Copper 177,595,888

So far as fuels are concerned the work of 

 the Geological Survey is divided into three 

 classes, geologic, technologic and statistical, 

 the last of which is in charge of the Division 

 of Mineral Resources, whose work for 1906 

 yielded the figures given above. All the 

 geologic work on mineral fuels of the United 

 States is under the general supervision of Mr. 

 M. R. Campbell. The work is of various 

 grades and degrees of precision, depending on 

 the needs of the public and the conditions 

 under which the surveys are carried on. In 

 the region west of the one hundredth meridian 

 the coal fields are comparatively unknown and 

 the work of the survey is largely exploratory. 

 Rapid reconnaissance surveys are made over 

 large areas to determine the limits of the field 

 and to obtain such information regarding the 

 number and character of the coal beds and 

 their attitude as may be possible in the present 

 undeveloped condition of the field and with 

 the hasty method of examination. In the 

 eastern fields information is needed almost as 

 badly as in the west, but the work is of a much 

 more detailed character and involves not only 

 a thorough study of the geologic conditions 

 under which the coal occurs, but also a study 

 of the quality of the coal and its adaptability 

 to various commercial uses. 



Messrs. Sotheby, Wilkinson and Hodge 

 have, as we learn from the London Times,

 India," 1862, the author's own copy prepared 



for a new edition, with the collection of draw- 

 ings made by the author to illustrate his book 

 and also the original MS.— £250 (Grote) ; an 

 extensive collection of about 1,000 English 

 and foreign pamphlets, chiefly botanical, 

 formed by Dr. Masters and bound in 131 

 volumes— £38 (Wheldon); 0. Loddiges, The 

 Botanical Cabinet, 1818-33, 20 volumes, with 

 2,000 colored plates— £27 10s. (Quaritch) ; and

UNIVERSITY AND EDUCATIONAL NEWS 



Mr. John D. Rockefeller has added $2,- 

 191,000 to his previous gifts to the University 

 of Chicago, making the total amount of these 

 nearly $24,000,000. Of Mr. Rockefeller's re- 

 cent gift, the sum of two million dollars is 

 for permanent endowment; the sum of $155,- 

 000 is to meet the deficit for 1907, and the 

 sum of $36,000 is for miscellaneous purposes. 



Colorado College has completed an addi- 

 tion of $500,000 to its productive funds, to- 

 wards which the General Education Board and 

 Mr. Andrew Carnegie each contributed $50,- 

 000. The town of Colorado Springs raised 

 $50,000 toward the fund in two weeks. 



Miss Katherine Greenhill has bequeathed 

 to Trinity College, Oxford, about $3,000 to 

 found an exhibition for a medical student in 

 memory of her father, the late William Alex- 

 ander Greenhill, M.D., of Oxford. 



The French government will build a college 

 for women at St. Germain-en-Laye. 



Miss Laura D. Gill has resigned the dean- 

 ship of Barnard College, Columbia University. 

 Dr. William T. Brewster, professor of English, 

 is acting dean. 



Dr. Edwin G. Conklin, since 1896 professor 

 of zoology in the University of Pennsylvania, 

 has accepted the chair of biology in Princeton 

 University. It is understood that Princeton 

 University has offered Professor Conklin un- 

 usual facilities for his research work as well 

 as a larger salary than is received by any 

 professor at the University of Pennsylvania.
