250 REPORT OF THE CHEMIST OF THE 
In order to show more plainly to the eye the variation in the 
composition of the ash of several of our more common feeding stuffs, 
I have prepared two plates to accompany this article. Plate Ishows 
the per cent or pounds in one hundred of the ash of phos- 
phoric acid potash and lime, while the blank space shows the 
total per cent of other constituents, as soda, magnesia, iron, 
silicon, etc. 
Plate II shows the relative amount of phosphoric acid, potash, 
and nitrogen in one ton (2,000 lbs.), taking cottonseed meal as our 
standard ; that is, one ton of cottonseed meal was found to con- 
tain the most pounds (223.8 lbs.), of fertilizing matter of any feed 
examined, and in comparison with this the others stand as shown 
by the plate. 
INFLUENCE OF FERTILIZERS UPON THE CHEMICAL | 
COMPOSITION OF GRASS. 1887. 
In my report for 1887 I gave the restilt of an investigation upon 
the influence of several fertilizing ingredients on the chemical 
composition of timothy and clover. In the experiment there 
reported the fertilizers were spread upon the surface of a field 
which had already been in grass for five years. In the experi- 
ment now under consideration, carried out in the same year as 
above, thé fertilizers were applied to a plat well cultivated and 
then put down to grass. The grass selected for the purpose of 
this experiment was an annual Lolwm Italicum. A one-tenth 
acre plat was divided into 24 small plots and the fertilizers applied 
and the whole laid down to grass April 26. I may add that this 
plat had not been previously fertilized since the establishment of 
the Station. 
The following table gives the rate at which the different fertil- 
izing ingredients were applied :
