270 RECORD OF DEEP-WELL DRILLING FOR 1905. 
1550. Well near Henrietta, Clay County. 
[Well begun and completed in April, 1904. Authority, J. J. Myers, contractor. No samples.] 
This well, according to the contractor, is a fair representative of the wells sunk in what is 
known as the Henrietta oil field. The sand, as the log shows, is near surface and the wells 
are mostly small producers. The rocks probably should be included in the Pennsylvanian 
series of the Carboniferous system. They are part of the "red beds."

I55."». Well near Trickham, Coleman County. 
[Well begun March i-l, 1905; drilling stopped in July, 1905. Authority, Milo M. Garvin, driller. No 
samples.] 
This deep well was drilled for oil. The rocks penetrated are part of the Pennsylvanian. 
(Coal Measures) series, which, in this pari of the Texas coal fields, has been divided by 
the Texas Survey into the Straw n. Canyon, and Cisco groups. The mouth of this well is 
apparently near the base of the Cisco group, so the rocks mentioned are nearly all in the 
Canyon group. The total thickness of the Coal Measures may be 4,000 i'od .
