of large size, skins alone numbering 8,691. The unqualified 

 success of the Expedition as a whole was unquestionably due 

 to the ability and sagacity of its leader, Mr. R. H. Beck. 



The personnel of the Expedition was as follows: R. H. 

 Beck, chief; Alban Stewart, botanist; F. X. Williams, ento- 

 mologist; W. H. Ochsner, geologist and conchologist ; J. R. 

 Slevin, herpetologist ; J. S. Hunter and E. W. Gifford, 

 ornithologists; E. S. King, assistant herpetologist; F. T. 

 Nelson, mate; J. J. Parker, navigator; J. W. White, cook. 

 The scientific members of the Expedition shipped in the 

 capacity of seamen, so that in addition to collecting, the duties 

 attending the working of the vessel likewise fell in a large 

 measure to their lot. 



The schooner "Academy," of eighty-seven tons burden, 

 sailed with the Expedition from San Francisco on June 28, 

 1905, returning on November 29, 1906, after an absence of 

 seventeen months and one day. During the southward voyage 

 ten stops were made, while on the home voyage from Culpep- 

 per, Galapagos Islands, to San Francisco none were made. The 

 home voyage was a slow one of sixty-five days. On the 

 voyage south, short stops were made during the month of 

 July, 1905 : at Ensenada, San Martin Island, San Geron- 

 imo Island, San Benito Islands, Cerros Island, and 

 Natividad Island, Baja California; and at San Bene- 

 dicto and Socorro, Revilla Gigedo Islands. August 

 10 was spent on Clipperton Island, Mexico, which was 

 reached only after many days of beating against contrary 

 winds and currents. The early part of September, 1905, was 

 spent at Cocos Island, Costa Rica. On September 13, the 

 schooner set sail from Cocos with the Galapagos Islands as 

 her destination. No intermediate stop was made; although 

 two days were spent sailing down the coast of Ecuador from 

 Perdenales in the Province of Esmeraldas, to Manta and Cape 

 San Lorenzo. At Manta, on September 19, the schooner was 

 put on the westward tack, and stood out along the north coast 

 of the great headland. Hood Island, the southernmost of the 

 Galapagos group, was reached at 9 A. M., September 24, after 

 less than four days' voyage from Manta. 



When calm weather afforded the opportunity, a great deal 

 of collecting was done on the ocean, both on the outward voy- 

 age and on the homeward voyage, during our numerous jour-
