feet respectively, but no advantage was gained by drilling the 

 last 200 feet. In the 1200 foot well, the last thing struck was 

 a very gritty rock, but underneath it limestone again appeared. 



There is no definite relation between the gas volume and the 

 rock pressure of a well. A well with low pressure may contri- 

 bute to the line steadily and well through a long period. Of the 

 daily production or capacity of the wells no record has been kept, 

 but the superintendent counts 100,000 cubic feet as the unob- 

 structed production of a good well for 24 hours. 



Gas is not found in definite horizons, but is mostly confined 

 to the Trenton limestone. It is likely to be found in small 

 amounts when the drill has sunk but five or ten feet into this 

 formation. From the surface downward till 600 feet of the 

 series have been traversed, there are innumerable accessions of 

 gas, the best of the flows being found in the lower part of the 

 formation. 



The dip of this stratum is strongest to the southward. On a 

 southwest line of six miles between Sandy Creek and Pulaski 

 the surface of the Trenton falls 150 feet, or 25 feet to the mile. 



In the last year the metered output showed the production of 

 the wells to be 17,280,000 cubic feet of gas. Probably enough 

 gas was used or lost outside of the meters to make the total 

 18,000,000 feet. 



The gas is sold at the nominal price of 35 cents a thousand, 

 but a discount of 10 cents is allowed for prompt payment of 

 bills, so that in reality the price is 25 cents a thousand cubic feet. 



The use of the gas is exclusively confined to house service. In 

 the severest weather there is occasionally a temporary shortage 

 in the morning hours, as the mains are but three inch pipes, but 

 on the whole the supply is eminently satisfactory to all the 

 patrons of the line. For the last three years the service has 

 been nearly perfect. 



In the location of the wells the aim has been to keep them 

 approximately one half mile apart, but no theory whatever has 

 affected the location and no " lines " or " belts " have been de- 

 veloped by the experience of the company thus far. In this 

 respect, as in all others, the gas conforms exactly to the char- 

 acters of shale gas.
