of development until sufficient prospecting has been done to definitely deter- 

 mine the thickness and extent of a coal seam in any given locality. Where 

 a seam has a tendency to thin out rapidly in a locality — and this fact can gen- 

 erally be determined by an examination of the outcrop — there should be a 

 great number of the cheapest kind of prospect holes put down with the sole 

 object in view of testing the thickness of the seam in that particular locality. 



The Chaffin mine is about two miles southeast of this shaft. At this place 

 the seam outcrops in a small creek, immediately below a shaly limestone, and 

 is twenty inches thick. At various times in the past coal has been taken out 

 of this place for various purposes. The mining was done by following the 

 seam from the surface a few feet. No prospecting has been done to deter- 

 mine the extent of this thickness in the immediate vicinity. 



On John Kellett's farm, about three miles southwest of Waldrip, a drill 

 hole has been put down three hundred and twenty-four feet, near the bank 

 of the river. Out of this hole flows a stream of salt water which by analysis 

 gave thirty pounds of common salt to one hundred gallons, with a trace of 

 iron. With the water comes up a flow of gas sufficient to keep a constant 

 flame burning several feet high. No effort has been made to test the quan- 

 tity of gas in this locality.
