A number of fine, sharp sands, resembling oil and gas sands, 

 were found, but all contained salt water, instead of the hydrocar- 

 bons sought. 



The figures in the column at the left of the accompanying well 

 section are the numbers of the consecutive strata from the top 

 downward ; those in the first column to the right show the thick- 

 ness of the strata, and those in the second column to the right give 

 the depth in hundreds of feet from the top downward. 



The well is located on lot No. 50 Congress street, in the city of 

 Emporia, at a surface elevation of 1130 feet above sea-level. 



Samples of the drillings were taken for the city by William 

 Campbell and placed in their regular order in glass tubes, which 

 are now on exhibition in the museum of the Kansas State Normal 

 School. 



Careful laboratory tests of the samples were made to see that 

 they were properly named, and from the results I am convinced 

 that the apparant discrepancies in the logs of wells from the same 

 locality are largely due to the inaccurate naming of the samples, 

 as well as lack of care on the part of the drillers to observe and re- 

 port changes that occur in the formation. 



On comparison with the samples taken from the Madison well* 

 I find it quite easy to correlate a great many of them by their 

 lithological character. The two sections agree very closely down 

 to the bottom of the Tola limestone, where, instead of the ninety- 

 nine feet of shale found at Madison, we have but seventeen feet at 

 Emporia, which practically throws the Garnett, Tola and Erie or 

 Bronson limestones into- one great series of limestone beds extend- 

 ing from the Lawrence to the Pleasanton shales, a depth of 400 feet. 



The Cherokee shales have a thickness of 356 feet, and the pro- 

 portion of sand encountered is not greatly different from that in 

 the Madison well. 



Good samples of the Mississippian were secured which prove 

 that that formation retains its flinty character westward at least as 

 far as Emporia. 



A careful comparison of the reliable logs and the samples from 

 the various deep wells in Kansas would be an interesting study 

 that I doubt not would result in valuable information in regard to 

 the character, thickness and extent of the various formations, and 

 perhaps throw some additional light on the geological history of 

 our state.
