REPORT ON THE LABORATORY OF PHYSICAL 



GEOGRAPHY. 



By Professor W. M. Davis. 



During the Academic year 1893-94, the courses in Physical 

 Geography and Meteorology have been conducted on the same 

 plan as in previous years. Mr. Ward has continued to act as 

 Assistant in the course in Meteorology, but has withdrawn from 

 the course in Physical Geography, in order to give more of his 

 time to editing the American Meteorological Journal, which has 

 now been in his charge over two years. Mr. Griswold has acted 

 as Assistant in Physical Geography, in addition to his duties in 

 connection with the course in Field Geology. 



The more advanced courses have been attended by six students, 

 of whom four were college graduates. The special subjects studied 

 were as follows : Mr. Abbe, the topographical development of shore 

 lines, with special reference to the features of our Atlantic coast ; 

 Mr. Daly, the development of escarpments ; Mr. Gulliver, the 

 topographical criteria of the elevation or depression of the land ; 

 Mr. Marbut, the flood-plain of the Mississippi ; Mr. Schraeder, the 

 Great Plains of the West ; Mr. White, the effect of local topography 

 on the general winds, and the features of Arctic climate. 



A gift of great value has been received from the Geographical 

 Service of the French Army. The large series of geodetic and 

 topographic maps of France and Algeria and the exquisite model 

 of the valley of the upper Moselle, exhibited at the World's Fair 

 at Chicago, were by direction of the Chief of the Service pre- 

 sented to the United States Coast and Geodetic Survey and the 

 Harvard Laboratory of Physical Geography. The collection was 

 divided by conference with the Superintendent of the Coast and 

 Geodetic Survey, and a number of valuable maps, as well as the 

 model, remain to enrich our collections.
