as two to three barrels were forced out. Mr. Si ■hull/, thinks that the tubing 

 during this time must have been entirely filled \\ ith oil to the exclusion of 

 gas. In this case the pressure of the gas must have been sufficient to raise 

 a column of oil one square inch in section and 2000 feel high. Of course, 

 such an enormous pressure c >uld only be temporary. The oil Bowed from 

 the tubing bul for a few moments, the gas then prohably became thoroughly 

 mixed up with the oil which from its low temperature quickly congealed 

 and effectually choked the pipe. Altera few hours the gas ceased to Bow 

 entirely from the well and also from the adjoining well, No. 1. The gas 

 commenced to How again with greater energy after 36 hours of inactivity, 

 from both wells, Nos. 1 and 2. 



In the early part of 1877, the pressure of the gas seemed to increase sud- 

 denly. About the middle of May, four months after, the gas from both 

 wells, Nos. 1 and 2, ceased to flow for the second time without any obstruc- 

 tion having been knowingly placed in its way. No gas was found to conic 

 from either w T ell till July 14th, when it commenced to flow again. Up to 

 the present time the amount of gas increases and diminishes at irregular 

 intervals. The gas from this well was used as fuel in drilling well, No. 3. 



The elevation of Wilcox Well, No. 2, is 1642 feet above Ocean on the 

 corrected datum of the P. & E. R. R. which makes Wilcox Station 1527.*
