The lower Coal Measure limestones often carry ores. In the bed of 

 Monday Creek, near Henry Hazleton's, below Shawnee, ore and flint are 

 found in the horizon of one of the lower limestones. The former place 

 of exposure of this ore is now concealed by the fine coal and debris 

 brought by the stream from the Shawnee mines above, but it is seen on . 

 the land of Mr. Moore a little below. The ore is in three benches or 

 layers, the lower one being very flinty. There are altogether about fif- 

 teen inches of ore. Analyses of samples of these ores were made by 

 Prof. Wormley, with the following results:

On the land of Mr. Moore is the same ore from six to eight inches 

 thick, resting upon blue shale of six inches ; below which is a fossilifer- 

 ous limestone of eight inches, and underneath all a thin coal. This 

 group is by Locke's level one hundred and fifty-five feet below the Nelson-
