NOTES ON SOME WELLS IN PHILADELPHIA. 
South from Christian street, near the Delaware, there are many wells 
for sugar refineries, salt works, and ice factories. They penetrate the 
red, white, yellow, and other clays of the Potomac-Karitan clay series, 
to the basal gravels. Seven wells were bored for one sugar refinery at 
Morris and Otsego streets. The record from the memory of the well 
borer, according to Mr. Woolman, 1 is as follows: 
Feet. 
0-25 alluvium on fine yellow sand. 
25-65 mottled red and white clay. 
65-75 white potter's clay mixed with^gravel. 
75-90 fine sand of light-gray color. 
90-94 fine white clay, no gravel. 
94-109 white coarse sand. 
109-125 coarse white gravel, with pehhles and small cobhles, contain- 
ing water in large amount. 
One boring was made through to the rock at 140 feet. 
N. & G. Taylor's well, in the southeastern part of the city, is 12 
inches in diameter. Water found in heavy gravel at 130 feet was cased 
off. The first water obtained in the rock was at 400 feet, but the bor- 
ing was continued to 670 feet. The yield is 250 gallons a minute. The 
record is as follows: 2 
Feet. 
0-27 black muck (river alluvium). 
27-44 coarse gravel. 
44-45 yellow clay. 
45-75 red clay.
