Mr. R. L. Agassiz gave a first-class petrographic microscope 

 for use in research on problems in economic geology. In the same 

 generous spirit, Mr. Leighton deposited another microscope. 

 With the loan of other instruments from the Department of 

 Mineralogy and Petrography, a more temporary meeting of 

 Professor Graton's need of equipment in microscopes was ar- 

 ranged. 



Mr. R. W. Sayles's highly appreciated annual gifts consist not 

 only of service without stipend but also of numerous gifts of 

 valuable material. 



Similarly Mr. Edward Wigglesworth gives his services without 

 remuneration as Curator of the Gardner Collection of Photo- 

 graphs, and as Assistant in Geology 8. His report on the Gardner 

 Collection is summarized as follows:

The more important additions to the collection are: (1) Pro- 

 fessor Daly's slides (nearly 300), from The International Boundary 

 Survey, Canadian Pacific Railway Line, Montana, Mexico, and 

 the Hawaiian Islands. (2) Various geographical slides, (approxi- 

 mately 100), obtained by Professor Atwood for use in his courses. 

 (3) 250 palaeontological slides for Professor Raymond's work in 

 Geology 5. (4) 50 meteorological slides. The petroleum and 

 Scottish slides mentioned in last year's report are now catalogued 

 and entered in the above table. A set of 97 slides, the gift of the 

 Australian Commonwealth, has recently been received but has 

 not yet been catalogued. 



A Committee of the Division of Geology made a thorough 

 revision and improvement of the Divisional pamphlet. In the 

 course of this work, it was decided to rename all the geographical 

 courses, in the interests of a more systematic and telling statement 

 of the Departmental offerings. 



Prof. J. B. Woodworth conducted the following courses at
