of the Interior, Canada, for the taking of migratory birds ; the United 

 States Department of Agriculture, for game mammals in Alaska ; the 

 United States Department of Commerce, for fur-bearing mammals in 

 Alaska; Mr. F. Kermode, Director of the Provincial Museum, Vic- 

 toria British Columbia, for game and non-game birds and mammals in 

 British Columbia. 



I am under obligations to the Bureau of Biological Survey of the 

 United States Department of Agriculture, through its chief, Dr. E. W. 

 Nelson, for the loan of specimens, for the identification of certain 

 species, and for the determination of the contents of bird stomachs. 

 In this connection particular mention should be made of the identifica- 

 tion of the shrews of the genera Sorex and Microsorex by Dr. Hartley 

 H. T. Jackson, who examined all my material except four specimens 

 in alcohol; and of the examination of a considerable number of birds' 

 stomachs by Mr. Charles C. Sperry. 



From the Victoria Memorial Museum, Ottawa, through Mr. P. A. 

 Taverner, and from the Provincial Museum, Victoria, British Columbia, 

 through the director, Mr. F. Kermode, I received the loan of specimens 

 of various species of birds. , 



The plant names used in this report were supplied by Dr. F. J. 

 Smiley, of the University of California Herbarium, based upon speci- 

 mens collected on this expedition that have been deposited in the 

 Herbarium. 



Advice and information was received from Mr. Ernest P. Walker, 

 an employee of the United States Bureau, of Fisheries who was sta- 

 tioned at Wrangell, Alaska, at the time we were pursuing our field 

 work in that region. Mr. "Walteer supplied data on certain species 

 from the vicinity of Wrangell, and he has presented to the Museum 

 of Vertebrate Zoology specimens of birds and mammals from the same 

 region that are desirable additions to the Museum collection. 



I take pleasure in expressing my gratitude to Mr. W. H. Dodd, 

 government agent at Telegraph Creek, for assistance and advice during 

 our stay in the region over which he has jurisdiction.
