From this point a boring was made to the depth of 38 feet, pass- 

 ing through the following strata :

Gray limestone (Lower Carboniferous). 



The gray limestone at the bottom of this boring is probably the 

 upper division of the Lower Carboniferous series, and no coal would 

 be found by sinking to a greater depth. Nos. 19, 20 and 21 of the 

 shaft probably represent coal No. 1, while No. 15 represents a local 

 seam. No. 9 is coal No. 2, No. 5 is coal No. 3, and No. 3 of the 

 shaft is either a local development or a representative of coal No. 4 



No. 18 is said to be an excellent quality of tile clay, and the shaft 

 may be utilized in the production of this useful article for the man- 

 ufacture of pottery and drain tile on a large scale. 



A boring made at Milford, in Iroquois county, was carried to the 

 bottom of the Coal Measures, reaching the Lower Carboniferous 

 limestone at about 200 feet, and though two coal seams were passed 

 through neither of them were thick enough to be of any practical 

 value. The following beds were passed through in this boring:
