ings were prepared for the group of eight exhibition cases that will 

 be required for the installation next year of the exhibit "Synopsis of 

 the Animal Kingdom" (see Department of Zoology, page 66). 



Bookcases, X-ray viewing-boxes, tray carts, and new fixtures 

 were prepared for various members of the staff of the Division of 

 Paleontology, and extensive changes were made in the office of the 

 Curator of Mammals to provide better conditions for study of 

 specimens. Two plant driers were built for the Department of 

 Botany. The postcard counters at the North Door of the Museum 

 were moved and additional counters installed to provide for the 

 increasing business of the Book Shop and sales of postcards. 



It was necessary again to winter-proof the steps at the north and 

 south entrances of the Museum by tuck-pointing with an elastic 

 waterproof compound. The old platform-scale was discarded and 

 the floor timbers were replaced with reinforced concrete. Fourteen 

 ventilating fans were installed in windows at the ends of the aisles 

 on the third floor for more comfortable working conditions for the 

 scientific staff. Throughout the building continuous cleaning and 

 painting proceeded according to schedule. In the boiler room the 

 summer season was used as usual to clean all boilers, pumps, and 

 motors in preparation for the next season's work. The breeching 

 and stack were cleaned of soot, the coal conveyor was overhauled, 

 and worn flights were replaced. New power circuits were run into 

 the pressroom to provide power for a new printing press and air- 

 compressor. New 48-inch fixtures were placed in several offices and 

 workrooms and twenty-four lamps were provided for various desks. 



The heating plant generated a total of 60,165,000 pounds of 

 steam, of which 10,998,470 pounds were sold to Shedd Aquarium 

 and 16,874,605 pounds were sold to the Chicago Park District under 

 existing contracts.
