Glendive, Montana, and several additional specimens of moss agate 

 showing remarkable imitative landscape effects, loaned by him, furnish 

 excellent specimens of a remarkable occurrence of this mineral. Mr. 

 Fred Pattee contributed a number of specimens of ores and industrial 

 minerals from various western localities. These gifts included ores of 

 copper and vanadium, also specimens of phosphates, asbestos and barite. 

 An interesting series of copper ores showing stages of replacement of 

 hornblende by copper minerals was presented by Dr. F. C. Nicholas, 

 also a valuable specimen of tungsten ore. A striking and valuable 

 specimen of gold ore from the Smuggler-Union mine, Colorado, was 

 presented by Mr. T. S. Chalmers. The India Geological Survey pre- 

 sented several specimens of Indian laterite, thus securing a representa- 

 tion of this pecuHar mineral which had not hitherto been possessed. 

 The representation of the Los Angeles fossil faima was increased by 

 the gift of 532 specimens by Dr. WiUiam Bebb. These specimens 

 included several himdred bones of Smilodon, a large ntmiber of 

 bones of the fossil wolf and some of the fossil horse, sloth and bison. 

 The Colorado-Yule Marble Company presented six full-sized slabs 

 showing the varieties of marble obtained at its quarries. The col- 

 lection of fuller's earths and barites which had hitherto been 

 quite incomplete, was increased by the gift of specimens from several 

 firms producing these substances. Of these, fuller's earths were pre- 

 sented by the Manatee Fuller's Earth Corporation, the Floridin Com- 

 pany, J. E. and R. M. Famsworth and the Lester Clay Company; and 

 barite was presented by the Cherokee Chemical Company, Durex 

 Chemical Works, Krebs Pigment and Chemical Company, and Thomp- 

 son, Weinman and Company. Mr. H. R. Wood, the producer, pre- 

 sented four specimens of ttmgsten ore from Arizona, and C. K. WiUiams 

 and Company three specimens of crude and ground talc. Nine speci- 

 mens of iron ore from the imusual deposits that occur at Mayville, 

 Wisconsin, were presented by Mr. E. S. O'Connor. Mr. Max Ziege 

 presented 33 specimens of ores from the Ruby Moimtain District, 

 Nevada, which included copper, antimony and silver ores and accom- 

 panying rocks. Exchanges made with several individuals and institutions 

 resulted in adding desirable material. The most important accession re- 

 ceived in this way was obtained from the Deseret Museum, Salt Lake 

 City, Utah, and consisted of fifteen specimens of the products of the 

 Great Salt Lake, Utah, and fifteen briUiant and rare specimens of 

 crystallized pyrite and tetrahedrite from Bingham, Utah. The Salt 

 Lake products included brines, calcareous ooHte, mirabiHte and various 

 forms of common salt, all obtained from the waters of the lake. A slab 

 of the Big Skookum meteorite was obtained by partial exchange with
