DESCRIPTION OF OIL POOLS. 
FIVE POINTS POOL. 
In the northern half of the quadrangle the synclinal basin rises 
west of Five Points. The oil has accumulated on the slope of this 
basin from the north, west, and southwest. The presence or absence 
of salt water in the center of the basin was not positively determined. 
If the water is absent, there seems to be no good reason why the oil 
should not extend to Raccoon Creek and southward to Bavington. 
It will be noted, however, that the surface structure shows the Five 
Points syncline as an independent basin. This structure has been 
largely eliminated on the convergence sheet. If lack of sufficient 
data on the convergence sheet has thrown the map of the Hundred- 
foot sand into error and the Five Points syncline is an independent 
basin on that sand, the same as on the Pittsburg coal, there is good 
reason why the production should not extend to Bavington. 
It is not known whether any wells have been drilled below the 
Hundred-foot sand in search of lower sands in the center of the Five 
Points basin, but if this has not already been done it seems advisable 
to do so, for if the lower sands are present in this locality they are 
probably productive. 
FLORENCE POOL. 
The oil pools southeast of Florence are accumulations upon struc¬ 
tural terraces. The conditions of accumulation in these pools are 
impossible to determine from the surface, owing to the lack of par¬ 
allelism between the outcropping strata and the oil-bearing sand. 
BURGETTSTOWN POOL. 
The oil pool which now extends from Cherry Valiev to the village 
of Cross Creek was in course of development during the progress of 
the field work on which this report is based. The development of 
this pool commenced in Cherry Valley and extended in a southwest¬ 
erly direction to the valley of Burgetts Fork. Here it seemed for a 
b} ^ hole (No. 572) on the farm of II. J. Lyle. 
As this limitation did not appear to agree with the geologic conditions 
as know n at that time, the writer then suspected that an accumula¬ 
tion of oil existed on the western side of the synclinal basin, as had 
been found on the eastern side. This territory has since proved to 
be productive. 
From structural conditions, there seems no reason why all of the 
aica lying south and east of the 1,090-foot contour, which goes 
through Cross Creek village and passes to the north and west of 
Quakers Knob and thence northeast and east to a point north of the
