cow always shows a tendency to ‘‘milk thin” even under most nu- 
tritious feeding, while the poor milch cow shows a tendency to gain 
in live weight under similar feeding. It is probable that in most of 
our periods a full maintenance ration was being fed, and that the 
apparent loss of weight was due rather to this law, than to the char- 
acter of the food, and we may reasonably suppose from our data, 
that the loss was even less than would have occurred had a previ- 
ously ascertained maintenance ration been fed. It is difficult to in- 
terpret accurately the meaning of our figures upon live weight. If 
the average amount of water drunk daily be subtracted from the 
average live weight of the various periods, the difference in the 
weighings becomes less marked. 
The figures, as obtained, read, however, for the various periods :

It isthus seen that so far as these experiments go, the wastes of the 
starch and glucose manufacture, under whatsoever names sold, are a 
useful and advantageous cattle food. 
The influence of the foods upon the quality of the milk is not 
readily ascertained. We have a number of analyses of the morning 
milk, but the variation in quality from day today is marked. Such 
figures as we have can be formulated as below : 
Ceres. Juno.

IV, Vand VI 23 15.6 3.48 R2 12.9 3.74 
We have here the same fat percentage in Ceres’ milk under Hay 
feeding and Hay and ‘‘ wet feed,” and more fat under Hay and 
“‘dry feed ” than under Hay and meal feeding. In Juno, on the 
contrary, the largest per cent. of fat is under hay feed, the next un- 
der hay and ‘‘ wet feed,” the next under hay and dry feed, and the 
least under hay and meal feeding. An examination of the figures 
in detail, will convince, we think, that it will be difficult to trace a 
relation between the food and the percentage of fat in the milk, and 
the conclusion seems justifiable that the food during the various pe- 
riods was about equally potent towards maintaining the richness of 
the milk. | 
The conclusion justified by these trials must then be : 
1. Starch or glucose refuse, sold under the names of wet. feed, 
dry feed, starch meal, glucose meal and sugar meal was a valuable 
food for milch cows, when fed in connection with hay. 
2. Its value in practice varied with the amount of albuminoid 
contained in the ration, of which the starch food forms an important 
constituent.
