difference of thirteen pounds being in favor of Lot II, but this is a 
difference of about .03 of a pound per day for each animal. The 
gain per day for the animals in Lot I averaged 1.66 pounds and 
for those of Lot IT 1.69 pounds per day for the entire period. 
We must then conclude that so far as this experiment goes to 
show the substitution of nitrogenous foods—like cotton-seed 
meal, etc., for corn meal and a small quantity of bran was not fol- 
lowed by any advantage as a fattening ration so far as the increase 
in live weight indicates. 
In general appearance Lot I looked much the best, having a 
- cleaner, brighter coat of hair, and this difference is shown in the 
case of the two steers by the photographs taken at the close of 
the experiment. 
The photographs of the meat shows little, if any, difference in 
the proportion of fat and lean. 
The butcher to whom the cattle were disposed of furnished us 
a sample of steak from each, also a roast. They were both cooked 
at the same time and under the same conditions. No one could 
mistake the difference. The meat from Whitey, carbonaceous fed 
animal, was much the tenderer and sweetest. Some allowance 
must, however, be made for Whitey was slaughtered first and the 
meat consequently was better “ripened.” In our estimation this 
difference would not account for so wide a variation as was found 
in the samples of meat, neither can we say the difference was due 
wholly to feed, since we can not determine the difference in 
individuality. 
DIGESTION EXPERIMENTS. 
During the winter of 1888-89 six digestion experiments were 
planned and carried out. These experiments are the united work — 
of Mr. Emery, Mr. Wheeler and myself. The digestion experi- 
ments were conducted with the animals used in the feeding trials — 
and the foods tested, the same as constituted the rations of the 
animals during several periods of the feeding. The object was _ 
to make the trials with such rations as are generally fed by farm- _
