The easterly winds predominate in the country to the northward of Great Slave Lake, as
appears on a reference to the Table; and whilst they continue to blow, the weather is milder than
during the westerly winds. In December and January, the coldest months, the latter prevailed.
The coldest, and I may add, the strongest wind in every season in this country, is the NW.
The easterly, southerly, and westerly winds were almost invariably accompanied by clouds and
snow, especially the two former. The thermometer was generally lowest on clear nights, when
the shy was of a deep blue ; and the blue sky invariably appeared at Fort Enterprise, when the
temperature was below - 40°. A strong wind always raised the thermometer, though it blew
from the coldest quarter, and clouds* though unaccompanied by winds, had the same effect.
During our residence in the country, we had many opportunities of confirming the remarks in
Captain Parry’s Voyage, (page 143,) respecting the distance which sound is conveyed in intense
cold weather.
