including the vicinity of Lake Waha and Craig's Mountain, south of 

 Lewiston ; Mount Moscow, near the town of Moscow, the type locahty 

 of many species described within the past 20 years ; Gold Hill, and 

 Yale, northeast and east of Potlatch. 



In order to visit so many scattered places, the trip was made by 

 automobile. My wife accompanied me, and we camped most of the 

 way. Our route was to Colorado Springs, across the Rockies by 

 Tennessee Pass, through Salt Lake City to Wells ; thence to Reno, 

 crossing the Sierras at Tioga Pass, just above our camp at Ellery 

 Lake ; thence across the San Joaquin Valley to Monterey and north 

 to San Francisco ; up the Sacramento Valley and through Western 

 Oregon to Portland, and through the Inland Empire to Spokane ; 

 thence by Missoula, Butte and Three l^orks to the Yellowstone Park ; 

 crossing the Big Horn Mountains in Wyoming, and home across 

 South Dakota, Southern Minnesota, etc. The distance traveled was 

 over 9,000 miles, and the trip was made without mishap. The accom- 

 panying illustrations show a few of the collecting places and some- 

 thing of the traveling and camping conditions. 



Several thousand flies were brought back ; it will recjuire more time 

 to study the material sufficiently to tell how many species new to 

 science were obtained, but there is no reason to doubt that the results 

 were of substantial value.
