previously represented in the collections were procured. The material 

 obtained included specimens of cone-in-cone structure, stylolites and 

 concretions, fossil ferns and a series of hydraulic limestones and cements. 

 A collecting trip was also made by the Curator of Geology among the 

 pegmatite regions of western Maine. A large number of valuable 

 specimens of the rare minerals of the region, such as toiumaline, colum- 

 bite, beryl, and herderite were procured, also some showy dendrites and 

 a striking series illustrating zonal weathering. The Assistant Curator 

 of Geology through a brief trip among most of the large porphyry 

 copper mines of New Mexico and Arizona secured a representative 

 though limited suite of the characteristic ores of this important new 

 development of the mining industry. The large mines visited on this 

 trip and from which specimens were secured were the Chino and Empire 

 Zinc mines in New Mexico, and the Copper Queen, Old Dominion, 

 Inspiration, and Miami mines in Arizona. At Grand Canyon, Arizona, 

 also, he obtained a ntmiber of specimens of Cretaceous fossils, copper 

 and silver ores and asbestos. 



Installation, Rearrangement, and Permanent Improvement. — There have 

 been placed on permanent exhibition in the Department of Anthro- 

 pology 90 new cases, most of these being completely labeled. The 

 material installed in these cases is distributed over the various 

 divisions as follows: African ethnology 27 cases; Melanesian ethnology 

 44 cases; American ethnology i case; American Archaeology 7 cases, 

 and Chinese pagodas 1 1 . The interesting Mexican pottery from Casas 

 Grandes presented by Mr. Homer E. Sargent has been installed in two 

 standard cases in the East Court. The recent acquisition of Navaho 

 blankets necessitated the reinstallation of a case of Navaho blanketry 

 in Hall 6. Progress has been made in the installation in standard cases 

 in the East Court, which, since the opening of the Musetim, has been 

 shown in the old Peabody cases from the World's Columbian Exposi- 

 tion. Fotir cases of the Hopewell material, from Ross County, Ohio, 

 are well along toward completion in Alcove 83 . The new arrangement 

 on shelves is very satisfactory, and brings out to advantage the scientific 

 value of this remarkable collection. The prehistoric pottery from 

 Chiriqui Republic of Panama, has been permanently placed on exhibi- 

 tion in two standard cases in Alcove 93 of the East Court. Costa Rican 

 archeology now in Alcove 84 is being prepared for permanent exhibi- 

 tion. All Peabody cases released, as the work of reinstallation pro- 

 gresses, are used for permanent storage in Halls 68 and 69 of the West 

 Annex in accordance with the plan outlined a year ago. For the 

 pVLTpose of preserving and photographing material, work has been done 

 in 138 exhibition cases. Installed cases of the Joseph N. Field collec-
