it as the American Standard Ration for dairy cows, is a hardly 
justifiable use of the word standard, and to set it up as a model 
for farmers in general would be very misleading. 
The Connecticut rations given in the table represent the 
actual practices of the dairymen whose herds were examined, 
so far as could be learned by weighing the foods fed day by 
day, and by determining their composition by chemical analysis. 
The factors used for calculating quantities of digestible nutri- 
ents are the chief sources of uncertainty here, but this is at 
present inevitable. In Germany there is a tendency to the 
more liberal use of protein, and the results obtained in expert- 
ments made in Massachusetts, as well as those here reported, 
indicate an increased milk and butter product and greater 
economy from rations containing quite large quantities of pro- 
tein as compared with rations low in protein. The tentatively 
suggested ration of the writers was based upon the German 
standard of Wolff, as regards the amount of protein. Asa 
result of some of our later experiments, and from close 
observation of the practices of many of our best feeders, we 
are inclined to believe that even larger quantities of protein 
than those here suggested would be better. We are now 
planning some further experiments for studying the question 
of the value of larger quantities of protein than that called for 
in our suggested ration. The ration proposed by the Wiscon- 
sin Station advocates less protein and more of fuel ingredients 
of the food than those contained in Wolff’s standard. ‘That 
the carbohydrates are more useful in the colder parts of this 
country than in milder climates is probably true, owing to 
their high fuel value. We must, however, remember that this 
class of foods will not prove a substitute for protein in milk 
production. ‘Their relative cheapness has tended to increase 
their use in this country, but because we feed them liberally 
does not imply, much less prove, that we are using them 
wisely. 
HERD TESTS DURING 1894-95. 
In the winter of 1893-94 tests were made with four herds on 
wide and narrow rations, and the financial as well as the 
physiological results were observed. During the winter of 
1894-95 four other herds were studied on the same plan. The
