water flows into the well from the pool for 35 seconds, when the 
same series of phenomena repeat themselves. Such are the facts. 
he explanation of the action may be readily imagined. Th 
pressure of the gas having relieved itself in throwing out of the 
w 
pressure of the gas becomes so great again that instead of rising 
until the pressu 
well till the pressure of the gas in its reservoir has increased to 
such an extent that it thrusts out of the hole the larger column of 
water to a height of trom 85 to 115 feet.

other column is produced by either of the gas veins exclusively, 
for the gas must be flowing from both horizons more or less all 
the time. It will be noticed that more water flows into the hole 
directly after the larger column has been thrown up, and that the 
smaller column throws up less water, and vice versa.
