ington oil field in the vicinity of Linden and west of Gambles station. 
A number of these wells north of Linden occur in the syncline. Just^ 
outside of the borough of Washington the Morgan No. 11 well, drilled 
in 1900, has produced oil from this horizon. In North and South 
Franklin townships the sand has given a little oil in several wells. 
Some gas lias been produced from this horizon in the Zollarsville 
and Somerset fields. 
Bayard sand. — In the western and northwestern parts of the quad- 
rangle the wells arc in general not deep enough to reach the Bayard 
sand, and nothing is known of it. In Morris Township several wells 
pass into the Elizabeth without reporting the Bayard, and as few of 
the deep wells in the Rogersville quadrangle note this sand it may 
die out in that direction. It is reported in one well in North Frank- 
lin Township. In the Deemston field and vicinity a great many 
wells penetrate the Bayard, which is usually reported 50 to 150 feet 
below the top of the Fifth. Owing to its position it is frequently 
called the Sixth sand, hut this name has also been applied to the 
Elizabeth. In thickness it averages about 20 or 30 feet, here and 
there amounting to as much as 50 feet. 
The Bayard sand is reported in numerous wells in the Zollarsville 
field, where the distance below the Pittsburg coal varies from 2,337 
to 2,479 feet. In a well southeast of Munntown it is 2,400 feet, and 
in North Franklin Township 2,231 feet. 
A large part of the gas produced in the Zollarsville field comes from 
the Bayard sand. In other sections the sand is not important, 
although beneath a Large proportion of the quadrangle it has never 
yet been penetrated. 
Elizabeth sand. The deepest sand which has yet proved of on4 
importance is the Elizabeth, which lies 50 to 150 feet below the top 
of the Bayard. It is also sometimes known as the Sixth sand, thougfl 
this nana' is more often applied to the Bayard. In general the Eliza- 
beth is supposed to be more persistent than the Bayard, being re- 
ported in nearly every well which reaches its horizon. It is, however,- 
one of the thinnest of 1 he sands, rarely exceeding 20 feet, and usually 
considerably less. In the Wavnesburg quadrangle to the south it is 
not known to exceed 7 feet. 
Notwithstanding its great depth, this sand has been penetrated 
by many wells in the Zollarsville field, where its distance below the 
coal ranges from 2,470 to 2,530 feet. By comparison with the meas- 
urements given for the Bayard sand it will be noticed that the Eliza- 
beth is much more constant. One measurement of 2,588 feet is 
reported, but this is an exception. The interval is 2,482 feet in a 
well north of Bentleyville, 2,506 at Lone Pine, and 2,400 in the 
Fonner field. 
In the Zollarsville field the interval from the Elizabeth to the top
