plain valleys. He has now in press a paper on the terminal sed- 

 entary impressions of the trails known as climactichnites found 

 near West Chazy, N. Y. As a result of last summer's field work 

 a pleistocene map of the Mooer's quadrangle in Clinton County, 

 N. Y., has been nearly completed. Mr. I. Bowman, temporary 

 assistant in the laboratory, left in April in order to take a position 

 on the United States Geological Survey. One full course and two 

 half-courses in Geology in Radcliffe College were conducted as 

 heretofore. One student from the Institute of Technology was 

 given a short course of verbal instruction in glacial geology. 



As Chairman of the Committee on the Gardner Collection 

 of Photographs, Professor J. B. Woodworth reports that, to 

 the zeal and efficient help of Mr. Smith, the collection of photo- 

 graphs and slides is at the end of this year for the first time in a 

 satisfactory condition as regards classification of the material, 

 and the registration of the data concerning it. The following 

 statement has been compiled by Mr. Smith for this report : —

The large number of views catalogued during the year repre- 

 sents an accumulation of some years concerning which informa- 

 tion was not obtained at the time when they were acquired. 

 The larger proportion of slides than photographs acquired during 

 the year expresses the present policy of the department concerning 

 purchases, since it has been found that the slides alone furnish 

 suitable material for illustration before the large classes. The 

 duplicates consist in the main of presentation copies, or of views 

 which have been intentionally duplicated. The negatives belong-

 and most of these are copied from photographs. On April 8 

 an exhibition of over 150 Norwegian photographs was made before 

 the American Academy of Arts and Sciences in the rooms of the
