WABASH AND EDWARDS COUNTIES. 53 



The following is a section of tbe bluff at this point : 



Ft. 



Loess and drift clays 30 



Sofr, shaly, micaceous sandstone 13 



Massive sandstone, partly concretionary 20 



Bine clay shale — partial exposure of 3 to 6 



Springs of water issue from the base of this sandstone, indicating the 

 impervious character of the underlaying beds, even where there is no 

 outcrop of the shales. Locally the concretionary sandstone contains 

 geodes of oxyd of iron, filled with a greenish or buff colored clay. The 

 base of the above section is some fifteen or twenty feet above the low 

 water level of the river, and the intervening beds which are probably 

 shales are not exposed. A boring was made here for coal under the 

 direction of Mr. J. Zevdiekjian, to whom I am indebted for the follow- 

 ing section of the beds passed through, and as the work was done with 

 a hollow drill and prosecuted very carefully, the section is probably a 

 very correct one. The bore was commenced just above the low water 

 level of the river, and something like fifteen feet below the base of the 

 foregoing section, and passed through the following beds:

This boring was commenced near the horizon of No. 11 coal, and 

 the beds passed through probably extend very nearly to No. 7. The
