Commenting on this record Professor White says: “The sand at 
1,116 feet 1s the one which was always known as the ‘Salt sand’ by the 
Macksburg operators, but its upper half only belongs in the West Virginia 
operators ‘Salt sand,’ while its lower half is the Big Injun, the Mountain 
limestone usually separating them, having thinned away and permitted 
the two distinct formations to combine practically into one rock. 
“Whether the sand at 685 feet or that at 775 represents the ‘Second 
Cow Run is not known certainly, but more probably the latter.” 
If Professor White is correct in the opinion expressed in the last par- 
agraph, the 500-foot sand and the Second Cow Run are not equivalent, 
but the latter lies go feet below the former. It will be noted that he regards 
the 800-foot sand as more probably the equivalent of the Second Cow Run. 
The interval between the First and Second Cow Run sands at Cow Run, 
where the deeper sand was named, is 400 feet. That at Macksburg, be- 
tween the 140-foot or First Cow Run and the 500-foot sands is but little 
more than 300 feet, while that between the 140-foot and the 800-foot sands 
is almost 400 feet. These relations support Professor White’s claims. 
The Macksburg oil field is located on an anticline. On one side the 
strata dip rapidly westward, and the Meigs Creek coal seam, which at the 
village of Macksburg lies 200 feet above the valley, is found at water level 
along the Muskingum where it has long been mined. The point at which 
the coal reaches its highest altitude has not been determined, but it must be 
near Macksburg. To the east the dip is apparently smaller than to the 
west, so that for a distance of ten miles in Salem and Liberty townships 
the coal is well above drainage, and is mined for local consumption. In 
fact the limestone or Pittsburg coal which lies about 80 feet below the 
Meigs Creek is found at a number of points above drainage in Liberty 
township, and as far east as Flint’s Mills, Ludlow township. 
The Oil Sands. —Few oil fields have the number of producing sands 
that this one has. However, the greater number of them have been of little
