HOLMES COUNTY. 561 



enable me to give the entire dip of the rocks in this county, and to the 

 east, as accurately, probably, as it can be determined by this instrument. 

 Coal No. 1 (Motes' bank), in the south-east corner of Kfnox, is, in this 

 manner, found to be 207 feet above Millersburg; one and a half miles 

 east, at Jas. Williams' bank, 211 feet, rising a few feet in that distance. 

 In a ravine north of Judge Armour's, west line of Hardy township, and 

 about four miles east of last, it is 146 feet, the dip east being about 

 eighteen feet to the mile. At John Gary's bank, near Millersburg, and 

 two miles further east, it is seventy-six feet — dip east, forty feet to the 

 mile. 



Commencing on the western slope of the hills west of Saltillo, the 

 Blue Limestone is 220 feet above Millersburg. At its first outcrop, de- 

 scending from Saltillo to the east, it is 229 feet, having risen nine feet. 

 On the slope between Dowdy's Run and Parmersville, it is 218 feet, 

 having sunk eleven feet. On the slope east of Farmersville, it is 184 

 feet, and further east, in the lowest valley, 137 feet, having sunk eightj^, 

 one feet. Prom this place to a point east of Shanesville, it gradually rises 

 to 156 feet ; amount of rise, fourteen feet. It then steadily dips to the 

 east, and at its first disappearance west of the Tuscarawas, is seventeen 

 feet above Millersburg, the dip from the point of observation, east of 

 Shanesville, being seventy-nine feet. All the observations here, show a 

 dip towards these deeper valleys, indicating an intimate connection be- 

 tween the present topography and the undulations of the Coal Measure 

 rocks. Observations taken at remote points, will eliminate these undu 

 lations, and show a dip to the south-east, at a rate which will represent 

 the excess of the dip in that direction over the reverse dip, and not the 

 rate of dip at any particular place. From facts stated above, it will 

 also be evident that the dip of the difierent strata will not be the same, 

 nor always in the same direction. When a wedge-shaped formation oc- 

 cupies the interval between two coals or limestones, the dip of the t-^io 

 can not be the same. It follows that the identity of two coals, in distant 

 parts of the field, can be established with certainty only by laboriously 

 tracing the outcrops'throughout the whole field. The system of number- 

 ing, and the determination of the members of the series which are sub- 

 stantially persistent, will aiford great aid in this determination ; but 

 there are so many local, intrusive coals, and so great variation, both in 

 the character and thickness of the material filling the intervals, that a 

 section in one place will only approximately represent a section in 

 another ; so that a careful and painstaking study of all the members of 

 the series, is required in every township, to enable the explorer to reach 

 accurate results.
