The company own 11 wells, five of which are unproductive 

 There is a market for a much larger supply, but the results of 

 the present experiment do not seem to justify an extension. 

 The attempt to reach Trenton rock is under consideration. 



Wherever gas has been found in the Medina, in this vicinity, 

 it comes from the " white sand," about 100 feet below the top of 

 the Medina,, or a little lower. The layers above this are charac- 

 teristically, but not always, a strong red, furnishing superior 

 building stone. The " white sand " itself is successfully quarried 

 at Gasport, though in some other places (as Medina) it softens to 

 incoherency under the action of the sun and weather. The oil- 

 bearing rock presents no "marked characters ; it is a sandstone of 

 medium coarseness, not specially porous, but lacking the firmness 

 of quartzite. 



No complete records have been kept. The few data presented 

 are obtained from notes kept by Mr. Frank Westcott. The 

 depth at which the Niagara, Clinton and Medina were first 

 struck are points not hard to discriminate, owing to the marked 

 character of the changes. 



Well No. 2 is the property of the brothers Westcott. It is 

 described as going 1,540 feet to gas; giving 8,000 feet in 24 

 hours, which is 2,000 less than at the start, six or seven years ago. 



This well, in the southern part of the village, may be compared 

 with one driven three miles north of the village, on ground not 

 differing much in elevation : 



To top of Niagara 

 To top of Medina 

 To gas

One of the northern wells (No. 4) is reported as passing 

 through 15 feet of salt at 565 feet. Other wells near this did 

 not strike salt. Salt water was encountered at various depths in 



most of the wells, in the Salina.
