeds before they get 

 fairly started and which results in a large crop of clean and 

 high priced hav.

 about 70 degrees Fahr.) which is too late in the season to 

 benefit the early spring crops.
