OIL FIELDS OF TEXAS-LOUISIANA COASTAL PLAIN [bull. 213. 
The well is about midway between the Harby well and the Jones 
Development Company's producing well on lot 44 of Gladys City, and 
the producing well of the Denver-Beaumont Company on lot No. 5 of 
Spindletop Heights. The Denver well flows at 1,108 feet. Comparison 
and correlation of these well records should afford a fair knowledge 
of the structure of that portion of the plain lying to the northwest of 
the producing field at Spindletop.
