and 4 of section) are used as a mixture in the manufacture of sewer pipe. 
The principal supply of clay comes, however, from below Coal No. 3. 
Dr. Garlick has an extensive terra cotta and drain-pipe factory, for 
which the raw material is obtained from the fire-clay of the “Clay 
seam,” and he has now the largest stock of such things as he manufac- 
tures to be found on the river. The principal articles made here are 
drain-pipe of all sizes from two inches to thirty-three inches in diameter, 
terra cotta chimney tops, vases, etc. 
The upper coal (No. 7) is clean and bright, mines in blocks, av is of 
better quality than the seam next below it. It is now not much used, 
as it costs more than the other. Coal No. 5 is very black and smutty, 
contains considerable sulphur, and has some “bony” coal in the lower 
bench. It costs two cents per bushel delivered at the works. The coal 
found beneath the ‘Roger seam,” at Freeman’s, has not been detected 
here. Its position is, however, indicated by a line of springs. Coal No. 4 
has been opened, but, being only eighteen inches thick, is not worked. 
The coal taken from this seam is very hard, and burns well, but leaves a 
red and rather copious ash. Coal No.3 has its usual sulphurous character, 
and is not mined. Analyses of the coals and clays of Elliotsville will be 
found in the tables given at the end of this chapter. 
At the Excelsior Works, Coal No. 3 lies just above the railroad; at 
Garlick & Sizer’s, seven hundred and twenty-eight feet south, it is from 
seven to ten feet below—showing a southerly dip of about one foot in a 
hundred. 
CROXON’S RUN. 
At Croxon’s Run are extensive factories which formerly produced fire- 
brick of good quality, but they are not now in operation. The following 
is a section of strata found in the hills here:
