Field was °83 in. In the summer months there has been a discrepancy 
between the reading of the two gauges on several occasions. This is 
generally accounted for by the well-known fact that thundershowers 
are usually more or less of a local character. 
On December 12th, 1901, occurred the great snowfall of last 
Winter. Snow commenced to fall about 9 a.m., and continued, with 
little intermission, for 41 hours. The total amount recorded was 
1-43 in. At the Grange Field 1-57 in. was recorded in the same time. 
The diagram on this occasion is not entirely reliable, as it was noted 
that snow fell at first in a fairly dry condition, but as the day wore 
on it became wet, and as the instrument used will not register a fall 
of snow, unless it melts as it comes, the rate of fall cannot be ascer- 
tained. In this case, the rate was probably greater at the beginning 
f the fall than was registered, and less than the diagram shows later 
on, when the dry snow that would collect in the gauge would be 
gradually melted by the wet snow coming later. 
There are certain drawbacks to the instrument used, which may
