RESULTS OF ANALYSES OF FODDERS AND FEEDING 
STUFES. 7 
BY CHAS d.. WOO DS. 

In connection with the work of the Station, analyses of the 
following miscellaneous feeding stuffs have been made by the 
Station chemists. For the most part the analyses were made in 
connection with feeding experiments or experiments upon the 
growth of plants. In no case were they undertaken merely to 
increase the amount of this class of data. The methods of 
analyses recommended by the Association of Official Chemists 
were employed. 
The results of the analyses as calculated to water content at 
harvest or at the time of analyses are given in table 1, page 21, 
_which follows the description of samples. In this table the ma- 
terials are grouped somewhat according to their water content at 
time of taking samples as follows: Green fodders; silage; field- 
cured hay; cured hay and fodder; grain; and milling products. 
This order is also observed in the descriptions of samples. 
The results calculated to water-free (dry matter) as the basis 
are given in table 2, page 24. 
The potential energy, or fuel value, of a pound of each of the 
feeding stuffs as given in the tables, was obtained by multiplying 
the number of hundredths of a pound of protein and of carbohy- 
drates by 18.6, and the number of hundredths of a pound of fat 
by 42.2, and taking the sum of these three products as the num- 
ber of calories of potential energy in the materials.* 
DESCRIPTION OF SAMPLES. 
In the description of samples the same order of arrangement is 
observed as in table r. 
GREEN FODDERS. 
1218-1221, Oat Grass (Avena elatior),—Grown in grass garden in 1893. 
The sample was taken June 24th, at which time the seeds were beginning to 
form. There was a fair yield of quite pure oat grass. No. 1218 was from a 
plot without fertilizers. No. 1219 was from a plot supplied with dissolved bone- 
black at the rate of 320 pounds per acre, and with muriate of potash at the rate
