1. The amount of water in the timothy diminished rapidly after the 
period of full bloom. 
2. There was a large increase in the amount of crude fiber in late 
cut timothy, over that cut at period of full bloom. 
3. As the grass approached maturity there was a considerable 
diminution in the per cent of sugars, and an increase in starch. 
4. The proportion of albuminoids to the other organic constituents 
diminished after the period of full bloom. 
5. The albuminoids of timothy were much less digestible in the late 
cut hay than in that at full bloom. 
6. Between the period of full bloom and seed formation there seems 
to have been a reduction of some of the albuminoids to the amide 
form, probably in the course of the albuminoids being transferred from, 
the stem to the seed, or in some way connected with the formation ox* 
translocation of the sugars and starch. 
7. From our experiments it seems that the increase in the quantity 
of timothy, after the period of full bloom, was not sufficient to over- 
balance the lower digestibility of the albuminoids, together with the 
large increase in fiber. 
8. Finally, from a chemical point of view, it seems preferable to cut 
timothy, for feeding, at the period of full bloom, rather than after the 
seeds have formed. 
HAYS FROM DIFFERENT LOCALITIES. 
For the purpose of determining the average chemical composition 
of hay, or of any agricultural product, it is necessary that samples be 
secured from different localities, in order that we may determine the 
climatic and other influences which affect the composition and 
productiveness of the crop. Such samples should be had for a number 
of years, that we may know what yearly changes are to be expected 
for each locality. It is shown from the analyses under the head of 
" Variation in the chemical composition of grasses for two years," that 
we may expect as great difference between the same kind of grass 
grown on the same plat for two successive years as between that from 
widely separated localities, so that the hay from any locality must be 
examined for a series of years before we can determine the average 
composition for that locality, and from these averages must be 
gathered the average for the product. 
As a beginning to the study upon the composition of the grasses., a 
few samples of timothy have been secured, during the past year from 
Wisconsin and from Maine, for which I am indebted to Dr. H. P. 
Armsby, of the Agricultural Experiment Station at the University of
