and photographic diagrams were added to those already in use for 

 teaching. Dr. Laurence LaForge donated a considerable collection 

 of fossils from the New York State Devonian, especially the 

 Chemung group. 



Professor Ward gave his usual courses in Meteorology (Geology 

 B and 1) and Climatology (Geology 19 and 25), and also a new 

 research course in Climatology (Geology 26). A portion of the 

 thesis prepared by Mr. W. S. Tower in the latter course has been 

 published in the " Bulletin of the American Geographical Society " 

 (Yol. XXXV. pp. 253-260). The purchase of thirty sling 

 psychrometers made it possible for the first time to give the class 

 in Elementary Meteorology some actual observational work with 

 these important instruments. The results of this innovation were 

 most satisfactory, and emphasized the need of introducing more 

 instrumental work in this course as soon as possible. Sixteen sets 

 of mounted weather maps of recent date have also added greatly 

 to the interest in the laboratory work in Geology B. Professor 

 Ward was occupied for some months with the proof of his 

 translation of Hann's "Handbuch der Klimatologie," which was 

 published in April, 1903. 



Professor J. B. Woodworth reports an increased number of stu- 

 dents in courses 5 and 8. There were added by purchase to the 

 equipment of the laboratory in Professor Woodworth's charge dur- 

 ing the year a collection of New York State rocks, representing 

 the various horizons of the Palaeozoic column there developed ; sev- 

 eral rocks and minerals to fill gaps in the study series ; a set of 

 wall maps of the continents, and, for field work, a small plane table 

 and alidade. Mr. I. Bowman was employed from time to time in 

 labelling the new cases and preparing trays for the reception of 

 the rock collections. Every case in this section of the new build- 

 ing is now in working order, and a catalogue is under way, 

 designed to facilitate reference to any desired object, including the 

 maps and specimens. Mr. Smith during the year completed 

 the numbering and cataloguing of the geological maps in Room 

 23, and materially advanced the same work upon the rock collec- 

 tions. A few gifts of interest have been received, notably a 

 collection of apparently sand-blasted pebbles from the Keweenaw 

 conglomerate of the Lake Superior District, from Mr. C. H. White. 



Professor J. B. Woodworth, under the auspices of the New York 

 State Museum, continued during the year, as time permitted, his 

 investigation of the pleistocene geology of the Hudson and Cham-
