convenient than usual. Among the subjects studied in the ad- 

 vanced course was the historical development of the content and 

 method of treatment of Physical Geography, as indicated by text- 

 book and treatises since 1800, from which a valuable suggestion 

 was gained as to the direction of future progress ; this work hav- 

 ing been in the hands of Mr. H. T. Burr, now instructor in the 

 State Normal School, New Britain, Connecticut. A course in 

 Oceanography was given for the first time, by Dr. Daly, in the 

 spring of 1899, and repeated in 1900. By permission of Mr. 

 Agassiz he was given access to the " Blake," and other collec- 

 tions of marine sediments, for special study. 



The summer course in Physical Geography was given in 1899 

 by Dr. Daly and Mr. Twiss, and in 1900 by Professor Davis with 

 the assistance of Mr. H. T. Burr ; in each season it was attended 

 by about forty persons, mostly teachers. 



Professor Ward reports that the most important additions to 

 the laboratory materials for use in the courses in Meteorology 

 and Climatology were three large-scale colored charts, enlarged 

 Irom those prepared by Buchan and published in the volume 

 on "Atmospheric Circulation" of the "Challenger" Expedition. 

 Other additions were a large number of diagrams, enlarged for 

 class use from text-book figures ; a number of new mounted and 

 colored maps, illustrating the climates of the United States, for 

 use in Geology 25 ; a sling psych rometer and a black bulb ther- 

 mometer in vacuo. A collection of laboratory reference-books for 

 use in Geology 25 was begun, and promises to be a great help 

 to the students in that course. It is proposed to add to this col- 

 lection every year, and, as all these books are gifts from the 

 instructor, neither the Harvard College Library nor the labora- 

 tory have been put to any expense in the matter. During the 

 year the bound volumes of the Annalen der Hydrographie und 

 maritimen Meteorologie, which are frequently consulted by stu- 

 dents in courses of Meteorology, have been transferred from the 

 College Library to the Laboratory Library on deposit. All the 

 pilot charts of the North Atlantic and North Pacific Oceans, pub- 

 lished by the U. S. Hydrographic Office, which have considerable 

 use in the laboratory, were bound. The charts can thus be more 

 easily handled, and are less likely to be torn. 



In Professor Davis's absence during the year 1898-99, Profes- 

 sor Ward was appointed Chairman of the Department of Geology 

 and Geography.
