REPORT OF ASSISTANT SECRETARY. 37 



the first steam engine set up on the Western Continent, having been 

 imported from England in 1753 for pumping water from the copper 

 mines of Col. John Schuyler, Belleville, New Jersey. A very useful 

 addition to the time-keeping series consists of two clocks from the 

 Chelsea Clock Company, of Boston, which have been connected with 

 the service of the U. S. Naval Observatory. Interesting historical 

 relics deposited by the Society of the Daughters of the American 

 Revolution have been added to the cases assigned to that society. 



Several groups of ethnological lay figures returned from recent 

 expositions have been installed wherever a place could be found for 

 them, some having been arranged in the lecture hall. 



With a view to unifying the work of installation in the Department 

 of Biology, this entire subject was placed in charge of Mr. F. A. Lucas, 

 the curator of comparative anatomy. But little was done toward 

 preparing new exhibits in this department, however, owing to the 

 arrangements in progress for the St. Louis Exposition. Some of the 

 more valuable birds were remounted, and four groups of game birds 

 were installed in two new special cases at the entrance to the Smith- 

 sonian building. Additional casts of fishes for the series in the south- 

 east range of the Museum building are being prepared, and a beginning 

 has been made toward the installation of a series of specimens illus- 

 trating the mollusk fauna of the District of Columbia, one such case 

 having alreadj^ been completed. The installation of the systematic 

 series of insects has been nearly finished. 



A series of illustrations of corals and coral reefs from Saville Kent's 

 work on the Great Barrier Coral Reef of Australia has been framed 

 and placed with the exhibition of corals in the west hall of the Smith- 

 sonian building. Many specimens in the different exhibition collec- 

 tions have been renewed, and there is a generally improved appearance 

 in nearly all the exhibits of this Department. 



To the display collection in the Department of Geology have been 

 added skulls of JJiplodocus, Trac/todon, and of two genera of Cerat<>j>- 

 sia, one being the type of Triceratops caMcwviis and the other repre- 

 senting a new genus of the dinosaurs. The mounted skeleton of a 

 specimen of Syornis casuarinus from New Zealand has also been 

 installed. 



A noteworthy addition to the exhibits in geology is a geological sec- 

 tion on a scale of 2 miles to the inch across the United States from the 

 coast of North Carolina to a point near San Franeisco. This model 

 has been the work of two years. The specimens in all other divisions 

 of this department have been more or less overhauled during the 

 year, especially in the lithological and mineralogical series, and 

 improvements have been made in the exhibit of invertebrate fossils, 

 but lack of room prevents any noteworthy additions to or expansion 

 of these collections.
