than the hay, and all of the conditions under which the experiment 
was conducted were favorable. In this second experiment we also 
used three sheep, young ones, and made them just as comfortable 
as possible, and again the results indicate that this hay fed alone 
will simply maintain the weight of the lot. In this case sheep No. i 
gained ^ of a, pound; sheep No. 2 gained ^ of a pound, and sheep 
No. 3 lost of a pound. The total weight at the beginning of 
the feeding period was 243.25 pounds, at the end of the period 244.0 
pounds, a gain of three-quarters of a pound. It was rather sur¬ 
prising that sheep No. i should show any gain, for the animal 
evidently did not like the hay and ate much less of it than the 
others, about two-fifths only of the average of the other two sheep. 
I will not go into the details of this case, but do not think that it, 
should be included in averaging the results. The only good pur¬ 
pose that it serves is to show how very different the results with 
some individual animals may be from the average, and further to 
emphasize the fact that some individual animals do not take kindly 
to this fodder. Though the general tenor of the statements regard¬ 
ing this point would lead me to infer that sheep take to it better 
than other animals. The composition of this hay, made from quick¬ 
ly grown plants, the feeding data, composition of the feces and the 
coefficients of digestion are given below:
