Rockery at the University of Pennsylvania, built in ISSl. By Eli K. Price. 

 {Rend before the American Philosophical Society, Dec. IG, ISSL) 



The form of the "White Oak leaf is used and the rocks so placed, that 

 every one may be seen. They are arranged according to the places where 

 they were found, to show how nature has disposed of them. 



Section I. — The large upright black stones at the three corners (a) came 

 from the tunnel on Thirtieth Street, near Master, 40 feet below the curb, 

 50 to 60 below the gravel hill. 



The quarried stones (&) are from the quarry of Price & Moore, next 

 westward of the "Woodlands Cemetery ; those next east (c) from the 

 quarry of Samuel C. Bunting, Junior, south of "Walnut, west of Forty- 

 fourth Street ; those farther east (cl) from William P. Supplee's quarry 

 east of Fifty-third Street, southAvard of Girard Avenue ; those marked (/) 

 from McKinley's quarry on Rittenhouse Street, near the "Wissahickon ; and 

 all the other quarried stones in this section (e and g) are from grounds of 

 Eli K. Price, on both sides of Twenty-ninth and Thirtieth Streets and of 

 Master and Jefferson Streets ; and the residu.e of this section is covered by 

 transported rubbed rocks from the gravel hills of the same and adjoining 

 grounds, at an elevation of about 100 feet. 



Section II is wholly covered by white and light-colored rocks, trans- 

 ported and polished, from grounds of George S. Harris, J. Clothier, 

 L. Dolby and others, on south side of Market Street, from Forty-eighth to 

 Forty -ninth Streets, a space of 480 feet by 246 feet, from a sand and gravel 

 hill of a height of about 100 feet above tide. The large white rocks at tlie 

 ends of this section lay near together, and show that when transported 

 they came as one rock. 



Section III. — Letter i are stones from the south side of Chestnut Street, 

 extending from Forty-seventh to Forty-eighth Streets, from a gravel and 

 sandy elevation of about 70 feet above tide, from the grounds of tlie 

 Byvam heirs and others. 



Section III. — Letter k are stones from both sides of Forty -fifth Street and 

 of Spruce Street, from grounds of Albert S. Letchworth and others. The 

 elevations were about 90 feet above tide. 



Section I"V is wholly covered by stones from the City Almshouse 

 grounds, westward of Thirty-seventh Street, and both sides of Spruce and 

 Thirty-eighth Streets, from gravel about 85 feet above tide.* 



* These elevations are based upon the following curb heights, which are about 

 ten feet lower than the gravel banks had been :
