Children lost in the Park, and property lost or found, should be 

 reported without delay at the Chief Clerk's office in this building. The 

 telephone call of the Zoological Park is Tremont 953. 



Wheeled Chairs. — By persons desiring them, wheeled chairs can 

 always be obtained at the entrances, by applying to gatekeepers, or at 

 the office of the Chief Clerk, in the Service Building. The cost is 25 

 cents per hour ; with an attendant, 50 cents per hour. 



Physical Aspect of the Grounds. — Roughly estimated, one-third 

 of the land area is covered by heavy forest, one-third by open forest, 

 and the remaining third consists of open meadows and glades. The 

 highest point of land in the Park is the crest of Rocking Stone Hill, the 

 elevation of which is 94.8 feet above sea level. 



Topography. — Speaking broadly, the Zoological Park is composed 

 of granite ridges running from north to south. In many places their 

 crests have been denuded of earth by the great glacier which once pushed 

 its edge as far south as New York City. In the valleys lying between 

 these glacier-scraped ridges, great quantities of sandy, micaceous soil 

 have been deposited; but in one spot — the Wild-Fowl Pond — what was 

 once a green, glacial lake fifteen feet deep, presently became a vast rock- 

 walled silo filled with vegetable matter and a trembling bog of peat. 

 Everywhere in the Park glacial boulders of rough granite or smoothly 

 rounded trap-rock, varying in size from a cobble-stone to the thirty-ton 

 Rocking Stone, have been dropped just where the warm southern sun 

 freed them from the ice. The Park contains thousands of them, many 

 of which have been removed from walks and building sites only with 

 great labor. 



The Rocking Stone, a colossal cube of pinkish granite, poised 

 on one of its angles on a smooth pedestal of rock, is the Zoological Park's 

 most interesting souvenir of the glacial epoch. Across the bare face of 

 the rocky hill in which lies the Crocodile Pool, there are several glacial 

 scratches pointing directly toward the famous boulder ; and who will 

 say it had no part in making one of them? 



The Rocking Stone stands on a smooth table of granite on the 

 southern shoulder of the hill overlooking the Buffalo Range. Its extreme 

 height is 7 feet 6 inches ; breadth, 10 feet 1 inch ; thickness, 8 feet 1 

 inch, and its weight, as roughly calculated, is 30 tons. A pressure of 

 about 50 lbs. exerted on the most northern angle of the stone causes 

 its apex to swing north and south about two inches. 



Streams and Ponds. — The Zoological Park contains about 34 acres 

 of still water, of which Bronx Lake comprises 25 acres, Lake Agassiz 

 5^4 acres, Cope Lake, the Wild-Fowl Pond, and Beaver Pond together, 

 about 3^2 acres. The two larger lakes are fed by the Bronx River,
