Ash Analyses. 
Partial ash analyses were made for a few of the grasses, for both 
years, and the results are given in the following table :

In order to compare these analyses to learn the real differences, it is 
necessary to calculate the ash analysis on the dry substance, and the

An inspection of the table of analyses for the dry substance shows 
the hays for this season to be considerably richer in albuminoids than 
were the hays from the same plats last year, while the nitrogen free 
extract is proportionally lower. The next point of importance is to 
know how the yield per acre compares for the two years. Unfortu- 
nately, no account was taken of this, but my colleague, Mr. Plumb, has 
furnished me with some figures for the yield of hay upon the Station 
plats which will serve as an indication of how the yield compares for 
the two years. The grass on 100 square feet of the same plats from 
which my samples were taken was cut and the hay weighed for each 
year, and was as follows:
