a. If, in the first of the foregoing tables, we compare the 
variations in the amount of milk-solids, we notice that, month 
for month, the variations are quite uniform. In the general 
averages for the season, the results are remarkably close, when 
we consider the variety of conditions Eos which the milk was 
produced. 
b. In studying the monthly averages for 1893, we notice that 
there was a constant increase in solids through April, May and 
_ June, then a marked decrease in July, which continued through 
the first half of August, after which the solids increased and 
continued so to do during the rest of the season. 
The question at once suggests itself as to why the months of 
July and August formed an exception to the general rule that 
the milk-solids increase as the period of lactation advances. As 
we shall see later, the change was such-as to have a far-reaching 
influence upon the composition of the milk and upon its relation 
to cheese-making. Only one explanation can be found for the 
facts: In July the pastures commenced drying up and this con- 
tinued well into August; this condition was made worse by the 
_ activity and number of grasshoppers that came in August; add © 
_ to this the effect of the warm weather and annoyance by flies and 
__ we haye what is undoubtedly the true explanation of the facts 
- observed. It has been very generally believed that decrease of 
yield of milk is always accompanied by increase of. milk-solids. 
_ We appear to have an exceptional case here, and it will be of 
_ especial interest to notice upon what constituents of the milk- 
solids the decrease largely fell. There was, of course a really 
? Spetnormal condition in the matter of food, to say nothing of other
