 pints ), 14 feet below top of 3d S. S., and 48 hours afterward it was pro- 

 ducing at the rate of 10 barrels per day. 



The well declined very slowly, and on the 26th of June, 1873, it was 

 still producing 4 barrels per day.

But little salt water and no oil came into the well until the drill had 

 penetrated the 3d S. 8. about 14 feet, here both oil and salt water came in, 

 filling up the hole 75 feet or more. The best and softest part of the 3d S. 

 8. was from 21 to 28 feet below the top of the rock. 



Natural production less than one-half a barrel per day. 



Torpedoed February 26, 1873 (3 pints), 14 feet below top of 3d S. S. Pro- 

 duction brought up to 2 barrels of oil and 10 or 12 b*arrels of .salt water per 

 day. Pumped about four weeks at this rate, then commenced to increase 

 in oil and decrease in salt water, and in ten days was pumping 24 barrels 

 of oil per day. Pumped at this rate for ten or twelve days, then gradually 

 declined, and four months after torpedoing, was pumping 9 barrels daily.

 and some oil and salt water came in. Rock remained quite close until the 

 drill had gone down 13 feet in the sand when it l)ecame softer, but still 

 there was no perceptible increase of fluid in the hole. From 13 feet down 

 to 22 feet the sand was rather soft, and remained good down to 33 feet, 

 from which downward it gradually grew finer and harder.
