gradual. Many a plant has been killed by sudden freezing when 
it might endure without detriment much lower temperatures 
arrived at gradually. Another factor is, of course, the subzero 
temperatures (for a period of two days) which are fairly unusual 
for December in this region. How unusual they are is shown by 
the fact that subzero temperatures have been recorded in Decem- 
ber only in four other years since and including 1871 (when 
records first began to be kept), namely in 1917, 13° below; 1880, 
6° below; 1876, 2° below; and 1871, 1° below. This of course 
applies to the month of December only. Subzero temperatures in 
January and February in past years have been somewhat more 
frequent. January has had eleven days with subzero tempera- 
tures since and including 1871 and February eleven. (March has 
never had a subzero temperature since records began to be kept.) 
ut it is probable that subzero temperatures in December are more 
harmful than those which come in January and February, for the
