No. 2. Old road to Carlisle. The same result is obtained along this 
line. At about two miles from New Bloomfield is a small roadside cut- 
ting showing Chemung shale and at about one hundred yards further on 
is an indistinct but manifest Oriskany ridge. Between the twois a narrow 
strip of Lower Helderberg limestone. 
No. 3. West road to Gibson’s rock. At about two miles anda half from 
New Bloomfield, the lower Portage bed (Cardiola shale) dipping at 
nearly 90° crops out on the roadside, and within one hundred yards the 
road passes over the Oriskany sandstone (near Mr. 8. Brown’s). 
No. 4. Road to Montebello narrows. This road, running almost due 
east, passes over a great distance of Chemung shales rising to a higher 
horizon than along either of the roads already mentioned. But on turning 
to the south at the entrance to the narrows two cuttings, only one hundred 
and fifty yards apart, show the Chemung shales and the lower Helderberg 
limestone. 
No. 5. Road from Perry Furnace to Gibson’s rock. The old Perry 
Furnace lies upon the lower Helderberg limestone. The Oriskany sand- 
Stone does not make any conspicuous ridge along this road. But at a few 
hundred teet south of the Furnace the base of the Hamilton sandstone is 
seen and passing through the narrows its upper limit may be easily de- 
tected, Following this at a distance of about four hundred feet comes in 
the Oriskany sandstone, forming a distinct ridge of rocks. he fault there- 
fore comes through in this interval, bringing the Lower Helderberg lime- 
stone in contact with the Hamilton Upper shale. The throw here is less 
than farther east, not exceeding 1650 feet measured at right angles to the 
beds, or 2300 feet if measured vertically. 
No. 6. Road to Losh’s run (Polecat road and Ohio Wharf road), This 
road strikes the line of fault about six miles east from New Bloomfield. 
The exposures are not quite so striking as in the places already mentioned, 
but the fault is equally conspicuous. Chemung shales occupy the ground 
south trom Mahanoy ridge to Dick’s hill with, so far as can be determined, 
a tolerably uniform dip of about 40°. Immediately at the northern foot of 
Dick’s hill the lower Helderberg limestone is quarried. Though no cut- 
ting showing the shales can be seen close to the quarry, yet the surface of 
the fields shows the presence of the Chemung sandstone, and, from the 
color, it is apparently nearer the top than the bottom of the group. Some 
indications also are present, which seem to show that the yellow shales and 
brown sandstones of the beds underlying the limestone, are brought up into 
contact with the Chemung. The throw of the fault here is consequently 
greater than at any one of its western exposures, amounting, if measured 
square across the beds, to about 4650 feet, or vertically 6510 feet. 
Westward of the lines hitherto followed the fault may be traced. It 
cuts off the Hamilton sandstone of South Furnace ridge, which declines in 
consequence to the general level of the country. This extinction of the 
Hamilton Sandstone ridge takes place about two miles south-west of the
