 14-16, 33-34. March, 1919.— Nitrate of soda, superphosphate, and sulphate of potash were 

 tested as fertilizers for strawberries during the seasons 1916, 1917 and 191S. A fair average 

 increase in yields was obtained from plots on which nitrate of soda was applied either (1) 

 during blossoming time or (2) twice, early in the spring and at blossoming time. The value 

 of leguminous cover crops, especially clover, is also emphasized. A table of results is ap- 

 pended. — A. E. Murneek.
