for the installation of exhibits. Such work included the construction, 

 painting, and installation of cases and lighting boxes and moving and 

 installation of large or cumbersome objects. Work was done in Halls 

 D, E, F, G, 8, and 9 of the Department of Anthropology and in 

 Halls 25 and 26 of the Department of Botany. Extensive remodel- 

 ing of cases for Hall 35 and rearrangement of exhibits in Hall 38 to 

 prepare for the improvement of the Brontosaurus exhibit were accom- 

 plished for the Department of Geology (see page 59) . The principal 

 work for the Department of Zoology was preparation of the cases for 

 "The Animal Kingdom" exhibit in Hall 13 and the case for the beau- 

 tiful "Colorful Birds" in the center of Hall 21 (see pages 62 and 73). 

 In addition, the Division of Maintenance built 200 trays for bird 

 storage, cut to size more than 1,000 pieces of cork for insect storage- 

 trays, installed steel track and hoist over the main storage tank in 

 the Division of Anatomy, and made miscellaneous changes in office 

 accommodations for scientific personnel. 



The usual summer cleaning and rehabilitation of the boilers and 

 brickwork were accomplished at the time of the summer shutdown. 

 Heater tank and chemical lines were washed out, chemical pumps 

 overhauled, and motors cleaned and repaired where necessary. The 

 top 50-foot section of the steel smokestack was replaced, the new 

 section was lined, and the stack was painted. New radiators were 

 installed in Hall 26 (Botany) in preparation for new-type transparen- 

 cies. All fire-fighting equipment was checked, repaired, and refilled 

 or replaced as conditions warranted. Under existing contracts, a 

 total of 27,157,000 pounds of steam was furnished to the Park Dis- 

 trict and Shedd Aquarium in addition to the heating requirements 

 of the Museum, which amounted to 35,079,300 pounds.
