FIELD EXPERIMENTS WITH FERTILIZERS. 133 
There was a gradual increase in yield with the increased quan- 
tities of nitrogen used. The crop in general did not show a very 
marked increase from the use of fertilizers. This was doubtless 
due in part to the severe drought during July and the greater part 
of August. The experiment confirms those made on the field 
with meadow grasses, in demonstrating the importance of nitro- 
genous fertilizers in the growth of grasses.

COMPOSITION OF THE CROP. 
Samples of from 15 to 19 pounds were taken from each plot just 
before the hay was carted. These were cut into one-half inch 
lengths and sub-samples (of 3 to 5 lbs.) were taken for analysis.
