29 was ushered in with a temperature of 20°, remaining con- 
tinuously below the freezing point until February 2, the end of 
this week recording a minimum of 10°. The week beginning 
February 5 again recorded a temperature way below freezing, 
middle of the day, with a minimum of 0° on the 
ascending above the freezing point on the 13th. This ae 
the long cold period of the winter. During this period of forty 
days, temperatures above the freezing point were recorded on 
about fifteen days, these higher temperatures occurring mainly 
during midday. No such protracted cold spell is recorded for 
the winter of 1910-11, the minimum for that winter being 7°, or 
13° higher than the minimum for the winter of 1911-12. 
A comparison of the precipitation for 1910 and 1911 shown in 
the above table of precipitation gives some interesting results. 
In 1910 a protracted drought during July, August and September, 
when only 3.16 inches of rain fell, was followed during October 
and November by a moderate precipitation, the two months 
totaling 5.21 inches. This moderate precipitation, after the 
extended drought, was readily and rapidly absorbed by the soil. 
In other words, woody plants were not made “ 
overabundance of water, the wood ripening up well. 
the precipitation during September was only 1.55 inches. 
dry spell was followed during October and November by a heavy 
rainfall, totaling 9.47 inches, almost twice the precipitation for 
the same period the previous year. This abundance of water 
would have a tendency to make wood soft, to retard its proper 
ripening, a condition not at all favorable for withstanding the 
unusually severe cold of the following January and February.
