232 MAN AND THE GLACIAL PERIOD. 



the imbedded relics of man which definitely connect him 

 with the great Ice age. These have now been found in 

 the glacial terraces of the Delaware Eiver at Trenton, 

 X. J. ; in similar terraces in the valley of the Tuscarawas 

 River at New Comerstown, and in the valley of the Little 

 Miami at Loveland and Madisonville, in Ohio; on the 

 East Fork of White River, at Medora, Ind. ; and still, 

 again, at Little Falls, in the trough of the Mississippi, some 

 distance above Minneapolis, Minn. 



I append a list of the points at which various streams 

 from the Atlantic Ocean to the Mississippi River emerge 

 from the glacial boundary, and below which the terraces 

 are specially prominent. Of course, with the retreat of the 

 ice, the formation of the terraces continued northward in 

 the glaciated area to a greater or less distance, according 

 to the extent of the valley or to the length of time dur- 

 ing which the drainage was temporarily turned into it. 

 These points of emergence are : In the Delaware Valley, 

 at Belvidere, N. J. ; in the Susquehanna, at Beach Haven, 

 Pa. ; in the Conewango, at Ackley, Warren County ; in 

 Oil Creek, above Titusville : in French Creek, a little 

 above Franklin ; in Beaver Creek, at Chewtown, .Lawrence 

 County ; on the Middle Fork of Little Beaver, near New 

 Lisbon, Ohio ; on the east branch of Sandy Creek, at East 

 Rochester, Columbiana County ; on the Nimishillin, at 

 Canton, Stark County ; on the Tuscarawas, at Bolivar ; on 

 Sugar Creek, at Beech City ; on the Killbuck, at Millers- 

 burg, Holmes County ; on the Mohican, near the northeast 

 corner of Knox County ; on the Licking River, at Newark ; 

 on Jonathan Creek, Perry County ; on the Hocking, at 

 Lancaster; on the Scioto, at Hopetown, just above Chilli- 

 cothe ; on Paint Creek, and its various tributaries, between 

 Chillicothe and Bainbridge ; and on the Wabash, above 

 New Harmony, Ind. ; to which may be added the Ohio 

 River itself, at its junction with the Miami, near Lawrencc- 

 burg.
