they are taken from my notes, are generally marked (W.), especially 

 where these differ from those of the Report, which are marked (N.). 

 If they are without either of these letters, they are from the Report, 

 or agree with mine. 



Radial No. 1. 



Coshocton County, west part, head of Simmon's Creek; course 

 east; elevation of No. 6, 487' to 500' above Lake Erie (Whittlesey); 

 in the west part of the county 477' (Newberry); mean 489' A.; 

 thence to Coshocton eight miles east, 248' (N.); to New Comers- 

 town, twelve miles, 292' (N.); descent in 20 miles, 197', or at the rate 

 of about 10' per mile. 



Coshocton is situated at the south end of the valley of Kilbuck, 

 which lies nearly north and south, and in which there is reported to 

 be a synclinal. The next synclinal is located in the valley of the 

 Tuscarawas, about thirty miles to the east, and lies also north and 

 south. This radial is therefore at right angles to the intermediate 

 anticlinal, if it exists, and the elevations of No. 6 across the end of it 

 are as follows (Report, p. 43), reckoning from west to east : Coshoc- 

 ton, 248'; New Comerstown, 293'; Lock 17, 295'; Port Washington, 

 260'; Uhricksville, 275'. These figures show no more differences 

 than are to be found in many large mines, and represent a stratum 

 substantially level, in this direction. This is accounted for in triangle 

 No. 2, which will be given below, by the fact that the general direc- 

 tion of this line is on the bearing of the beds. According to my 

 memoranda, however, the Uhricksville mines are materially higher 

 than is represented by the Report. 



Radial No. 2 : Course south, 77° east. 



Nashville, Holmes County, 688'; to near Millersburg, 111 miles, 

 583'; to New Castle, on the Tuscarawas, 19 miles, 352' (W.) ; descent 

 in 30-L miles, 336'; about 11 \ feet per mile. 



Radial No. 3 : Course south, 70° east. 



Fredericksburg, Wayne County, 600'; to Dundee, Tuscarawas Co., 

 12 miles, 558' (N.); Zoar, 11 miles, 462' (N.) ; 487' (W.) ; Perches' 

 Mill, valley of Connoten, 7 miles, about 400' (W.) ; descent in 30 

 miles, 200 feet, equal to 6 T 6 7 feet per mile.
