REPORT OF THE SECRETARY. 61 



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

 Benedict accompanied the Fish Commission steamer Fish Hawk during an 

 exploration of the fishing banks in the Gulf of Mexico opposite Anclote 

 River, Florida. Mr. 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 Mollusks. 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 Museum 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. Maxon. 



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 Michigan. Mr. Charles Schuchert spent consider- 

 able time collecting fossils in Canada, also in the vicinity of Buffalo. X. Y.. in 

 Maryland, and in eastern Pennsylvania, the object of his inquiries being 

 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 ami abroad. In view of the small amount of money available for 

 purchases, this method of obtaining collections lias 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 abroad: 



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

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

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

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

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