The total rainfall between May 28th and June 12th, the 
respective dates of cutting and of putting into the mow, 
was 1.76 inches. The weather during this time was cloudy 
and the temperature ranged from 72 to 81 degrees. 
Any calculations based upon the above, without further 
data, would evidently be liable to lead to erroneous conclu¬ 
sions, but it suffices to show that the popular estimate of the 
value of such hay is not far from correct, i. e., about one- 
half that of good hay. The damage is not simply the 
amounts of proteids and nitrogen free extract (carbohy¬ 
drates) lost, but also the loss of those general qualities rec¬ 
ognized as essential to good hay. The mechanical loss in 
such cases is very large. We undertook Lo determine by 
direct experiment the total loss by the solvent action of 
water, fermentation, and handling, but it became evident 
that the results would indicate nothing of general value 
because there was no limit at which we would have to stop 
and no criterion by which we could judge when our experi¬ 
ment had become comparable with the average article (if 
there be such) of damaged hay. This sample gives us a 
somewhat definite measure of the sensitiveness of this hay 
to rain and exposure. The rain fell in three portions: the 
first fall amounted to .31 inch; the second r.49 inches; and 
the third .27 inch, with intervals of two days or more. The 
weather was cloudy and warm. The mechanical loss of 
leaves and stems would tend to change the composition of 
the hay in the direction indicated by the analyses, but for 
good reasons, we do not consider this to enter largely into 
this particular case; but attribute the changes in the compo¬ 
sition of the hay to the action of the moisture and heat.
