JEFFERSON COUNTY. 793 
carrying off the most perfectly macerated vegetable matter from our 
modern swamps. In the general discussion of the formation of coal con- 
_ tained in Chapter XX X1, p. 125, the origin of cannel is so fully treated 
that no further reference to it is required here. 
From Brown’s Station to the mouth of Wills Creek there are no ex- 
posures which can serve to maintain the geological connection, and no 
explorations have been made by boring or otherwise that can help us in 
the correlation of the Steubenville coals, and those of Island Creek, and 
the upper river. This blank is greatly to be regretted, as, until it shall 
be filled, it will be perhaps impossible to definitely settle the mooted 
question of the proper numbering of the Steubenville “ Shaft Coal.” 
WILLS CREEK. 
The valley of Wills Creek lies altogether in the Lower Barren Meas- 
ures. At its mouth the base of this series is reached, and the tributaries 
of the stream have their sources in hills which rise above the Pittsburgh 
Coal. 
The following section gives the succession of the strata from the house 
of Deacon Robertson—-situated on the hills which overlook the valley 
of Wills Creek on the north side—to the mouth of the creek. From this 
level it is continued downward from the register of the well bored by Mr. 
J. McElroy, half a mile from the Cleveland & Pittsburgh Railroad, and 
commencing about twenty-five feet above it.
