REPORT OF THE DIRECTOR. ; He 
attention being given to the feeding value of forage crops. At 
the same time more or less extended observations have been 
made of the actual feeding practice of intelligent dairymen in 
different parts of the State. In carrying out these obser- 
vations a representative of the Station has spent several days 
at each place, and has made weighings of the feed and of 
the inilk determining the amount of butter-fat in the milk of 
each cow and taking samples of each feeding stuff for analysis 
by the Station. Ina number of cases when such observations 
have been carried on for a certain period, the Station has made 
suggestions as to advisable changes in the feeding, and after 
the changes have been made the effect upon the milk produc- 
tion has been observed by a second period of observations sim1- 
lar to the first. During the past five years some 45 tests have 
been made with 453 cows in 32 herds in different parts of the 
State. The college herd at Storrs is now available for experi- 
mental purposes, and series of experiments are in progress 
there as in other places in the State. The main object of 
these experiments has been to find how farmers in the State 
are feeding, and, by comparing their methods with the teach- 
ings of experiments elsewhere, to make suggestions for improve- 
ment. At the same time the management of the experiments 
has been such as to bring new and valuable information regard- 
ing the economy of the feeding of cows for the production of 
milk and butter. The experiments of the past year, like those 
of previous years, point quite clearly to the value of rations 
with large proportions of protein for milk production. 
A summary of the work done in this line by the Station up 
to the present time, together with reference to the results of 
similar inquiries elsewhere, forms the subject of the first two 
articles of the present Report. 
EXPERIMENTS WITH THE RESPIRATION CALORIMETER, 
Experiments of the kind above reported do not bring the 
exact information that the farmer needs for the most economi- 
cal feeding of his stock, for the reason that they do not reveal 
the underlying laws of animal nutrition. To discover these 
experimenting of a more detailed and abstract nature is re- 
quired. During the past thirty years or more the advance of 
knowledge regarding the nutritive values of feeding stuffs and
