and Observations" made during that cruise and issued by tlie Treasury Department. The geo- 

 graphical results of the expedition between the Yukon delta and the Kuskoquim have appeared, 

 with a map, in the "Proceedings of the Eoyal Geographical Society and Monthly Eecord of Geog- 

 raphy " for November, 1882, and are embodied with other information in the " Eeport on the Pop- 

 ulation, Industries, and Resources of Alaska," prepared by Ivan Petrofif for the Census Office. 



A report upon the meteorology of Saint Michaels, and vicinity, made to the Chief Signal 

 Officer, and a series of illustrations and notes contained in the official report of the Corwin's 

 cruise by Captain Hooper, have also been published. 



The volume devoted to Alaskan ethnology, upon -which the author is engaged at present, will 

 complete the series. 



In closing this brief outline of work accomplished I take pleasiire in acknowledging my 

 indebtedness for favors received from the Alaska Commercial Company and particularly from its 

 officers at Saint Michaels, Messrs. Neumann and M. Lorenz. To their genial companionship 

 I owe many pleasant hours during the wearying monotony of life in this isolated region; and 

 without their kindly assistance it would have been impossible for my work to have been carried 

 on so successfully. The fur traders, one and all, forwarded my work with voluntary assistance, 

 and my thanks are particularly due to Messrs. L. N. McQuesten, Charles Petersen, Fredricks, 

 and Williams. 



My thanks are also due Prof. S. F. Baird for placing the material in the Smithsonian Institu- 

 tion and National Museum at my disposal and for aid extended in various other ways. 



To Messrs. W. H. Dall, Eobert Eidgway, and Dr. L. Stejneger I must also express my obligations 

 for favors conferred since my return from the north. The latter gentleman has conferred valued 

 assistance in the revision of the bird report. • 



Finally, I wish particularly to acknowledge the kind services of my friend, Mr. H. W. Henshaw, 

 in connection with this report. He has revised the nomenclature of the ornithological portion in 

 order to bring it into accord with the Check List of the American Ornithologists' Union, now the 

 standard in this country, and has had editorial supervision of the entire volume.
