to a depth of four feet, to be 172 pounds. A similar trial with the 

 second year's growth gave 117 pounds. The details are set forth

Nitrogen in Clover Crop. 



In the same year Dr. Saunders, Director of the Dominion Ex- 

 perimental Farms, instituted a course of experiments to ascertain 

 if the growth of clover, using from two to ten pounds of seed 

 per acre, sown with grain, lessened the yield of the latter. The 

 results did not indicate any diminution in the weight of grain, nor 

 in any subsequent trial — and this experiment has been repeated 

 many times — have we found the yield to be materially affected 

 from the presence of the growing clover. 



In the following year an investigation to ascertain the rela- 

 tive merits of certain clovers as " cover " crops for orchards was 

 begun. The seed was sown in July, and the analyses were made 

 on plants collected in October of the same year, the roots being 

 t iken to a depth of two feet. The chemical data are given in the 

 subjoined table :
