AGRICULTURAL EXPERIMENT STATION. 15 
Moxness, a post-graduate student, has been appointed labora- 
tory assistant at the Michigan Experiment Station. 
Chemical analyses have been made for nearly all of the 
other divisions of the Experiment Station, as milk, fodders, 
forage and root crops, paris green, etc. In cases where the 
chemical analyses have formed a prominent feature of the 
work, and the conclusions have been based largely upon chem- 
ical data, the work has been done on a cooperative basis, each 
division doing its share of the work and receiving due credit 
for the work performed, and bearing its portion of the ex- 
pense. A large amount of free analytical work has been done 
for the farmers of the state; numerous samples of miscellane- 
ous materials having been received from time to time. ‘This 
feature of the work of the Division of Agricultural Chemistry 
has, it is believed, given quite satisfactory results, and has 
been maintained at comparatively little expense. 
DAIRY DIVISION. 
In this division systematic records have been kept from the 
time it was organized of all food stuffs consumed by each 
animal, the composition of same, the daily yield of milk, butter 
fat and other solids in the milk, the daily consumption of feed 
by young stock from time of birth, and weekly gain in growth. 
In earlier years these data were used in determining the kind 
of cows that make best return in the dairy, the cost of milk 
and butter production, the cost of rearing the young and best 
methods of feeding for the production of stock intended for the 
‘dairy. During later years the data have been used in a study 
of the fundamental principles bearing upon animal nutrition. 
Since the publication of bulletin 71, referred to in the last 
report, a supplementary report has been made in bulletin 79, 
treating on the “Food of Maintenance, Nutrient Requirements 
in Milk Production, Protein Requirements and the Influence 
of the Stage of Lactation on Nutrient Requirements.” These 
subjects are presented by Professor Haecker, under new and 
improved methods, showing that the standards for food of 
maintenance and for milk production, in general use, are not 
reliable guides in feeding practice. In this bulletin new stand-
