weeks the lambs were fed; cutting off all the pulp during 
the last thirty days. 
Lot III.—Alfalfa and sugar beets. 
Lot IV.—Alfalfa and sugar beets with grain consisting 
of equal parts of wheat and barley added during the last 
eight weeks the lambs were on feed, cutting off the supply 
of sugar beets during the last thirty days. 
The alfalfa was fed ad libitum , a complete record being 
kept of amount of fed and amount not eaten. It was the 
intention to feed all the pulp and beets that the lambs would 
eat, but it was not kept before them all the time. 
Each lamb was marked, and weighed separately once a 
week in order to keep complete individual records of them 
as well as accounts of the lots. The lambs were selected 
carefully in order that there should be no advantage of any 
one lot over another by having in it a superior class of in¬ 
dividuals. 
In Experiments I. and II., the feeding was done and the 
notes taken by senior students under the direction and 
supervision of one of us. Our acknowledgments are due 
more especially to Mr. E. P. Taylor and Mr. H. J. Faulkner. 
In computing comparative values and the cost of food 
eaten, cost for each pound of gain, etc., local market 
prices of the food used are as follows: 
Alfalfa on the farm, $4.00 per ton. 
Beet pulp delivered, $1.00 per ton. 
Sugar beets on the farm, $4.00 per ton. 
Wheat and barley. $1.00 per hundred pounds. 
RESULTS OF EXPERIMENT I. 
Nothing occurred to mar or interfere with this experi¬ 
ment except the necessity of feeding a small amount of 
grain during the first week to induce the lambs to begin 
eating the pulp and beets at once and a mistake which was 
made during the last three weeks when Lot III. receiving 
the beets were given grain. As all the lots received the 
same amount of grain the first week, the value of the com¬ 
parisons of one lot with another are not disturbed. By 
drawing the conclusions for the first five weeks and for the 
first ten weeks, we are able to eliminate the effect of the 
grain given during the last thirty days to the pulp and beet 
lots, and show the comparative value of beets and pulp. 
The beets showed a tendency to scour the lambs when 
they ate too large a quantity of them. The lambs in Lot 
IV. and one lamb, No. 7, in Lot II., were out of condition
