The Second Cow Run Sand.—This is one of the least important mem- 
bers of the group now under consideration. It has been a small producer 
at Cow Run in Washington county for more than thirty years, but rarely 
has been found beyond that locality. It is reported, however, quite fre- 
quently, for the driller gives this name to almost any sand lying from 100 
to 500 feet below the first Cow Run sand, As may be seen from the 
records given the interval between the two is 400 feet. It lies 760 feet 
below the Pittsburg coal, and is the thickest member of the group, some- 
times exceeding 60 feet. Occasionally the formation is divided by a 
few feet of slate, in which case the oil lies in the lower part. The sand 
possesses no qualities that serve to distinguish it from the higher mem- 
bers. 
The sand belongs near the base of the Coal-measures. The partial 
record of the Rice well, given below, shows it to be the first sand above 
the Salt sand, the two being separated by 79 feet of shales, the latter 
probably the equivalent of the shales of the Logan group. This, with the 
thickness of the formation, and the fact that it is sometimes divided by a 
few feet of shales, makes quite certain its identification as the Massillon 
sandstone. 
The Macksburg 500-Foot Sand.—This is important at wince 
and vicinity only. It hes 670 feet below the Meigs Creek coal and about 
580 feet below the Pittsburg, as is shown in the NS et log of

This: sand commonly ranges from 10 to 30 feet in thickness. It is 
usually quite coarse, but does not become a conglomerate. Like the First 
Cow Run.sand, it does not form a continuous stratum, but is decidedly 
patchy. Stratigraphically considered, the formation belongs. near the top
