from a gauge with a 5 in. square receiver and 3ft. from the 
ground, now for four years, and heretofore I have found that 
the night fall almost regularly exceeded the day fall during 
the winter months. This year only two of those months 
show an excess of night fall over the day. During last sum- 
mer the excess of the day fall over that of the night affords 
additional evidence of the cause of the cold wet summer we 
experienced last year. The excess of the day fall over the 
night, and that too chiefly in the spring and summer 
months, was 4T36 inches. The greatest day falls occurred 
in April and July.

In the next table I present the average day and night 
fall for four years. This table shows as previous ones have 
done, that on an average the night fall exceeds that of the 
day in the coldest months of the year without exception. 
There is another noticeable feature in this average result 
that appeared in the three years’ average, namely, that the 
maximum of greatest night fall happens in February and 
again in December. Curious enough, too, in both the three 
and the four years’ averages June and August have an excess 
in the night rainfall.
