TBE GEOLOGICAL SOCIETY OF AMERICA 

 The Geological Society of America held 

 its twentieth annual meeting, December 30 

 and 31, 1907, at the University of New 

 Mexico, Albuquerque, N. M. The attend- 

 ance was small, of course, as compared 

 with that at the New York meeting, but it 

 was satisfactory and there was time for 

 considerable discussion. About thirty fel- 

 lows of the society were present, besides 

 other geologists, students and visitors to 

 the number of nearly as many more. 

 Seven members came from the CordiUeran 

 Section, which extends from the Rocky 

 Mountain region to the Pacific coast; five 

 members and three visitors came from 

 eastern Canada, and the remainder were 

 from the eastern half of the United States, 

 five of them being from the Atlantic coast. 

 The local arrangements for the meeting, 

 which were made by President W. G. 

 Tight, of the university, were admirable, 

 and the welcome extended by President 

 Tight and his associates and the citizens 

 of Albuquerque was most cordial and 

 substantial. Furthermore, the Atchison, 

 Topeka and Santa Fe Railway Company 

 made considerable reductions in the rates 

 for tickets, which were appreciated. The 

 meeting was held under the following 

 ofScers : 



President — President C. R. Van Hise, Madison, 

 Wis. 



First Vice-president — ^Mr. J. S. Diller, Wash- 

 ington, D. C. 



Second Vice-president — Professor A. P. Cole- 

 man, Toronto, Canada. 



SESSION OF MONDAY, DECEMBER 30, 1907 



President Van Hise presided, calling the 

 meeting to order at 9 :15 a.m. The secre- 

 tary, Dr. E. 0. Hovey, of the American 

 Museum of Natural History, reported that 

 the printed list of fellows contained 294 

 names. During the year the fourteen new 

 fellows elected at the New York meeting 

 qualified; two fellows. Professors Safford 

 and Heilprin, were lost by death, and one 

 was lost by resignation. After the read- 

 ing of the memorials of the deceased fel- 

 lows the regular program of papers was 

 taken up as follows: 



The Occurrence of Proustite and Argentite 

 at the California Mine near Montezuma, 

 Colo.: Frank R. Van Horn, Cleveland, 

 Ohio. 



Massive proustite and argentite occur 

 with argentiferous galena and sphalerite 

 in a gangue of siderite and quartz in a 

 fissure vein in gneissoid rocks at the Cali- 

 fornia Mine on Glacier Mountain, about 

 three miles from Montezuma, Summit 

 County, Colorado. The vein generally 

 shows a banded structure, but in places, 

 is more or less brecciated on account 

 of faulting of the region. The chief 

 ore is argentiferous galena, with consider- 

 able sphalerite irregularly mixed with it. 

 In some parts of the vein proustite and 

 argentite occur at the center in seams 

 which sometimes have a thickness of two 

 inches. In places the argentite has been 

 reduced to silver. 



The paper was discussed by C. R. Van 

 Hise, George D. Louderback and H. E. 

 Gregory.
