During July and August twenty-one courses will be given by the Harvard Summer Schools. There will be one in Anglo-Saxon, to begin July 2d, and continue six weeks, and one in Botany, which will begin June 29th and close August 1st. The latter will consist of two parts, the first to deal with Vegetable Physiology, etc., and to consist primarily of practical laboratory work, and the second to be a course of daily lectures on special topics. There are to be four Chemistry courses: General Chemistry; Quantitative Analysis; Qualitative Analysis; and Organic Chemistry. The one course in English will be about equivalent to the required English of the freshman year. Two courses will be presented in Field Engineering, one in Topography, and one in Railroad Surveying. Actual practice will be given in the first, in leveling, determination of grade, etc., and in the second, a railroad of from three to five miles in length will be surveyed, with estimates, bills of materials, contracts, etc., for the same. Both of these courses begin June 29th and last six weeks.

Two courses in French and two in German will be given, corresponding to courses A and 1a in each subject, in the regular college work. They begin July first and continue six weeks. There are to be three courses in Geology. The first is elementary, treating of General Physical and Structural Geology. It is to begin July 6th and close Aug. 7th. Daily lectures are to be given, supplemented by laboratory work. Afternoons are to be spent in excursions in the immediate neighborhood of Cambridge, and sometimes an entire day will be spent on a more distant trip. The second of the three courses consists of advanced field work and investigation. It will begin July 13th, at Utica, N. Y., and will close at some point on the Atlantic coast, August 22d. Utica, Catskill, N. Y., Meriden, Connecticut, and the Delaware Water Gap will be the different head-quarters from which excursions will be made. The third course will consist of advanced individual study, and the work will be carried on chiefly in New England, Eastern New York, and New Jersey.

There will be two courses in Physics, the first, elementary, equivalent to Physics B in the college, and the second, advanced, equivalent to Physics C. The first lasts from July 6th till August 10th, and the second from July 6th till August 14th. A course in Physiology and Hygiene, one in Physical Training, and a series of thirty lectures on the methods of instruction in the several departments in which all these courses belong complete the catalogue of summer work.

All the courses, excepting the two advanced ones in Geology, and those in Field Engineering are to be given in the college buildings in Cambridge. Fuller information can be obtained by application to the Secretary of the University.
