Radial No. If, : Course south, 51p° east. 



Osnaburg, Stark Co., 574' (N.) ; to valley of Sandy, 11 miles, 540' 

 (W.) ; descent 34 feet. 



Radial No. 5 : Course south, 1^8° east. 



In the only instance of a reverse dip on this line, the rise is no 

 greater than occurs locally in several mines, or 32 feet. 



New Chambersburg, Columbiana Co., 629' (W.); Lynchburg, 6 

 miles, 540 / to 560' (W.) ; 1 mile beyond Hanover Station, 592' (W.) ; 

 Salineville, 7 miles, 283' (W.) ; Irondale, 6 miles, 330' (W.); Ohio 

 River, 5 miles above Steubenville, 12 miles, 125'? (Briggs). On 

 this line- I conceive that Seam No. 6, at New Chambersburg and 

 Hanover, is not the same as the " Big Seam " at Salineville, called 

 also No. 6, and am quite confident that the " Big Seam'' at Irondale 

 and Hammond's Station is not the same as the Salineville bed. As 

 to the latter, the accompanying diagram and levels explain the situ- 

 ation.

A. 



In the space of four miles, represented by this profile, decided 

 changes have taken place in the geological structure. At Salineville 

 there are two workable beds of coal, and two thin ones not wrought, 

 making four. One is about 80' above the Strip vein, and the other 

 36' below the great seam, alias No. 6. At Hammondsville there are 

 six, and as the two groups are traced together some of the seams 

 disappear. When the profiles are brought together and compared at 

 Bridge 42, the Salineville strip (2) is further than usual above No. 1
