30 ECONOMICAL GEOLOGY. 



The boring at^Strawn in the south eastern part of the county 

 failed to find a workable seam of coal, as shown by the follow- 

 ing copy of the record. The boring was made by Mr. Bennett 

 Eeeder : 



Total depth 302 



The boring at Saunemin in 1882 opposite the hotel, was not 

 carried deep enough to reach the workable coal, w r hich at that 

 point is 373 feet below the surface, while the boring was only 

 carried to the depth of 250 feet. There is probably but one 

 workable coal in the eastern portion of the county, which is 

 No. 2 of the general section. It is the equivalent of the lowest 

 seam in the shafts in LaSalle county, and is the one mainly 

 worked in Grundy county, and the southwestern portion of Will 

 and the northwestern township in Kankakee counties. 



A boring made at Forest since the foregoing pages were 

 written, the details of which were furnished by Carmon Bros., 

 found a coal seam, probably No. 2 of the general section, at a 

 depth of about 214 feet below the surface. The following details 

 were furnished by the parties above named:
