separated from it by a space of several miles, as far down as the bend of 

 the stream near Franklin, Pa. In southwestern New York and in Warren 

 County, Pa., it has a breadth of but 3 or 4 miles, being narrower here than 

 in any other part of the district examined. In western Warren County it 

 curves to the southwest, and maintains this course throug-h southeastern 

 Crawford County. Its breadth increases in the latter county to about 7 

 miles at the south line. Near the corner of Crawford, Mercer, and Venango 

 counties it swings southward, and at its curve has a breadth of 15 miles, 

 the greatest breadth exhibited anywhere irithe eastern limb. 



From this point it departs more widely from the Allegheny. The 

 outer border touches the villages of Harrisville, Centerville, and West 

 Liberty in Butler County, and at the latter village swings abruptlj^ west- 

 ward, entering Lawrence Coxinty near Rose Point. The inner border in 

 this portion is not so easily mapped as the outer, being much less regular 

 and presenting a less marked contrast to adjacent districts. 



Around the southern end of the lobe (in Lawrence and Beaver coun- 

 ties. Pa., and Columbiana and Mahoning counties, Ohio) the morainic 

 system spreads out to a breadth of 15 miles or more. The southernmost 

 point reached by it is in the vicinity of Bayard, in southwestern Colum- 

 biana County, Ohio. In eastern Stark County the belt is double, there 

 being a feeble outer member which passes from Bayard north of west near 

 Osnaburg to Canton, while the main moraine passes northwest through 

 Freeburg, Strasburg, Barryville, and Marlboro to Hartsville, near which it 

 meets the main moraine belonging to the shoulder or shelf of the Scioto 

 lobe. The outer member connects at Canton with the outer moraine of this 

 shoulder. 



From Canton northward, nearly to Chardon, a distance of about 50 

 miles, there is a massive interlobate belt which, from Canton to the latitude 

 of Kent, maintains a breadth of 12 to 15 miles, but becomes narrower north 

 from there, terminating a few miles south of Chardon, with a width of 

 scarcely a mile. It is r)robable that the greater part, if not all, of the 

 interlobate belt that lies north of Kent and west of the Cuyahoga River 

 was formed from the west, since all the strise yet discovered on that side of 

 the river have a bearing east of south ; but the portion on the east side from 

 Kent northward, as indicated by strise beai'ing west of south, apparently 

 belongs to the Orand River lobe. South from Kent the line of junction of
