1906-7.] . CLIMATE OF YUKON TERRITORY. 295 
The following are the hours and minutes on the 21st day of each 
month that the sun is above an unobstructed horizon in the latitude of 
Dawson; January, 5", 55™; February, 9", 15™; March, 12%, 10"; April, 
E5n,-30.; May; 18", 51™; June.20%, 48"; July, 18", 54™* August, 15°, 307: 
September, 12", 10"; October, 95, 8"; November, 5%, 50"; December, 
45, 1™. As a matter of fact, however, Dawson together with many 
other of the centres of habitation is so much closed in by mountains 
and hills that the actual period of sunshine is less than indicated by 
the figures. 
. It is claimed that there is little wind at Dawson in winter and this 
jis to a large extent true. The cyclonic areas which enter the con- 
tinent from the Pacific pass far to the southward of latitude 64, hence 
barometric gradients are not usually steep.
