ANNUAL. REPORT SMITHSONIAN INSTITUTION, 19 3 6 



work at the shops is finished. Terra cotta sewer, 1,700 linear feet of 

 12-incli diameter, was hiid from tlie District sevv^er along the creek to 

 the vicinity of the great flight cage in the ravine. This was a step 

 in the line of diverting all sanitary sewerage from the creek into the 

 District's sanitary sewers. Kepairs were also made to the storm 

 water sewers in the same ravine, and 2,000 feet of various sized water 

 lines were laid. 



The improvement of the grounds by planting grass, shrubs, and 

 trees, removal of objectionable or surplus vegetation, grading, and 

 related grounds work has been carried on with very satisfactory re- 

 sults. Material progress has been made in the removal of poison ivy. 



A small amount of miscellaneous repairs to buildings and fences 

 has been carried out with funds from our regular appropriation 

 and unskilled labor assigned to us under W. P. A. When certain 

 W. P. A. clerical employees assigned to the Zoo were not urgently 

 needed on routine work directly connected with the W. P. A., they 

 rendered substantial assistance in repairing a considerable number 

 of valuable pamphlets relating to zoology and in arranging them in 

 the Zoo library. Just at the close of the year a bookbinder assigned 

 to the Institution by the W. P. A. was detailed to this branch of 

 the Smithsonian library. This arrangement is most promising for 

 the binding and repairing of many valuable publications in our 

 excellent vertebrate zoology library which otherwise would rapidly 

 deteriorate.
