NINETEENTH ANNUAL REPORT 103 



A complete grading plan of the surrounding grounds was 

 staked out on the ground, with final grades indicated, and this 

 grading is now being done by our own force of men. 



The great variety of carting of animals in cages, and the 

 variety of supplies and waste materials to be handled called for 

 a cart of special design. This was designed by our engineer, 

 and his plans executed in our own shops. 



Soundings were made and drawings and estimates were 

 prepared for a new concrete boat landing at the Boat House. 

 A massive door, to be operated from outside the building, was 

 designed for the handling of a dangerous elephant. A wire 

 screen was designed to separate the visitors from parrots on 

 perches, and many other smaller improvements, alterations and 

 repairs were planned. 



The Laboratory for the Curator of Birds was designed by 

 our engineer, and the drawings, specifications and contract were 

 prepared in his office, bids received, a contract was let, and per- 

 sonal supervision of the work was given by our engineer. Special 

 designs were prepared for the book cases and other cabinet 

 work, and these designs have been executed in our own shops, 

 in a very skillful and creditable manner. 



The large colored map of the westerly portion of the park, 

 made for exhibition purposes, has been gone over and brought 

 up to date, ready for any occasion which may call for it. 



A topographical survey of the easterly portion of the park, 

 embodying the newly added areas, showing the wooded portions, 

 the principal individual trees, exposed rock ledges, open glades 

 and abutting streets and properties, has been made and plotted 

 on the same large scale, (50 feet to an inch), as the map of the 

 westerly portion, which makes a map 54 inches by 10y 2 feet. 

 The whole will be colored so as to make the details conspicuous 

 from a considerable distance, and, in combination with the fin- 

 ished map of the westerly portion, will make a striking exhibit 

 of the natural beauties as well as the extensive improvements 

 which have been made during the years which the Zoological 

 Society has had these grounds in its charge.
