Northwest during the five colder months of the 

 year. Though of brief duration, these winds 

 are very efficacious in softening the asperities of 

 winter with their moderating warmth, and they 

 are of great assistance to the stock and other 

 interests. Apparently the Chinook starts from 

 the Pacific, in the extreme Northwest, warm 

 and heavily moisture-laden. Sweeping east- 

 ward, it is chilled in crossing the mountains, 

 on which it speedily releases its moisture in 

 heavy snowfalls. Warmed through releasing 

 moisture, it is still further warmed through com- 

 pression while descending the Cascades, and 

 it goes forward extremely feverish and thirsty. 

 It now feels like a hot desert wind, and, like air 

 off the desert's dusty face, it is insatiably dry 

 and absorbs moisture with astounding rapidity. 

 It may come from the west, the southwest, 

 or the northwest. Its eastward sweep sometimes 

 carries it into Wisconsin, Iowa, and Kansas, 

 but it most frequently floods and favors the 

 Canadian plains, Oregon, Washington, Mon- 

 tana, Idaho, Wyoming, and Colorado. It may 

 come gently and remain as a moderate breeze
