000 cubic feet in twenty four hours. A well producing about 

 1,000,000 cubic feet is considered a good well. 



Some of the original wells in the Trenton field in Ohio 

 gave large outputs when first opened. In the vicinity of 

 Findlay and Bairdstown several very large wells were devel- 

 oped during the early history of the field, when the original 

 rock pressure was about 450 pounds to the square inch, and 

 several wells near the location named produced from 5,000,000 

 to 17,000,000 cubic feet in twenty four hours. Now there is 

 an average of less than 20 pounds of pressure. 



The more recently developed field in Knox county near 

 Mt. Vernon, Ohio, contains a number of wells with an output of 

 from 5,000,000 to 9,000,000 cubic feet in twenty four hours, 

 the original rock pressure being about 680 pounds to the square 

 inch. The gas in this field is found in the Clinton limestone, at 

 a depth of about 1,850 feet. 



Nearly all the natural gas produced in Indiana comes from 

 the Trenton limestone. The wells at first were generally large 

 producers, the output ranging from 1,000,000 to 10,000,000 

 cubic feet in twenty four hours. The original rock pressure 

 was 325 pounds to the square inch; it is now less than 70 

 pounds, and even this light pressure is being rapidly diminished. 

 There are localities where the original pressure is exhausted. 



In West Virginia there are a number of powerful gas wells, 

 the productive sands of which are deeply buried. The Big 

 Moses well, on Indian creek, Tyler county, was in its day one of 

 the very largest wells known, and for a few years delivered 

 immense quantities of gas. The estimated output of this well 

 when first opened was 35,000,000 cubic feet per day. Its life 

 was only about tw^o years, the nearness of petroleum deposits, 

 which were soon after developed, allowing the escape of gas, 

 and a great decline in pressure soon followed. There are nu- 

 merous deep wells in West Virginia that have a rock pressure 

 of over 1,000 pounds to the square inch; in some instances 

 1,500 poimds is recorded. A number of deposits of natural gas 

 have been found in three or more distinct sands or horizons; 

 the deepest wells measure about 3,200 feet. During the year 

 1900 a very large natural gas well was drilled near Goodhope, 

 in the southern part of Harrison county. This originally had
