226 ANNUAL REPORT 
wells have been drilled to the 500-foot sand, but this territory forms a part 
of the Macksburg field, and has already been considered in that connection. 
HARRISON COUNTY. 
This county has been extensively tested for oil and gas, but doubtless 
much work remains to be done. The oil already secured has contributed 
directly and indirectly much to the wealth of the community, and it is 
not unreasonable to expect that this will be an important source of revenue 
to the county during a considerable period in the future. 
The pools secured thus far (1903) are the following: 
i Cadiz: 5. Jewett ; 
2. Bricker; O, Scio? 
Be Sayer § 7. Bowerstown ; 
3. Maxwell; 8. Philadelphia Road; 
9g. Plumb Run. 
Geographically considered they may be classed in two groups, the 
last five named making one, and the first four the other. In this dis- 
cussion of the pools will be considered in this relation rather than in that of 
priority of discovery. 
The surface strata in this county lie almost entirely in the Conemaugh 
or Lower Barren and the Monongahela or Upper Productive Coal Meas- 
ures. Along the western side of the county the Upper Freeport or No. 7 
coal, which lies just below the Lower Barren Measures, is found a short 
distance above drainage, while in the southeastern corner of the county, 
the Pittsburg or No. 8 coal, which makes the base of the Upper Produc- 
tive Measure, is not far above drainage. 
THE CADIZ POOL. 
Discovery and Development.—In the summer of 1887 the Cadiz Oil 
and Gas Company drilled a well on the R. R. Cochran farm one mile north 
of the court house, the work having been done by Scott Watson of Brad- 
dock, Pa. His compensation was $1.25 per foot, but he was required to 
furnish casing, machinery, fuel, etc. When the Salt sand was reached a 
heavy flow of brine was liberated which ran from the top of the well, and 
the Berea sand, which was struck at a depth of 1,414 feet and was 50 feet 
thick, yielded neither oil nor gas. The company, however, was not de- 
moralized by this failure, but in the fall of the same year began drilling a 
well on the farm of W. D. Rogers in the southwest quarter of section 29, 
of Cadiz township. This well was located not because of any indications 
of the presence of the desired products, but to hold certain leases on large 
tracts which the company had in that vicinity. Work continued until the 
Berea sand was struck, but the little gas found did not warrant piping 
the well, and accordingly it was abandoned.
