DEPARTMENT OF GEOLOGY, 



The department of geology received 168 accessions aggregating 

 20,285 specimens, distributed among the several divisions and 

 sections, as follows: Systematic and applied geology, 586; mineralogy 

 and petrology, 4,983; invertebrate paleontology, 12,268; vertebrate 

 paleontology, 647; and paleobotany, 1,801. Excellent progress was 

 made in all branches of the work, including the classification and 

 arrangement of the reserve collections, the improvement of the 

 exliibition series, and the perfecting of the records of specimens, to 

 such an extent, in fact, as to place the department in much better 

 condition than at any previous time in its history. All of the col- 

 lections, with the exception of certain unworked material, have been 

 made readily accessible, and by means of systematic card catalogues, 

 which have been mostly brought down to date, the exact location of 

 any particular specimens may be quickly ascertained. 



Systematic and applied geology. — Among the more important 

 accessions to this division were a beautiful specimen of arborescent 

 copper free from gangue, and another showing the same occurrence 

 on a smaller scale in the original sandstone. They came from mines 

 near La Paz, Bolivia, and were received from the U. S. Geological 

 Survey. Exceptionally fine examples of zinc ores showing auri- 

 chalcite and smithsonite from the Tintic mining district, Utah, were 

 presented by the Yankee ConsoUdated Mining Company, of Salt 

 Lake City, through Mr. Victor C. Heikes. A series of radio-active 

 materials and products, assembled by Dr. George F. Kunz, of New 

 York City, and transmitted by him as a gift, includes specimens from 

 Sir William Crookes, of London, England, and Dr. Alexander Phillips, 

 of !^inceton University. A number of interesting laterite specimens 

 from various locaHties in India were obtained in exchange from the 

 Geological Survey of India. The additions to the meteorite collection 

 were as follows: Three nearly complete individuals of the Holbrook 

 meteoric stone which fell July 19, 1912, near Aztec, Ariz., donated 

 by Ml". F. C. Chekal, of Holbrook, Ariz. ; an excellent example of a 

 nearly complete individual of the Holbrook meteorite, weighing 1,120 

 grams, the gift of Mr. Clarence S. Bement, of Philadelphia, Pa., 

 through Prof. F. W. Clarke; an example, weighing 625 grams, of the 

 interesting brecciated meteoric stone which fell at St. Michel, Finland, 

 July 12, 1910, acquired through exchange with the Foote Mineral 

 Company, of Philadelphia, Pa.; and 18 fragments filling important 

 gaps in the exhibition series, purchased from IVIrs. Coonley Ward. 



The installation and labeling of the exhibition collections received 

 a proportionately large amount of attention. A work well advanced 

 and soon to be completed was the provision of group labels for the 

 cases in the section of applied geology, intended to broadly desig-
