Salt water and gas appeared in 2d S. S. Third sand white and soft. Oil 

 and salt water came in at a point 12 feet below its top. The best quality of 

 sand was between 17 and 25 feet. Soft sand from 28 to 30 feet. Indica- 

 tions of a crevice between 38 and 40 feet. 



Natural production 2 barrels per daj'. 



Aug. 10th, 1872. Torpedoed (8 pints) at 18 feet below top of sand. Pro- 

 duction rose to 14 barrels per day, but declined in 10 days to 8 barrels. 

 Then sank to 6 barrels. Pumped steadily 6 barrels per day for a long time, 

 then slowly began to decline, and on the 26th of June, 1873, it was pump- 

 ing less than one barrel per day.

Considerable gas in 2d S. S. 



Softest part of 3d S. S. commenced at 3^ feet below its top, and continued 

 down to 7 feet. At this point there was a large amount of gas and the well 

 filled rapidly with fluid, the larger portion of it being salt water. From 

 14 to 18 feet below the top of the sand, the composition of the rock was 

 such as to warrant the expectation of a good well, but there was so much 

 fluid in the hole at this time that it could not be positively ascertained 

 whether oil came in at this point or not. 



Natural production 1^ barrels per day. 



Aug. 29th, 1872. Torpedoed (3 pints) at 5 feet below top of 3d sand. 

 Production first 24 hours thereafter, 12 barrels ; and ten days later, 10 bar- 

 rels per day. 



Nov. 18th, 1872. Exploded a torpedo shell filled with giant powder, said 

 to equal in strength a 3 pint nitro-glycerine torpedo. Before torpedoing 

 the well was pumping 5 barrels per day. Four days afterwards, it was 

 producing 6 barrels per day. The explosion filled up the well hole 10 feet. 

 [Meaning, no doubt, with the crushed and broken fragments of the sand 

 rock. ]
