manifest in swiiiii^'ing over large sections of 

 2-iiich mesh No. 13 wire-netting is ocular proof 

 of its value. Quite aside from this, however, 

 its highest value lies in the emancipation of 

 both monkey and visitor from the objection- 

 able prison bars, that for a century have stood 

 between them. 



CAGE SERVICE. 



The cleaning of mammal cages from the 

 front is not. and never can be, satisfactory. 

 The principle is bad, and its application is 

 worse. The chief obstacle in the way of cage 

 service wholly from the rear lies in the neces- 

 sity for direct communication, for the animals, 

 between the interior and exterior cages. 



Just how this difficulty has been met in the 

 planning of the Lion House will appear in a 

 future number of the Bulletin. In the Alonkey 

 House, a Keepers' Passage, 3 feet wide and 

 7 feet high from the floor of the building, 

 has been constructed between the interior 

 and exterior cages, with doors opening into 

 every cage of both series. Its flat top serves 

 partly as a floor for the interior sleeping- 

 boxes, and partly as a convenient and comfort- 

 able shelf for the inmates of the cages, upon 

 which they will show off to excellent advan- 

 tage. An open space between the sleeping- 

 boxes leads to the window, by which the mon- 

 key habitant passes at will from his interior 

 apartments to that in the open air. 



The Keepers' Passage is reached from both 

 ends, and also by two cross passages, which 

 lead directly from the floor of the main hall. 

 The latter afford quick and easy access from 

 the interior of the building to every cage, with- 

 out as well as within. Each service door of 

 the cages is provided with a peep-hole, in order 

 that the keeper may know the whereabouts of 

 his animals before entering. 



HE.VTING, LIGHTING, AND VENTILATION. 



Like the Reptile and Bird Houses, the Pri- 

 mates' House is heated by hot water, partly by 

 direct radiation, and partly by registers. The 



temijcrature is regulated automatically by 

 means of a system of thermostats, antl will be 

 maintained at 75 degrees l-"ahrenheit. 



The lighting of the building and cages has 

 been very successfully devcloiied, and it is be- 

 lieved will i)r()ve admirably a(lai)ted both to 

 the wants of the animals and the ])ublic. The 

 total area of roof-glass is really very great, anil 

 this, with the grand windows in the western 

 front of the building, makes the whole interior 

 as light as could possibly be desired. 



The ventilating system for the building and 

 cages has been thought out with special care. 

 A feature of prime importance is the arrange- 

 ment by which warm air issues from under- 

 neath the interior wall cages, is drawn into the 

 cages, and after warming them and becoming 

 vitiated, passes out at the top instead of being 

 thrown into the auditorium. This has been 

 devised for the express jnirpose of carrying 

 off all wild animal odors without their passage 

 through any portion of the space occupied by 

 visitors. 



PLANS .\ND ARCHITECTURE. 



The ground plan and cage arrangements of 

 the Primates' House were designed in i8g6 by 

 the Director of the Zoological Park. The 

 architectural Vvork is by Messrs. Hcins & La 

 Farge, and the engineering by Mr. H. de B. 

 Parsons. The decorative animal sculptures 

 are from models executed by A. P. Proctor. 

 The terra cotta which forms so prominent a 

 feature of the building's adornment was manu- 

 factured by the Atlantic Terra Cotta Company. 

 The contract for the building was let by Hon. 

 .\ugust Moebus. Park Commissioner for the 

 Borough of the Bronx, and the work has pro- 

 ceeded under the joint supervision of the 

 Architects and Mr. Martin .Schenck, Chief En- 

 gineer of the Park Department for Bronx 

 Thorough. It is being erected by Thomas 

 Cockerill & Son, who are prosecuting the work 

 in a manner highly satisfactory to the Zoo- 

 logical Society and the Park Department. 

 Work began on February 10, 1901, and has 

 progressed with rapidity and precision. On
