DREDGING AND HYDROGRAPHIC RECORDS OF 



2. CRUISE IN THE EASTERN PACIFIC. 



From October 6, 1904, to February 24, 1905, the Albatross, in 

 charge of Mr. Alexander Agassiz, was detailed for investigations in 

 the eastern Pacific in the region lying between Panama, Callao (Peru), 

 Easter Island, and the Gambier Islands. This was the vessel's second 

 cruise in these waters, similar explorations, also conducted by Mr. 

 Agassiz, having been made in 1891. Much interest attaches to this 

 work, be.cause there is no other oceanic region situated at so great a 

 distance from a continental area and interrupted by so few islands. 

 The eastern tropical Pacific extends south from a line between Aca- 

 pulco and the Galapagos and to Cape San Francisco as a northern 

 boundary, to a distance of over 3,000 miles, as far as the latitude 

 of Manga Reva, Easter Island, and a point, north of Valparaiso. 

 The distance from Manga Reva to the South American coast is fully 

 3,500 miles, with nothing to break this vast expanse of water. (Gen- 

 eral Report of the Expedition, by Alexander Agassiz, Memoirs of the 

 Museum of Comparative Zoology, vol. xxxviii, 1906.) 



The collections are rich in material for studies of oceanic fauna 

 and bottom deposits, and they include also some plants from Manga 

 Reva and Easter Island which possess much interest in a considera- 

 tion of the origin and distribution of the flora of the eastern Pacific.
