The twolargest pools are the Clarendon, in Warren County, which covers * The territories of which the areas are given here were defined by arbitrary lines,drawn to include all the surface where producing wells have been obtained or whichwas known, from actual drilling up to January, 1885, to be underlaid with oil. Allthe individual pools are shown on the accompanying map; the areas of some ofthem have been slightly exaggerated in order that they might be observed on ascale of twenty-five miles to one inch. A map on a scale of six miles to one inch,showing, with approximate exactness the areas of the pools, will appear in theannual report for 1885 of the Second Geological Survey of Pennsylvania. The totalarea of all the productive oil-territory in Pennsylvania prior to 1885 was 369 squaremiles. THE OIL-REGIONS OF PENNSYLVANIA AND NEW YORK. 421

The oil in this district comes from sands of varying geologicalhorizons, having somewhat the general appearance of the Bradfordand Allegany sand, but frequently coarser-grained and sometimescontaining small pebbles, which latter I have never known to havebeen found in the sands of the other two districts. According toMr. Carll, the depths of the Warren district oil-sands below theOlean conglomerate are as follows: North Warren sand, 1100 feet;Warren third sand, 1300 feet; Clarendon third sand, 1450feet; Cherry Grove third sand, 1625 feet; and Cooper (ForestCounty) third sand, 1850 feet. The Cooper sand is supposed tooccupy the same geological horizon as the Bradford and Alleganysand. The Allegany, Bradford, and Warren district sands I believeto be of Chemung (Devonian) age.
