FISCAL TEAR ENDING JUNE 30, 1873. 



During this year, a running survey was made of the east 

 coast of Mexico, from the mouth of the Ooatzacoalcos to 

 that of the Rio Grande, by the U. S. S. Wyoming, Com- 

 mander F. H. Baker ; surveys were also made by our ves- 

 sels in the West Indies, on the east coast of South Amer- 

 ica, and in the Gulf of California. The Portsmouth, Com- 

 mander J. S. Skerrett, was employed in investigating dan- 

 gers between the Sandwich Islands and our Pacific coast, 

 and made special surveys of Palmyra, Washington, and Reports of sur-

Christmas Islands. The Narragansett, Commander George by navai vessels. 



Dewey, made a running survey of the coast from San Diego 



to Cape Corrientes. The Tuscarora, Commander George 



E. Belknap, was employed in taking deep-sea soundings in 



the Pacific ; and accurate depths were ascertained along a 



line 1,000 miles in length, extending from Puget Sound 



toward the island of Atcha in the Aleutian group. 



Upon the breaking out of the Civil War, the plan adopted 

 by Maury of soliciting meteorological data from merchant 

 vessels, for the construction of charts, was discontinued. 

 But in 1873, it was decided to again commence the collec- 

 tion of information from merchantmen, and from our men-, 

 of-war, for the purpose of accumulating matter for a new 

 edition of Maury's Charts, and requests for such data were 

 accordingly sent out to the Navy and merchant marine. 



In addition to the hydrographic work performed by naval 

 vessels before mentioned, reported dan/iers were invest! 

 gated, and special surveys of islands, harbors, coasts, &c, 

 were made by our ships on foreign stations, and all results, 

 as fast as received at the Office were published and sent out special sur- 

 for general information. (Report of Secretary of the Navy, by^avaw'essefs 6
