Philadelphia Co., drilling near New Salem. 



Owners unknown, 8 or more wells. 



The W. & C. Co. have also seven wells (about 1400' deep), three miles 

 northwest of Latrobe, on a northeast and southwest line 2 miles long. 

 The northern three have a 6 inch pipe to Latrobe. The other four have a 

 10 inch pipe running east by Derry Station, P. R. R., to Laurel Hill, 

 where it feeds into the Grapeville-Johnstown main about ten miles from 

 Johnstown. The flowing pressure of the wells supplying Johnstown is 

 200 to 275 Ibs. per square inch. That of those supplying Latrobe, 90 Ibs. 



Trial wells east of this field have been unsuccessful, very little gas 

 being found. 



Salt water flowed from some of the Latrobe group of wells. 



The first and most northern well, the Fowler, was drilled in 1885, the 

 last and southernmost, Miller, No. 3, in 1887. Thdr volume of gas does 

 not equal that of the Grapeville wells, and requires a much longer time to 

 gauge up to the same normal of 500 Ibs. 



The proposition at first made to land owners, to pay $40 or $50 for a 50 

 Ib. well, and $1.00 extra for each additional pound, was not generally 

 accepted. 



Pressures along the main at every four miles (taken in 1836 and 1887) show 

 the loss of pressure by friction in a pipe of 10", increasing to 12", 16" and 

 20", thus : 



For first 20 miles 3250', ten inch pipe of f in. wrought iron. 



For next 12 miles, twelve inch pipe of inch " " 



For next 7| miles, sixteen inch pipe of T \ in. cast " 



For last If miles, twenty inch pipe of (?) ' " 



In the first column of the following table H. S. means High side. At 

 the 39th mile, the gauge is at "Reducer low side." 0. W. means the 

 Cambria Works at Johnstown.
