ANNUAL REPORT OF THE 



Professor Davis was absent during the first half-year and a part 

 of the second, as Exchange Professor at the University of Berlin, 

 and Professor Woodworth was absent during the first half-year, 

 in charge of the Shaler Memorial Expedition. Professor Davis's 

 late return (April, 1909) necessitated the withdrawal of Geology 



7 2hf, a course announced for the second half-year, and emphasized 

 the fact that the absence of members of the teaching staff for part 

 of the year, as Exchange Professors, may seriously handicap the 

 Departments, however advantageous in other ways. 



Geology 18 (Economic geology of the non-metalliferous sub- 

 stances), formerly given by Professor H. L. Smyth, was rearranged 

 and given as a half-course during the first half-year by Professors 

 Wolff, Woodworth, and Palache. In Professor Woodworth's 

 * absence, Geology 4 1/i/was given by Professor Wolff, and Geology 



8 Ihfby Dr. G. R. Mansfield. Dr. Mansfield resigned his position 

 as Instructor at the end of the first half-year, to accept an Assis- 

 tant Professorship of Geology at Northwestern University. The 

 Department has been greatly strengthened by the addition to its 

 staff of Professor A. Lawrence Rotch. Professor Roteh's course 

 of research in meteorology (Geology 20/) is given at Blue Hill 

 Observatory, and the resources of this splendidly equipped meteor- 

 ological observatory have thus become available for the use of 

 properly qualified students. The instruction in meteorology and 

 climatology is now much more complete and better systematized 

 than ever before. 



Details regarding the courses of instruction will be found in the 

 accompanying reports of the Departmental staff. Messrs. J. W. 

 Eggleston, J. E. Hyde, W. P. Hayhes, F. H. Lahee, W. G. Reed, Jr., 

 and B. M. Varney were assistants during the year. 



The permanent maintenance of a summer course in geological 

 field work in the Rocky Mountains is a matter of great importance, 

 and a considerable share of the funds of the Department has 

 lately been devoted to the support of this course. It is, therefore, 

 with peculiar satisfaction that the Chairman reports that the Uni- 

 versity has received an anonymous gift of $5,000. to establish a 

 fund, the annual income of which is to be used for the support of 

 a summer field course in structural or stratigraphical geology, 

 conducted preferably in the mountain region of western North 

 America, for the benefit of students who have an elementary
