of course, those richest in protein or “ WAH formers,’’ while the 
more carbonaceous are those poorer in protein and having larger 
proportions of the fuel ingredients, t. e., fats, and especially the 
carbohydrates. The former, with smaller nutritive ratios (ratio 
or protein to fuel ingredients), tend to make narrow rations, while 
the latter make wide rations.

Ln 1892-93 stxteen herds were visited and a five-days test was 
made with each. In 1893-94 six herds were visited, and in four 
znstances the time of study of the feeding, management, and 
products of each herd was extended to twelve days. As soon as 
the analyses could be made the amounts of actual nutrients tn the 
rations fed were calculated, and in three cases other rations were 
suggested. The feed was gradually changed to the suggested 
ration with these three herds, and after four weeks from the close 
of the first test another twelve-days’ test was made with the new 
ration. . 
In 1894-95 four herds were studied on the same plan as in 
the longer studies made the previous winter, except that the 
length of time between the two tests, on the same herd, was 
shortened to two weeks. 
In general, there was the largest yield of milk and the largest 
butter production with narrow rations, t. e., those rich in protein. 
Wide rations—low in protein—did not, in these instances, favor 
large mulk or butter production. 
In the tests of 1893-94, and of 1894-95, when tt was possible 
to study the financial side of the feeding, narrow rations—rich in 
protein—were the more economical,
