REPORT OF NATIONAL MUSEUM, 1915. 57 



Several botanists of the Bureau of Plant Industry made extensive 

 collections of plants which have been deposited in the Museum. 

 Among these were 1,500 specimens of phanerogams obtained in west- 

 ern States by Mr. W. W. Eggleston, and 675 phanerogams from the 

 same region and western Canada secured by Dr. A. S. Hitchcock. 



DEPARTMENT OF GEOLOGY. 



The department of geology received 202 accessions, with a total of 

 134,044 specimens, distributed among the several divisions and sec- 

 tions as follows: Systematic and applied geology, 878; mineralogy 

 and petrology, 3,185 ; invertebrate paleontology, 129,718 ; vertebrate 

 paleontolog}^, 196 ; and paleobotany, 67. The miscellaneous material 

 sent in from various sources for examination and report amounted 

 to 515 lots, of which 282 consisted of minerals, 190 of geological 

 specimens and 43 of fossils. While the Museum is not equipped for 

 making detailed or quantitative analyses, simple determinations 

 generally suffice to decide the character and value of such rocks and 

 minerals as are submitted, and it may be further said that of all of 

 the specimens received in this connection during the year only 30 

 were of any interest to the department. 



Systematic and applied geology. — A collection illustrative of the 

 economic geology of the feldspar deposits of the United States, 

 described by Mr. Edson S. Bastin, and including material suitable 

 for exhibition, was deposited by the Geological Survey. Through 

 the personal solicitation of Mr. Frank L. Hess, of the same Survey, 

 a fine exhibition specimen of ferberite-bearing pegmatite from 

 Arizona was presented by Mr. S. H. Brockunier, of Nevada City, 

 Cal. ; two exhibition specimens of tungsten ore, by The Wolf Tongue 

 Mining Co., of Boulder, Colo.; a roscoelite-bearing sandstone from 

 the Primos Chemical Company's mine in San Miguel County, Colo., 

 by Mr. Harold Boericke, of Vanadium, Colo. ; and a sample of f erro- 

 vanadium, made from the patronite ores of Minasragra, Peru, by 

 The American Vanadium Co., of Pittsburgh, Pa. A contribution 

 from The Georgia Marble Co., of Tate, Ga., consists of four matched 

 slabs of marble, constituting an attractive wall panel; and another 

 from The Evans Marble Co., of Knoxville, Tenn., comprises two 

 matched slabs of the beautiful Eoseal marble, wdiich also form an 

 ornamental wall panel. 



The meteorite collection was enriched by gift, exchange and pur- 

 chase. Among the first were a slice of the Willamette iron, weighing 

 1,954 grams, from Mr. Clarence S. Bement, of Philadelphia, Pa.; 

 a 200-gram slice of the Delegate, New South Wales, iron, from the 

 Department of Mines, Sydney; a 160-gram slice of the Gilgoin stone, 

 from Mr. John C. H. Mingaye, of the same department ; and a 145-
