in no sense to be regarded as accurately settled. Such calcula- 
tions of fuel values afford an approximate method for compar- 
ing different foods and feeding stuffs with respect to the quan- 
tities of energy which they are capable of yielding to the body. 
But these figures do not give an exact measure of the nutritive 
effects of the food materials. Indeed, we think they are in 
some cases quite far from such a measure. The total energy 
in the different feeding stuffs as obtained by burning with the 
bomb calorimeter was also determined in many instances. The 
whole subject of fuel values and nutritive effects of materials 
used as the food of animals and man is now being studied by 
the Station. 
lwo sets of averages are given in Tables 46 and 47 beyond. 
The first is the average of the samples published for the first 
time in the present report. The second is the average of:all 
analyses of similar materials made up to the present time in 
this laboratory. 
DESCRIPTION OF SAMPLES. 
The samples of feeding stuffs, the analyses of which are re- 
ported in the following tables, may be described as follows: 
GREEN FopDERS AND GRASSES. 
1,967, 1,968, 1,969, 1,970. Brome grass (Bromus inermts). — Grown 
in the Station grass garden in 1898. Samples were taken July 2d, when 
just past bloom. 
No, 1,967 was from a plot to which no fertilizer had been applied; 
growth, small, thin, pale in color, with little bottom growth. 
No. 1,968 was from a plot which had dissolved bone-black at the rate 
of 320 pounds per acre and muriate of potash at the rate of 160 pounds 
per acre. Growth, much like growth on plot without fertilizers. Thin, 
pale in color, but little bottom growth. — 
No. 1,969 was from a plot which had dissolved bone-black and muriate 
of potash at the same rate as 1,968, and, in addition, nitrate of soda at the 
rate of 160 pounds per acre. Growth, quite heavy, fair color, thick, and 
leafy. 
No. 1,970 was from a plot which had dissolved boneblack and muriate 
of potash at the same rate as 1,968, and, in addition, nitrate of soda at the 
rate of 480 pounds per acre. Growth, dense, heavy growth, dark green 
color, thick and leafy. 
1,856, 1,975, 1,855, 1,976, 1,857, 1.977, 1,858, 1,978. Meadow Sescue 
(festuca elatzor).—Grown in the Station grass garden in’ 1897-1898. 
Samples 1,855, 1,856, 1,857, 1,858, were taken on June 25, 1897, when a 
little past full bloom. Samples 1,975, 1,976, 1,977, 1,978, were taken 
July 2, 1898, when just past bloom. ga
