season. The party consisted of Allen E. Hasselborg of Juneau, 

 Alaska, and the writer. Our means of transportation was a 

 gasolene launch, twenty-eight feet long and seven foot beam. 

 Camp was established ashore at most of the points visited. 

 Hasselborg spent most of his time in hunting the larger mammals, 

 though he occasionally ran lines of small traps, or shot a few 

 birds, leaving the writer free to devote himself entirely to the 

 small mammals and birds. 



The region explored by this expedition, together with that 

 of 1907, includes practically the whole of the Sitkan district 

 as restricted by later writers : the mainland coast of Alaska and 

 the islands (the Alexander Archipelago) lying between Juneau 

 and Cross Sound on the north, and Dixon Entrance on the south. 

 This area is about two hundred and fifty miles long, from 

 Cross Sound to Dixon Entrance, with an average width of 

 about one hundred miles. The previous expedition had collected 

 at various points on the more northern islands of the group, 

 Admiralty, Chichagof, and Baranof, as well as at Glacier Bay 

 on the mainland; so it was planned to begin operations south 

 of Frederick Sound, work south along the western edge of 

 the archipelago as far as Dixon Entrance, and, on the return 

 trip north, to visit the inner islands, and such mainland points 

 as time permitted and it seemed desirable to explore. 



I left San Francisco on March 31, arriving in Juneau on 

 April 8. We left Juneau on the morning of April 9, and on 

 October 1, I sailed for home from the same point. During 

 October and November Hasselborg visited the Taku River and 

 points on Admiralty and Chichagof islands, collecting material 

 which has been included in the present report. The following 

 is the itinerary of the expedition :
