FISCAL TEAR ENDING JUNE SO, 1874. 



A Meteorological Journal was prepared in the Office and 

 issued to merchant vessels and others for their greater con- 

 venience in recording information for the correction and con- 

 Meteoroiogicai tinuance of the " Wind and Current Charts." The survey 



merchant SSU ves°of the Pacific, along the coasts of the peninsula of Lower 

 California, in the Gulf of California, and around the Re- 

 villa Gigedo groups of islands, was continued by the Nar- 

 ragansett, under Commander Dewey ; but the want of 

 an adequate appropriation for carrying on the survey 

 made it necessary to withdraw the Portsmouth from hydro- 

 Reports of sur- graphic work. The Fortune, under Lieut. Commander F. 



by y nav^'ves8efs e M. Green, completed the running survey of the east coast 

 of Mexico, begun in the preceding year by the Wyoming, 

 and in addition made a series of offshore soundings along 

 the Mexican coast ; while the Tuscarora finished her deep- 

 sea soundings in the Pacific. 



A survey of the mouth of the Rio" cle la Plata was made 

 •by the officers of the Wasp, on the South Atlantic Station, 

 and vessels on other stations made similar surveys, or in- 

 vestigations, generally at the suggestion of the Hydrog- 

 rapher. Results of such surveys, made by the Shawmut, 

 Commander H. L. Howison ; the Kansas, Commander A. 

 V. Reed, and the Wasp, Commander A. T. Mahan, were re- 

 ceived at the Hydrographic Office within the year, and pub- 

 lished as soon afterwards as practicable.
