6 inches long, 2 feet broad, and 2 feet thick, 

 and weighs nearly a ton. It is an ore char- 

 acteristic of the Boulder tungsten field — a 

 brecciated ixjgroatite and granite cemented by 

 quartz and ferberite. 



The second is a large specimen of the newly 

 discovered mineral tungstenite (tungsten sul- 

 phide), a gift from Wm. Barrett Eidgely, of 

 New York City. Timgstenite is a soft, lead- 

 gray mineral, looking very much like fiue- 

 flaked molybdenite and carries some 44 per 

 cent, timgsten. The specimen, which contains 

 an admixture of some galena and quartz and 

 ■weighs more than 100 pounds, is from the 

 Emma mine at Alta, Utah. This mineral was 

 identified only last December by R. C. Wells 

 and B. ' S. Butler, of the United States Geo- 

 logical Survey, and almost simultaneously by 

 K. D. Kuhre and Mr. J. J. Beeson, the geolo- 

 gist at the mine. 



The third, and in some ways the most re- 

 markable specimen, is a mass of scheelite (cal- 

 ciiun tungstate) from the Union Mine of the 

 Atolia Mining Co., Atolia, California. This 

 mine is undoubtedly the richest and largest 

 6cheelite mine ever discovered, and the spec- 

 imen is correspondingly large. It is a section 

 across the main part of the vein and is 4 feet 

 8 inches long, about 2 feet 6 inches wide, and 

 2 feet thick. Some granodiorite, the country 

 rock, is inclosed. The specimen weighs 2,600 

 pounds and carries possibly 30 per cent. WO,, 

 so that it contains in the neighborhood of 700 

 pounds of metallic timgsten and is worth, at 

 the present price of ore, nearly $2,000. Great 

 care was needed to remove the specimen from 

 the mine intact, a work which was carried on 

 under the supervision of Charles S. Taylor, 

 one of the discoverers of the mine and now its 

 superintendent. 



CHEMISTRY AT YALE UNIVERSITY 



It has been arranged at Yale University to 

 unite the staffs and laboratories of the under- 

 graduate departments of the college and of the 

 Sheffield Scientific School in a single depart- 

 ment. On this plan the Yale Alumni Weekly 

 coimments as follows: 



The article which we publish in this number on 

 the coordination of chemistry teaching in the col- 



li ge and Sheffield marks a move in what we have 

 good reason to believe will shortly become a general 

 reorganization at the university on a new and co- 

 operative departmental basis. Until now chemistry 

 at Yale has been divided into two distinct and im- 

 related parts, with its two separate faculties and 

 student groups, its two separate laboratories and 

 equipments, its two separate financial systems, its 

 two separate heads. It has furnished a striking 

 instance of the historical cleavage between the 

 Sheffield Scientific School and Yale College, with 

 all the attendant lack of cooperation and sympa- 

 thetic understanding which that cleavage has for 

 so many years resulted in. If any criticism of 

 Yale 'a educational organization has been unan- 

 swerable, for years it has been this continued sepa- 

 ration between its two undergraduate schools in 

 the teaching of common subjects. It has split 

 Yale into two— on occasion even hostile — camps. 

 It has hindered scientific progress in both schools. 

 It has broken up at the start any possible unity of 

 educational policy which might have been accom- 

 plished. 



Until now it has seemed impossible to find a way 

 to end this illogical and harmful cleavage between 

 Sheff and the college in their educational organiza- 

 tion. But the war, which is subtly undermining a 

 good many of our ancient prejudices, both individ- 

 ual and institutional, has begun to play its deciding 

 part in this historic Yale question. The hours of 

 classroom exercises have recently been made to con- 

 form for the undergraduates of both Shoff and the 

 college. The departments of chemistry have now 

 found it necessary to reorganize to meet the new 

 conditions, and, in reorganizing, have found it pos- 

 sible and even desirable to cut the old Gordian knot 

 of departmental prejudices and consolidate as a 

 university department. When this new plan goes 

 into effect, Yale will have made its first definite 

 move in what we believe will be a much more gen- 

 oral trend in the near future, toward operating its 

 educational machinery as one university organiza- 

 tion rather than as two separated undergraduate 

 departments. 



In an article on the subject in the Yale 

 Alumni Weekly Professors Bertram M. Bolt- 

 wood and Treat B. Johnson mention as the 

 greatest needs of the university in chemistry: 

 (1) an adequate endowment for research, (2) 

 the appointment of research professors in each 

 department to organize and direct, (3) opportu- 

 rities to give greater encouragement to our 

 younger men to carry out research work, (4)
