repaired, and repainted. On the first floor 218 were similarly treated. 

 On the second floor, in courtways, there were installed 58 new sills 

 with water bars bedded in cement, 27 new transoms, 25 new jambs 

 the full length of frames, and 33 new jambs of lengths varying from 

 one to five feet. One hundred and twenty large upper panes of glass 

 were reset in new putty. Ninety-six entire frames were scraped, 

 caulked and painted. 



On the roof a great amount of repair work was done, principally 

 where seams had sprung. In three places at the east end where ice 

 fell and punctured the rubberoid, allowing the insulation to get wet, 

 repairs and replacements were made. 



Among the tasks performed by the force under the supervision 

 of the Chief Engineer were the following: All lighting fixtures in 

 the exhibition halls were washed. Vacuum valves on all radiators 

 were cleaned and adjusted. Combustion control apparatus was 

 installed on the boilers, increasing the efficiency of the stokers. 

 Forty buckets were made for the coal conveyor. The boilers were 

 turbined and all brick work was repaired. The work of painting the 

 boiler walls and ceiling was begun (aluminum paint is being applied 

 to all iron work as a rust preventive). In the new Hall 12, devoted 

 to exhibition of sculptures of domestic animals, thirty-eight wall 

 lights and nineteen case lights were installed. To provide more 

 effective lighting of the systematic bird exhibits in Hall 21 the lights 

 were lowered five feet. In William V. Kelley Hall (Hall 17) seven 

 cases were equipped for concealed illumination of habitat groups 

 of animals, and fourteen label reflectors were installed. 



During the months when heat was required, the Museum con- 

 tinued, under its contract with the John G. Shedd Aquarium, to 

 furnish steam from its plant to the aquarium.
