This increase can hardly have been accidental, because it was: er . 
noticed to take place in all the factories. The explanation lies in 
s the fact that the cows were turned into pasture about the middle Fi 
of May. The influence was not only an increase in yield of mille 
but also an increase of the milk-solids. Our season’s work, there- — 
fore, brings out incidentally the inftuence of food upon the com- a : 
position and yield of milk, (1st) when there was a change from i 
dry to succulent food, and (2d) when there was a change from — : 
succulent back to dry food: How much influence actual lack of es 
food had early in May and again when the pastures became dry, — 
it is impossible to say. It would appear, then, that an abrupt — 
change from dry to succulent food may produce the double effec 
of increasing not only the yield of milk but also an actual increas 
| of milk-solids in 100 pounds of milk; and a marked change from 
: succulent to dry food may produce, on the other hand, not ool Yo
