66 ECONOMICAL GEOLOGY. 



well was undertaken in the expectation of finding natural g-is 

 in which the company were measurably successful, and the 

 details of the record are given on a preceding page. The first 

 ilow of water, gas and oil was obtained soon after passing 

 through the Kinderhook shales and in strata that are probably 

 of Devonian age, but this was thought to be increased on pass- 

 ing through the Trenton limestone. The flow of water is esti- 

 mated at 800 barrels per day, but no successful attempt lias 

 been made to measure the pressure of the gas. The production 

 of oil is only about one-half gallon per day. 



A boring at Moumouth in Warren county failed to obtain a 

 flow of water, although carried down through the St. Peters 

 sandstone, which at that locality was reached at the depth of 

 1,078 feet. The following record of this boring was furnished 

 by Mr. J. H. Southwell of Rock Island. 



No. Feet. 



1. Drift clay 07 



2. Coal measure shale 5 



3. Burlington limestone % 



4. Kinderhook shale 121 



o. Devonian shale and limestone 109 



0. Niagara limestone 08 



7. Cincinnati shale 83 



8. Trenton limestone 52(i 



'J. St. Peters sandstone 151 



Total 1,232 



No indications of natural gas or oil were observed in this 

 well. 



A boring was made at Jacksonville a few years since in search 

 of coal, but as it commenced near the bottom of the coal meas- 

 ures, the prospect of a successful termination of the experiment 

 was far from encouraging to any one conversant with the 

 geology of Morgan county. This boring was carried to the 

 depth of about a thousand feet, and I am indebted to Prof. H. 

 E. Storrs for a copy of their record, which I have summarized 

 as follows: 



No. Feet. 



1. Drift clay, &c 15tt 



2. Coal measures, with one coal seam 100 



3. Lower carboniferous limestone 433
