REPORT 



OP THE 



CRUISE OF THE STEAMER CORWIN 



U. S. Eevenue Marine Steamer Corwin, 



San Francisco, November 7, 1884. 



Sir: I have the honor to submit the following report of the cruise of U. S. revenue steamer 

 Coricin, under my command, in the waters of Alaska, Behring Sea, and the Arctic Ocean, during 

 the months of May, June, July, August, September, and October, 1884, in compliance with orders 

 of the Department under date of April 18, 1884. 



Having completed arrangements and received on board the necessary supplies, at 1. p. m. of 

 May 3 we weighed anchor and stood out of San Francisco Harbor. At 8.40 p. ni. of the same day 

 departure was taken from Point Eeyes and the vessel's head was turned to the northward and 

 westward. 



For the minor details of the cruise to the Aleutian Islands, I would respectfully refer you to 

 the copy of the ship's log heretofore forwarded, nothing of special importance having occurred 

 requiring further notice. 



At 11.15 p. m. of May 15 we anchored in Ounalaska Harbor. On the following morning the 

 vessel was placed alongside the dock for the purpose of taking on board coal and water. Our 

 surplus stove-coal was put on shore that its room might be utilized. 



Rev. Mr. Hartmann and Mr. Wieland, the Moravian missionaries who had been granted 

 passage on the vessel by sanction of the Department, left the vessel at this place. 



In preparation for the severe work about to be performed fires were here hauled, boiler blown 

 down, and engine and boiler overhauled and cleaned. On the 19th fifty-four tons of the coal 

 belonging to the service and stored at this place was taken on board. 



At 10. a. m. of the 20th the town was visited by a very perceptible shock of earthquake, which 

 was felt on board ship. 



At 8 p. m. of the 20th, having filled fresh-water tanks and boarded the vessels in the harbor, 

 lines were cast off and we stood towards Bogoslov. 



At 6 a. m. of the 21st the vessel was anchored near this island, and Lieutenants Hall, Doty, 

 and Cantwell, together with Assistant Surgeon Yemans, were detailed to go on shore and gather 

 such information as they could concerning this remarkable volcano. Lieutenant Hall made a 

 flying survey of the island; Lieutenants Doty and Cantwell photographed several of the note- 

 worthy features, and Lieutenant Cantwell and Dr. Yemans made various notes, which were 

 embodied in the reports I had the honor to forward to the Department. 



I trust that the facts thus secured, together with the geological specimens obtained, will be 

 of importance to the scientitic men of the country, as I am assured they will be of interest to the 

 reading public. I regret that limited experience and time precluded the possibility of fuller details, 

 there being many phenomena which I think well worthy the time and investigation of our best 

 scientists.
