74 REPORT OF NATIONAL. MUSEITM, 1925 



views, was presented to the National Museum. They are un- 

 doubtedly the best and most attractive additions to the collections 

 of physical geology received during the year. 



The most important materials in point of number and desirability 

 in the field of applied geology were secured by Assistant Curator 

 Foshag while on detail with a United States Geological Survey 

 party. In addition to a large amount of mineralogical material 

 noted elsewhere, his collections included ores needed to fill out the 

 series. 



Among other accessions the following may be noted: From the 

 White Caps Mining Co., Tonopah, Nev., through John J. Kirchen, 

 president, a large specimen of very well crystallized stibnite supe- 

 rior in quality to anything heretofore received from an American 

 locality. From the Mar-John Mining Co., Sheepranch, Calif., 

 through Frank L. Hess, a large mass of cobalt ore. Mr. Hess was 

 also influential in obtaining from A. J. Richards, Albany, Wyo., 

 as an exchange, two large masses of the rare silicate allanite which, 

 while not striking in the rough form, were made very attractive by 

 polishing. J. E. McKeever, Castleton, Utah, contributed a large 

 exhibition specimen of vanadium ore consisting of carnotite and 

 hewettite in sandstone, from Polar Mesa, Utah. C. M. Snyder for- 

 warded a specimen of bismuth-silver-gold ore from the Missouri 

 mine. Halls Valley mining district, Colo., and A. E. Heighway 

 added to the series of arsenic ores a specimen of arsenopyrite from 

 Vermont. The most notable accession from a foreign locality is a 

 gold ore from the Passagem mine, Minas Geraes, Brazil, received 

 from Capt. Hugh Barclay of the American Embassy at B-io de 

 Janeiro. With the one exception noted as an exchange, these are all 

 recorded as gifts. 



Several objects of onyx marble (travertine), including a stand 

 for drop light, jewel box, paper weight, marbles, and balls for auto- 

 mobile gear shift levers have been presented by the Yavapai Onyx 

 Mining Corporation, Dubuque, Iowa, and the California Agate Co., 

 Huntington Park, Calif. These illustrate new uses for a well known 

 stone. 



As usual, several sets of specimens illustrative of reports by mem- 

 bers of the United States Geological Survey were officially trans- 

 ferred by that institution for permanent preservation. These in- 

 cluded collections illustrating a monographic report on the Lead- 

 ville district, Colo., not yet published ; a collection of rocks and ores 

 from the Manhattan district, Nev., illustrative of Bulletin Y23, by 

 H. G. Ferguson; a collection of rock and ore specimens illustrating 

 a report on the Saddle Mountain and Banner mining districts of 

 Arizona; miscellaneous collections including diamond-bearing peri- 

 dotite, minerals from the De Queen, Caddo Gap, and Hot Springs
