CLIMATIC CONDITIONS.

"When the thermometer is minus, it is denoted ( — ). 



"The temperatures during the months of July and August were taken partly at 

 Fort Cosmos and while at work on the river. The others were taken at Fort Cosmos 

 and an accurate temperature taken every hour by spirit thermometers remaining out- 

 side. These were the best (registered) spirit thermometers, made specially for 

 the Government for arctic observation. 



"A person can't be too much impressed with the importance of watching the ther- 

 mometer. I would recommend that the spirit thermometer have the liquid colored, 

 as the white liquid is hard to read. The thermometer should also be protected by 

 a wooden case, leaving only the bulb exposed, and even that should be screened. My 

 observations were the mean of three excellent spirit thermometers." 



TEMPERATURES IN 1901. 



Following are lists of temperatures encountered by the party. The record 

 was kept by Gaston Philip. As the primary objects of the expedition could be 

 obtained only by making daity moves, which were necessarily made at irregular 

 hours during the twenty -four, these notes are not so complete as might be desired, 

 but they will serve to give a fair idea of the general conditions that prevailed.
