Over $3,000,000 worth of abrasive mater- 

 ials were produced in the United States last 

 year. All branches of the abrasive industry- 

 showed notable growth except the millstone 

 and the grindstone industries, according to 

 W. C. Phalen, of the United States Geolog- 

 ical Survey, in an advance chapter from 

 Mineral Eesources of the United States, 1910. 

 The total estimated value of all the abrasive 

 materials consumed in this country last year 

 was $4,234,662, of which $3,010,835 worth were 

 of domestic production. Abrasive materials 

 may be divided into two classes — natural and 

 artificial. The production of artificial abra- 

 sives has shown great increase since they 

 were first made, less than 15 years ago, and at 

 the present time it exceeds that of the nat- 

 ural abrasives. During 1910 natural abra- 

 sives valued at $1,406,805 were produced in 

 21 states. Of these materials, grindstones 

 and pulp stones led with a production valued 

 at $796,294. The production of burrstones 

 and millstones in the United States in 1910 

 was valued at $28,217. The production of oil- 

 stones and scythe stones amounted to $228,- 

 694, compared with $214,019 in 1909. Garnet 

 is one of the very hard minerals, and is ex- 

 tensively used as an abrasive. The production 

 of abrasive garnet in 1910 amounted to 3,814 

 short tons, valued at $113,574. This was an 

 increase of 842 tons, or 28 per cent., in quan- 

 tity, and of $11,259, or 11 per cent., in value. 

 In the class of artificial abrasives are in- 

 cluded carborundum, alundum and crushed 

 steel. The production of artificial abrasives 

 in 1910 showed an increase of 2,559,000 

 pounds in quantity and of $238,210 in value, 

 as compared with 1909. 



UNIVESSITY AND EDUCATIONAL NEWS 

 The class of 1886 has presented to Harvard 

 University $100,000, the income of which is to 

 be used for the benefit of the college. From

 sity has received $25,000 for the establishment 

 of scholarships in memory of his nephew 

 Clemen Harlow Condell.

 the preceding day an educational conference 

 was held. 



Messrs. J. B. Duke and B. N. Duke have 

 made further gifts amounting to $228,000 to

 Butler of Columbia, Schurman of Cornell and 

 Einley of the New York City College will be 

 among the speakers. 



Professor James William Toumey, who has 

 acted as head of the Yale Forest School during 

 the absence of Professor Graves, has been 

 elected director for the year 1911-12. 



William H. Emmons, associate professor of 

 economic geology and mineralogy at the Uni- 

 versity of Chicago, and geologist for the 

 United States Geological Survey, has been ap- 

 pointed head of the department of geology at 

 the University of Minnesota. 



A. C. Trowbridge, instructor in geology at 

 the University of Chicago and assistant geol- 

 ogist of the Illinois Geological Survey, has 

 been appointed professor of geology at the 

 State University of Iowa. 



As a result of the resignations of Professor 

 E. A. Harper, Dr. W. G. Marquette, assistant 

 professor, and A. B. Stout, instructor, in the 

 botany department of the University of Wis- 

 consin, who have accepted places at Columbia 

 University, the regents of the state university 

 have appointed E. M. Gilbert, assistant pro- 

 fessor of botany; W. N. Steil, E. T. Barthole- 

 mew and Alban Stewart, instructors in botany, 

 and A. G. Johnson, assistant in botany. 



At the University of Wisconsin E. Baum- 

 gartner has been appointed instructor in anat-
