regarding underground conditions. Lee Hager's report of July 7, 

 1908, on the Blue Lake oil field, states that some three wells had 

 been drilled in the vicinity of Blue Lake up to that time. 



The Oakwoods Oil Company is said to have drilled a well to a 

 depth of 800 feet on the J. Strickland tract. A show of oil was 

 reported. Two wells were drilled by the Gum Springs Oil Com- 

 pany, the first reaching a depth of some 1,220 feet and the second 

 a depth of some 600 feet. All of these wells were drilled before 

 1908 and all of them were drilled in the vicinity of Blue Lake and 

 West Point Mountain. None of them report salt. 



At a later date at least two wells were drilled on the southwest 

 side of the dome, one just north of Llewellyn Gin and the other just 

 west of it. No detailed information regarding these wells was 

 obtained. According to local report, the well north of the Gin, 

 where casing still protrudes from the ground, was drilled to a depth 

 of 700 feet and was drilling in rock salt when abandoned. The 

 salt is said to have been struck at a depth of 300 feet. 



The only log of any of these wells which is available to the 

 writer is that of No. i well of the Gum Springs Oil Company, the 

 deepest of the reported wells. According to Hager, this well was 

 drilled on the east side of the "saline," a name which he gives to 

 the wide valley just south of West Point Mountain. This well 

 was evidently down on the flank of the dome. The log is quoted 

 after Hager's report as follows:
