Whittlesey.] 194 [November 18, 



Cleveland and Pittsburg Railroad, south side, Section 14, Franklin 

 township, 477' (W.); sides fourteen miles; dip south 20° east, 16' 

 per mile. 



Passing over the summit from Franklin to Salineville, 6 miles, 

 about southeast, the " Big Seam " (No. 6) is at the Station 283' A., 

 or 257' below the coal near Hanover Station, Forty to fifty feet 

 above it is the "Strip Vein" (No. 7), in which I have three local 

 triangles, with sides of three-fourths of a mile to a mile and a quarter. 

 The dip varies from north 70° to north 82° east, and is very rapid, 

 being from 80' to 100' per mile. Proceeding westward it is much 

 less. Here is a local rise of 40' to the north, in less than forty rods, 

 where the bed is cut out entirely. If this is due to a wrinkle of the 

 strata, caused by dynamical forces, connected with the Pennsylvania 

 uplifts, the local bearing, instead of being nearly north and south, 

 should be northeast and southwest. On the Big Sandy, thirteen 

 miles distant to the north, the bearing is nearly east and west, and 

 consequently not parallel with either the Salineville local trough, or 

 that of the Alleghanies. 



I have already noticed the supposed rise of Salineville No. 6, to 

 meet the Irondale No. 6, or "NiselyBig Seam." The farmer has 

 been traced from Salineville in that direction three miles, or halfway, 

 and found to be 223' A. A mile farther on, at Clark's tank on the 

 Railroad, are beds Nos. 3 and 4 of the Reports, only 18' to 20' apart, 

 on the same level with the Salineville No. 6. 



As the Nisely Great Seam is about 200' above the " Strip Vein " of 

 Hammondsville, at Clark's tank it should be about 425' A. Two 

 miles farther on,5n a southeast direction down the valley of Yellow 

 Creek, it is 330' or 107' Uglier than at Bridge 42. 



To account for this requires a rapid reverse dip to the northwest, 

 between Salineville and Irondale, of which the levels show no evi- 

 dence beyond the common local undulations. From Hammond's 

 Station to the Ohio the elevations are numerous in both No. 6 and 

 No. 4 seams ; both of them descending in that direction, but not 

 strictly conformable. 



No. 16. Coal Seam No. 6. Local. 



Hammond's Station. Mean of three planes, dip south 50° east, 

 57 feet per mile. Seam No. 4, or " Strip Vein," mean of three 

 planes, south 8° east, 63 feet per mile ; not conformable. 



In this seam is a. sag of 20.feet in one-fourth of a mile, the axis«j@f
