Occasional thin beds of sandstone, with infrequent heavier beds and 
thin layers of limestone interstratified with sands and clays, also occur. 
In several of the wells many small fossils of Miocene age appear, usu- 
ally associated with a bed of grayish-blue sand. A number of the 
sand beds are water bearing, and might form a fairly good source of 
water supply for the Beaumont district, if properly exploited. Salt 
and sulphur water also accompany these sands at various levels, and 
in some of the wells have developed considerable flows. 
The upper 40 or 50 feet of these beds contain much decayed wood, 
and at an approximate depth of 45 feet the drillings indicate that 
when the land stood at that level it was subject to overflow by streams 
carrying great quantities of cypress and other timber. The only fos- 
sils found at this horizon were Rangia cuneata Gray and an undeter- 
mined oyster, from a depth of 45 feet, in the Ilarby well. These 
accumulations of buried vegetable matter continue downward to a 
depth of 800 feet in some of the wells. In the Island well Natica 
tuomeyi Whit, and Crassatella sp. were found at 800 feet. In the 
American Oil and Refining Company's well the drill passed through 8 
feet of bark and logs at 892 feet and again at 094 feet. In the Decker 
well logs of cypress occurred at a depth of 800 feet. These logs still 
possess the ordinary woody texture, while the bark retains its fibrous 
character and often by its toughness interferes seriously with the drill. 
In addition to this unaltered wood, more or less lignite occurs in the 
various wells, and small seeps or deposits of oil are found in nearly 
every well drilled throughout this area. 
Sands, clays, and even fair-sized bodies of sandstone and gravel 
make up the most of the strata encountered between 900 and 1,500 
feet. Below 1,500 feet the drilling is mostly through beds of blue, 
gray, and pink clays interstratified with limestones and sandstones 
down to the greatest depth yet reached. The limestones in these beds 
range in thickness from 2 inches to 2 feet. 
From the fossils found in the various wells in this region the geo- 
logic age of the beds appears to be approximately as follows 
1. Recent; to a depth of 45 feet. 
2. Pleistocene and Pliocene; between 45 feet and 800 feet. 
3. Miocene; between 800 feet and 2,200 feet. 
4. Eocene; below 2,200 feet. 
WELL RECORDS. 
The following well logs have been furnished, in all cases, by the 
owners of the wells or by the contractors with the owner's permission : 
Beginning at the northern end of the field, two wells have been 
drilled on the D. Easley survey near Pine Island Bayou, about 9 
miles north of Beaumont. These are known as the Sanger and Walker 
wells. Both are dry and have been abandoned. In drilling the Sanger
