Northwest of Spindletop the character of the beds underlying this 
portion of the field is well shown in the records of the Harby well on 
the Chaison tract, close to the Texas and New Orleans Railway line. 
This well has been drilled to a depth of 1,840 feet and the drill is still 
at work (June, 1902).
