Mr. C.H. White, instructor in mining and metallurgy, will conduct a summer course in geological field work in the San Juan and Needle Mountains of southwestern Colorado, beginning August 15 and ending September 23. The members of the course will meet in St. Louis, and will first make an excursion through New Mexico, Arizona, and southern California to the Pacific coast, returning through Nevada and Utah, to study some of the larger geological features in the region traversed. Those who give five weeks to field study and submit a satisfactory report may receive credit for a half-course. The total expense of the trip, including fee for the course, will be about $221. All who wish to go should make application for enrolment to Mr. C.H. White, Rotch Building, before July 1, giving a brief statement of their previous geological training.
