SCIENCE 



[N. S. Vol. XLI. No. 1050 



signed from tlie University of Chicago to join 

 the Harvard staff, vsrill have charge of this 

 new work, and during the summer of 1915 

 will establish a camp in the San Juan Moun- 

 tains of southwestern Colorado. Five weeks 

 of introduction will be given, beginning 

 early in August and closing about the tenth 

 of Septem.ber, and this course will be credited 

 at Harvard University towards a degree. 



The party will be limited in number, and 

 opened only to those men who have had at 

 least an introductory college course in geol- 

 ogy. Under the direction of Dr. Atwood the 

 party will actually conduct a piece of geolog- 

 ical survey work, and at the close of the sea- 

 son have the opportunity of an expedition 

 through the high mountain area. The field 

 chosen is remarkably rich in its range of geo- 

 logical phenomena, in mining interests, and 

 in scenic features. The equipment of the 

 camp is provided for by funds furnished by 

 the visiting committee of the department 

 which will reduce the cost to each student to 

 his share of the actual living and moving ex- 

 penses associated with the camp, and it is 

 estimated that these expenses will not exceed 

 one hundred dollars for each member. 



Applications for membership in this party 

 should be addressed to Wallace W. Atwood, 

 Harvard University, Cambridge, Mass., be- 

 fore May 1, 1915. 



The usual field work offered in Montana 

 and conducted under the endowment of Rob- 

 ert W. Sayles and under the direction of Pro- 

 fessor J. B. Woodworth will be offered during 

 the coming summer. That work will begin 

 early in July, and dose in time to permit 

 those who wish to join the Colorado party. 

 The combination of the two courses permits 

 the student to spend ten weeks under instruc- 

 tion in the Eocky Mountains during the com- 

 ing field season. 



The following members of the visiting com- 

 mittee were present at the meeting when these 

 plans were approved: Messrs. George B. 

 Leighton, George P. Gardner, Guerdon S. 

 Holden, Livingston Davis and J. Walter 

 Wood. 



THE 8UMMEM MEETING OF THE GEOLOG- 

 ICAL SOCIETY OF AMEBICA 



The society has accepted the invitation of 

 the authorities of the University of Cali- 

 fornia and Leland Stanford Jr. University to 

 hold a special meeting at Berkeley and Stan- 

 ford University, August 2-7, 1915, in affilia- 

 tion with the American Association for the 

 Advancement of Science. The following top- 

 ics have been selected for particular discus- 

 sion during the geological meetings: (1) 

 Erosion and deposition in arid climates; (2) 

 Diastrophism of the Pacific Coast; (3) Petro- 

 logical problems of the Pacific area. 



The sessions of Monday and Tuesday wiU 

 be held at the University of California and 

 that of August 4 at Stanford University. 



Excursions under the leadership of local 

 geologists wiU be organized during the re- 

 maining days of the week as follows : 



Thursday, August 5, to Point Eeyes Sta- 

 tion, Marin County, for an examination of 

 the San Andreas earthquake rift. 



Friday, August 6, to Mussel Rock, San 

 Mateo County, by the Ocean Shore Railway, 

 for an examination of Pliocene strata, the 

 type section of the Merced formation and 

 post- Tertiary defovmations of the coast. 



Saturday, August 7, two excursions wiU be 

 provided; one by the Oakland, Antioch & 

 Eastern Railway (electric) to Mount Diablo 

 for an examination of the Mount Diablo over- 

 thrust and the succession of Tertiary strata; 

 and the second to Santa Cruz by the Southern 

 Pacific Railway for an examination of up- 

 lifted marine terraces. 



More extensive excursions may be arranged 

 for the week following the meeting.
