REPORT OF THE SECRETARY. 61 



an expedition sent there by the U. S. Fish Commission, and Dr. J. E. 

 Benedict accompanied the Fish Commission steamer Fish Hawk during an 

 exploration of the fishing ]>anks in the Gulf of Mexico opposite Anclote 

 River, Florida. ]\Ir. J. B. Henderson, jr., of Washington, who has on 

 many former occasions manifested his interest in the ^Museum, made at 

 his own expense a collecting trip to Haiti and Jamaica, taking with him 

 Mr. C. T. Simpson, of the Division of MoUusks. Much valuable mollus- 

 can material was obtained. 



Messrs. Barton A. Bean and William H. King collected fishes at Key 

 West, Fla. The explorations in Cuba for the Pan-American Exposition, 

 begun in 1900 by ^Messrs. Palmer and Riley, also of the ^luseum staff, 

 were completed early in the year. Botanical explorations with interest- 

 ing results were conducted in the Southern States by Messrs. C. L. Pollard 

 and W. R. INIaxon. 



Important accessions through explorations by the Geological Survey 

 have already been alluded to. Mr. F. A. Lucas, of the Museum, and Mr. 

 Alban Stewart visited several localities where mastodon bones had been 

 reported, with the object of securing a skeleton for the Pan-American 

 Exposition. Only a single fairly preserved one was obtained, however, in 

 a locality in southern ]\Iichigan. Mr. Charles Schuchert spent consider- 

 able timecollecting fossils in Canada, also in the vicinity of Buffalo, N. Y., in 

 ^laryland, and in eastern Pennsylvania, the object of his inquiries l^eing 

 to secure data for fixing more definitely the line separating the Silurian 

 and Devonian systems in America. 



Exchanges. — Much material had been received through the exchange of 

 duplicate specimens with scientific establishments and individuals both at 

 home and abroad. In view of the small amount of money available for 

 purchases, this method of obtaining collections has become of considerable 

 importance, especially with reference to foreign countries, from which 

 gratuitous contributions are rarely to be expected and to which the scien- 

 tific explorations of this Government seldom extend. Transactions of this 

 character were conducted through the year with the following institutions 

 and individuals aljroad: 



Royal Botanic Gardens, Kew, England; Museum of Natural History, 

 Paris, France; Musee de St. Germain, Seine-et-Oise, France; Zoological 

 ^luseum, Copenhagen, Denmark; Museum Senckenberg, Frankfort-on- 

 the-Main, Germany; Royal Zoological and Anthropological-Ethnograph- 

 ical ^Museum, Dresden, Germany; Geological Institute of Kiel, Germany; 

 Museum of Natural History, Berlin, Germany; Zoological INIuseum of the 

 University of Upsala, Upsala, Sweden; Museum of the Imperial Academy 

 of Sciences, St. Petersburg, Russia; Royal Geological Museum, Leiden, 

 Holland; Royal Zoological [Museum, Turin, Italy; Royal Botanic Gardens,
