pera'ture, summer and winter, as recorded by the Weather 

 Bureau for 20 years, is 46 degrees Fahrenheit. 



In summer the days get warm, even hot. Rarely does 

 the temperature reach 100 in the shade. In the shade one 

 almost always feels cool. It is always cool at night. The 

 perpetual snow in the mountains tempers the air, as does 

 the water on the sea coast. In the evening the cool air 

 from the snowy peaks rolls down the mountain sides and 

 out across the valleys. 



The climate of a region is dependent upon two im- 

 portant factors, warmth and moisture. On the Flathead 

 Reservation the fall rains come in late September or 

 October. During the winter the snow piles in the ravines 

 in the high mountains for summer use. The spring months 

 are delightful. Warm weather comes as early as March, 

 when spring flowers appear. At Missoula, buttercups are 

 usually gathered in February. Butterflies have been taken 

 as early as the middle of February. April and May are 

 delightful months, the latter usually of sunshine. June 

 brings refreshing rains, lasting until after the celebration 

 of our country's independence. July is likely to be with- 

 out much rainfall, and the first of September is likely to 

 bring showers. In July, August and September there are 

 weeks of sunshine and glorious weather. The rainfall of 

 the year averages 16 inches, varying from 15 to 20 inches. 



There are no cyclones. From the configuration of the 

 surface of the land, these are impossible. There are few 

 fierce wind storms, such as are experienced on the great 

 plains. 



Chinook winds occur in this section. These warm 

 winds lick up the snow from the valleys and lower hills, 

 and deposit the moisture on the higher summits. On 

 account of these winds snow does not lie long in the 

 valleys. There are usually several of these warm winds 

 every winter. At the time of this writing a strong chinook 

 is blowing at Missoula, and the few inches of snow disap- 

 pears fast. Often snow many inches deep may be evapor- 

 ated in a few hours. 



Mines. Claims, Etc. — There are no mining or other 

 claims, other than the allotments before mentioned, 

 on the range. There are no prospect holes. There need
