southeast of the Unger barn. The stratum is black and 18 

 inches thick lying at 1082 above sea. This exposure is about 

 H miles south, and 2j miles east of the Bingham outcrop, and 

 lies 10 feet higher. As noted in the Lower outcrop there is no 

 evidence of dip in this locality toward the south or south-east so 

 far as the writer has found. A few hundred yards above the 

 Unger outcrop and directly in the southwest corner of Canfield 

 Township on the Ewing farm a bed of coal lies at 1115 feet above 

 sea and a few feet beneath this a second bed. The top of the 

 upper bed is 83 feet above the Unger limestone, and the bottom 

 of the 13 foot black shale on the Bingham farm lies 24 feet higher 

 than the Bingham limestone or the top of the shale 37 feet 

 higher. Above the limestone at both places there is sandstone; 

 above the black shale on the Bingham farm and above the coal 

 on the Ewing farm sandstone occurs. With no evidence of dip 

 and with close correspondence of the strata in elevations and 

 character, the conclusion that the limestone at Unger's is the 

 Howenstein and that the Ewing coals are the equivalent of the 

 black shale at Bingham's is inevitable. The coal on the Ewing 

 farm was identified by Dr. Orton as the Canfield cannel coal, and 

 the fragments of limestone found at the opening of the Ewing 

 mine as the ferriferous limestone. [Ohio Geol. Sur. Vol. V, p. 31.] 

 He further indicates that the dip is 15 or 20 per mile toward the 

 southeast in this locality. Upon what is it based is not stated. 

 The writer finds only evidence of little or no dip at all, and is 

 unable to regard the Ewing coal other than that beneath the 

 Putnam Hill limestone, and that the fragments of limestone 

 found by Dr. Orton belong to that strattmi. A comparison of 

 the limestones, coals, and their elevations on the east side of 

 Canfield Township with those at Lowellville leads to no other 

 conclusion than that the Canfield Cannel Coal is the coal beneath 

 the Vanport limestone as Dr. Orton identified it. The following 

 are the elevations of the limestones on Meander Creek and those 

 on the east side of Canfield Township: 



This table is the writer's interpretation of his findings based 

 upon the number of strata, their elevations and their intervals. 

 (1 ), (2), and (3) correspond well. (4) on the east side of Canfield 

 clearly lies lower than usual but unmistakable. 



The Ewing coal certainly appears to mark the Putnam Hill 

 horizon in the southwest corner of Canfield Township.
