The most valuable accession of recent years is a set of 430 

 lantern slides of the French Alps and the Pyrenees, the gift of 

 Professor Raoul Blanchard. Professor McAdie presented a 

 small set of slides of exceptional merit, illustrating frost forma- 

 tion. The slides given by the Australian Commonwealth men- 

 tioned in the last report have been catalogued. 



Owing to other duties, Mr. Wigglesworth resigned the curator- 

 ship of the Gardner Collection. The Department heartily regrets 

 this and records its gratitude for his unselfish devotion. 



Professor Woodworth gave the Harvard courses, Geology 

 5, 12, 19, and 20e and the Radcliffe courses, Geology 4 and 5. 

 Owing to his work on the geology of Cape Cod and the islands 

 along the Massachusetts coast for the U. S. G. S., he was not able to 

 maintain the monthly issues of the seismographic records; during 

 the latter half of the year 1916, the records of the Harvard station 

 were kindly deciphered and published by the U. S. Weather 

 Bureau. Room 55 in the Geological Section of the Museum 

 has been fitted up for laboratory work in Professor Woodworth 's 

 advanced courses. As a member of the committee on geology 

 and palaeontology of the National Research Council and as 

 chairman of the subcommittee on the use of seismographs in war, 

 Professor Woodworth devoted much time to those services. 



Professor Atwood conducted the geographical courses numbered 

 1, 6, 7, and 20a. In cooperation with Mr. Peattie he prepared 

 papers entitled "Saving the silts of the Mississippi" and the 

 " Relation of landslide and glacial deposits to reservoir sites in the 

 San Juan Mountains". He continued his work on the more 

 comprehensive report, covering the physiography of the San 

 Juan Mountains, Colorado.
