White Lias Limestone. 43 



tural puposes. This portion of the deposit contains some fossil re- 

 mains. Figure 21, (page T of the wood cuts) was taken from this 

 bed, a little distance from this spot, and resembles the caudal half of a 

 fish. The drawing is much reduced. The original, when taken from 

 the rock, was three feet in length and about six inches in diameter, 

 but has been broken and shortened. The figures on the surface dif- 

 fer in their arrangement in this respect, from any other in ray pos- 

 session, the greater diameter of the scaly impression is placed 

 transversely, while in the others it is longitudinary. — 100 feet. 



9. Yellowish, argillaceous soil, rich and loamy ; covered with a 

 growth of yellow and white oak, poplar, hickory, &ic. The soil on 

 the hills being very loose and fertile. — 10 feet. 



This interesting deposit of white water lime, extends from the 

 heads of Sunfish creek, across the heads of the Little Muskingum, 

 over to the east fork of Duck creek, of an average width of six or 

 eight miles, cropping out at various places, where the runs have cut 

 away the superincumbent strata to a sufficient depth. 



Calcareous Breccia or Fragmentary Lime rocJc. 



About eight miles north west of the water lime beds, is found a 

 very interesting deposit of fragmentary lime rock. This bed is on 

 one of the southerly branches of Will's creek, two miles from Sum- 

 mersville, which is seated on the dividing ridge between the waters 

 of the latter creek and those of Duck creek and Little Muskingum. 

 A part of the same water which falls on this ridge, runs into the 

 Muskingum river, above Zanesville, and apart into the Ohio, near 

 Marietta. The waters of Will's creek, are deep and sluggish, while 

 those on the south side of the ridge are rapid and shallow. The 

 soil on the north side of the ridge is black and loose with a large 

 proportion of sugar trees and yellow poplar amongst the growth 

 of the forest. On the south side the soil is lighter colored, and the 

 timber mostly oak, both indications of peculiar rock formations. 

 The one is more calcareous, the other more argillaceous.
