FISCAL YEAR ENDING JUNE 30, 1S7». 



During this year important surveying work was done on 

 the west coast of Mexico, from Mangrove Point to Port 

 Ventosa, by the Tuscarora, Commander Philip ; and also by 

 the ISTarragansett, Commander Dewey, along the same 

 coast from the boundary line of the United States to Cape 

 Corrieutes. The Jamestown, Commander Beardslee, made 

 a survey of the harbor of Sitka, Alaska, and marked a 

 number of channels with buoys and beacons. Whenever 

 the results of a survey that embraced any part of the coast 

 of the United States were received at the Hydrographic Of- 

 fice, such data were at once transmitted to the Coast Survey 

 Office. This course was required by the act of Congress 

 passed Juno 21, 1886, which placed the Superintendent of relations of 

 the Coast Survey directly in charge of the survey of theoffip e ro | i ^ p ^ 

 coast of the United States, including Alaska. The wor k^ st Suive y° f 

 of the Hydrographic Office was thus restricted to coasts 

 and waters outside the boundaries of the United States, yet 

 the navigating charts published by the Hydrographic Office 

 for the use of vessels entering or leaving our seaports have 

 necessarily represented the salient features of the coast of 

 this country. 



In the summer of 1879 the Hydrographic Office was re- Tl , insfer of th 

 moved from the " Old Octagon House" and transferred to ££ d '' (,sra P hi <> 



Oliico into the 



quarters in the new budding for the State, War, and Eavv5 uiIdin £ for 



T-v *. j. a ,. ,7 ^ nr, \ State. War, and 



Departments. A part ot the Office was, however, tempo- Kav y Depart- 

 rarily located in the old ¥avy Departmeut building. 



The meteorological charts were continued during thisyear, 

 and their sphere was extended to the JSTorth aud South At- 

 lantic Oceans. A number of the blank books sent out to 

 merchant vessels in the previous year were returned to the 

 office with the information desired. 



After completing the lines of deep-sea soundings across 

 the Atlantic, the Essex, Commander Schley, made an exam- ^amiaation of 

 ination of the approaches to the Eio de la Plata, and for- t0 tn'o eTtm 

 warded the results to the Office.
