The second annual announcement of intercollegiate summer courses in field geology has recently been issued. Next summer 11 colleges and universities will give courses which may be counted towards a degree by qualified students in 28 colleges and universities. Harvard is included in this arrangement.

The most important feature of the plan is a five weeks' course on the geology of the Appalachian region to be conducted by professors from five different universities. Each instructor will conduct the class over some district with which he is particularly familiar. The program for this course will be as follows:

July 3 to 8.--Professor W. B. Clark of Johns Hopkins University. "The Tertiary and Cretaceous Strata of the Coastal Plain of Maryland."

July 10 to 15.--Professor W. M. Davis of Harvard. "The Folded Paleozoic Strata of the Susquehanna Juniata District of Pennsylvania."

July 17 to 22.--Professor T. C. Hopkins of Syracuse University. "The Horizontal Paleozoic Strata and Glacial Features of Central New York."

July 24 to 29.--Professor H. P. Cushing of Western Reserve University. "The Faulted Crystalline and Paleozoic Rocks of the Little Falls District, New York."

July 31 to August 5.--Professor J. Barrell of Yale University. "The Meta- morphic and Triassic Rocks of Western Connecticut."

Besides Professor T. A. Jaggar's expedition to Iceland, previously announced, Harvard will give two courses in field geology. Assistant Professor J. B. Woodworth will conduct a course in general field geology in southeast Montana, beginning July 10. In this course particular attention will be devoted to the geological column and the identification of formations by means of fossils.

Professor Shaler and Assistant Professor Woodworth will conduct a course in the Rocky Mountains in field research and methods of professional geological field-work. The income of the fund of the Josian Dwight Whitney scholarship, yielding two scholarships of $100 each, is available for members of both these courses, whether or not Harvard students. Applications for these two scholarships should be sent before May 25 to Professor W. M. Davis, 17 Francis avenue.

Information as to requirements, expenses, and all other details of these and the other courses is contained in the "Joint Announcement of Field Courses in Geology," which may be obtained at the Publication Office, University 2
