Or under the hay and milk yield gained slightly towards 
the close of the period, and under hay lost slightly in 
weight. ; 
I fear the experiment was not. sufficiently well planned to 
enable us to deduce many certain conclusions. We may, 
however, say that corn meal seems to have but little specific 
effect upon the yield of milk, while cotton seed meal seems 
to have a marked effect upon the milk yield. Yet even 
here we may be deceived in this conclusion as the results 
may come from the increased amount of albuminoid con- 
sumed, as is indicated by the following summary of the last 
third of each period. See Table II. b.

RELATION BETWEEN TEMPERATURE AND CROPS. 
The relations between temperature and growth are quite 
close, and the mean temperature of the cycle in which crops. 
vegetate and ripen becomes instructive as indicating the 
useful plants which may succeed in a given locality. If we 
investigate the mean temperatures at the Station during 
the several years of occupancy, and examine into the yields. 
of each year, we may observe relations which are of interest 
to the farmer. For the purpose of attaining a correct idea. 
of the mean temperature, we take that of the soil; and as 
a further guide take the average of the extreme tempera- 
tures of each day, by which we form the following table. 
Mean soil temperature, 1 to 9 in. deep.
