found at a depth of 504 feet, but no other indication of oil to the 
depth thus far reached. 
The J. M. Guffey Petroleum Company is drilling four wells on High 
Island, and the Bolivar and High Island Oil Company has a derrick 
erected, but has as yet (June, 1902) done no drilling. 
GEOLOGIC STRUCTURE. 
Too little is known regarding the stratigraphy and structure of 
High Island to make definite statements. It is probable that the first 
20 to 30 feet of yellow clay should be correlated with the Beaumont 
clays, which division may also include a portion of the underlying 
sands and clays. Below these beds are sands and gravels to a depth 
of somewhat over 100 feet, which may be the equivalents of the 
Columbia and Lafayette. These gravels are followed by sands, clays, 
and salt in the southwestern portion of the island, and by clays with 
limestone and gypsum in the northeastern portion. 
That the underground structure of the island is anticlinal, or dome- 
shaped, may be safely inferred from analogy with other districts in 
the coastal region. The data at present available are not, however, 
sufficient to determine the extent of the dome or the direction of 
its axes. 
KISER HILL DISTRICT. 
This district is located immediately west of the Brazos River, near 
the town of Columbia, and about 12 miles southeast of Damon Mound. 
Kiser Hill has an elevation of from 25 to 30 feet above the level of 
the river at Columbia, and from GO to 65 feet above sea level. The 
surface is underlain by brown sand or sandy loam, probably for the 
most part river alluvium. The surface of the hill differs slightly 
from that of the surrounding region, containing much more clay. 
The limits of this district are not yet determined, since only a single 
well has been drilled. This is the Equitable Mining Company's well, 
which has reached a depth of only 600 feet. At a depth of 360 feet 
a small quantity of petroleum was obtained from a bed of sand. At 
600 feet a strong flow of gas was encountered, with sufficient pressure 
to blow out the drilling tools from the well. Great quantities of 
water and sand, with a small amount of petroleum, were brought out 
by the gas. The flow of gas was controlled after much difficulty and 
cased off. It is the intention to drill this well deeper, and the pros- 
pects appear to be favorable for obtaining oil in commercial quanti- 
ties. 
MINOR TEXAS DISTRICTS. 
At several other localities in the Gulf Coastal Plain of Texas pros- 
pecting for oil has been carried on to some extent. In some cases the 
location of the wells was determined by certain supposed surface
