The gravel, of course, is detritus brought down by the stream. The 

 interval represented by it is partly filled by exposures up the stream, as 

 follows :

Leaving twenty feet, not seen, necessary to make th-e section in the oil 

 well complete. There is no reason to doubt that Nos. 2, 3, 4, and 5 of this 

 section, as well as No. 2 of the oil well section, belong to the Waverly 

 series, which, therefore, includes all down to No. 8, the Huron shales. 



The Carboniferous conglomerate is here quite coarse, and contains 

 many pebbles two-thirds of an inch in diameter. The sandstone. No. 4 

 of the second section, is fine-grained, without pebbles, and works nicely 

 under the chisel. No. 5 is scarcely inferior to it. 



At the depth of 671 feet salt water was found in large quantity, and is 

 said by Mr. Doane to average nine or ten per cent, of salt. Under such 

 circumstances there can be no doubt that were there suitable means of 

 transportation the manufacture could be carried on here to profit. 



Licking Township. — Coal No. 2 has been worked by Mr. L. Stump near 

 Nashport, and is said to be somewhat more than two feet thick, and to 

 yield a coal of fair quality. Coal No. 1 undoubtedly exists west from Nash- 

 port, but is probably very thin, as no openings, or even exposures, were 

 observed. The outcrop of Coal No. 4 was seen at several localities, but 

 it is very thin. Near the Muskingum line the flint ore bed has been 

 worked by stripping. Coal is not mined to any extent here, as it can be 

 brought more cheaply by canal from Coshocton county. 



In the western portion of the township the Conglomerate and the 

 Waverly series are exposed. 



Cass Township. — About one mile west from Dresden a number of deserted 

 openings upon Coal No. 6 mark its western outcrop. On the road from 

 these banks to Dresden the following section was obtained :
