CLIMATIC CONDITIONS.

The highness of the minimum temperatures given here for the winter months, 

 which are 30° to 40° above those of the Koyukuk country in the interior, is obviously 

 due to the moderating influence of the ocean. At Cape Bathurst, northeast of the 

 Mackenzie, in longitude 127° 30', and latitude nearly as far north as that of Point 

 Barrow, the lowest temperature experienced for the past two winters is reported by 

 Mr. Fox, one of the white keepers of a trading post here, to be —36°. 



Thunder is rare at Point Barrow, but is known by the natives to occur.

METEOROLOGIC RECORD FOR 1885-86, BY LIEUT. G. M. STONEY. 



The following temperatures and notes were taken by Stoney a on upper Kowak 

 River, principally at Fort Cosmos, about 120 miles from the coast, in approximate 

 latitude 66° 53', longitude 157° 23'. As they are continuous throughout a year, 

 they cover a more extended period of time than any other data yet made in the 

 interior of this northern country, and are regarded as one of our most important and 

 reliable records concerning it.
