that in 1907 the summer was initiated by severe rain showers 

 while the whole summer was exceptionally cool. 



Headquarters were established near Castella, only eight or 

 nine miles south of Upper Soda Springs in Siskiyou County, 

 where Henry Edwards and James Behrens collected Lepidop- 

 tera for many seasons. 



From Castella several expeditions of from 13 to 25 miles 

 into the mountains were made, and it was a pleasure indeed to 

 leave the valley when butterflies were becoming ragged and 

 warm to capture fresh and perfect specimens in the mountain 

 meadows, which, barring Culicidae, are a source of delight to 

 the entomologist. 



In the vicinity of Castella the steep wooded mountains draw 

 close together and the valley becomes canon-like, so that in early 

 summer insects alpine in habits are often found in the valley, 

 which is here about 1,900 feet above the sea level. 



On the east side of the Sacramento is a range of mountains 

 from 4000 to 6000 ft. high, beyond which is the McCloud 

 River, and on the west are the higher Trinity Mountains ris- 

 ing over 7000 ft. in several places, and terminating northward 

 in Mt. Eddy, 9,151 ft. high. This range is the dividing line of 

 Shasta and Trinity Counties, and is studded with small but 

 beautiful glacial lakes, always in a protected hollow on the 

 north slope of some rocky peak, and fed by its melting snows. 

 Such lakes visited were Echo Lake, the principal source of 

 Castle Creek, and situated at the base of the sharply conical 

 Tamarack peak 7000 ft. high; Gumboot, Bluff. Picayune and 

 Castle Lakes, the first three in Trinity and the last in Siskiyou 

 County; and finally, three unnamed lakes in the former coun- 

 ty, and giving rise to the east fork of the Trinity River flowing 

 westward to join the Klamath near the ocean. A trip was made 

 to Sisson to the north, and two to the swift blue McCloud 

 River, from different points. Needless to say, all these locali- 

 ties furnished a number of interesting Lepidoptera. 



C. Hart Merriam has made a careful study of the life zones 

 represented on Mt. Shasta (see N. A. Fauna No. 16, U. S.
