20 A GEOLOGICAL HISTORY. 



North River, and ended at Mr. Lispenard's place, 

 near where Canal or Laight Street now is. The 

 sand, gravel, and other material of these hills, 

 were not so coarse and so varied as those to be 

 described. 



In the same line, after passing Lispenard's creek,* 

 we come to what was called Richmond Hill, (or 

 rather, as the boys 50 years ago called it, " The 

 General's Woods,") which was 30 feet higher than 

 the present level of " Tivoli Garden."f The ma- 

 terials of this hill were the coarsest of all the hills 

 on the North River ridge, but the boulders were 

 not so large as those at Corker's Hook. 



A high hill was dug down between where An- 

 thony and Canal Streets now cross Broadway. In 

 this hill were all the varieties of this formation ; its 

 height was from 25 to 30 feet above the present level. 

 On this hill, near where Franklin Street now is, 

 on the east side of Broadway, stood a water basin, 

 built before the Revolution, for supplying the city 

 with water. A large well was dug near where 

 White Street now crosses Elm Street ; this well 



* This creek commenced at the Collect pond and ran through Lispe- 

 nard's meadows to the North River. 



t This house stands within a few feet of the spot where it stood 50 

 years ago, but has been lowered to its present level; around this old 

 mansion stood oaks, chestnuts, and other aboriginal trees of gigantic size. 

 I remember one old chestnut tree which was at least 7 feet in diameter.
