South of the Terminal Moraine. 279 
(11.) Prof. J. F. Carll in his valuable report on the Oil 
Regions’ includes an extended discussion of the glacial drift, 
and holds that 
northern branch valleys and no northern detritus in the southern 
eg alleys, . . . it follows that the northern ice-flow, south- 
ard, met a southern ice-flow, SAN Ap and both moved west- 
tty side by side.”* He makes the origin of this northward 
flowing glacier in the “upper branch valleys of the Allegheny 
River in Potter and M’Kean counties,” and believes’ that the 
Salamanca “ Botk | City ” was formed by glacial erosion. 
These eleven localities, each lying south of the Palen 
moraine, some of them considerably so, are, I believe, the on 
ones in Pennsylvania south of that line which have been eerie 
as showing evidences of glaciation by geologists of acknowl- 
edged ability. Several local writers in the State have mistaken 
Weathered trap bowlders for * erratics, or fallen into 
similar obvious errors,” but these are not w orthy of mention. 
If these statements, givén in ach detail, remain | unquestioned 
- facts, it must be granted that the “ terminal sla so- 
tinguish glaciated from non-glaciated regions are insufficient. 
Tt seems to be of importance therefore, that any investigations 
of the terminal moraine should be supplemented by Sibi 
Tr 4 proposed, therefore, to review each of the above eleven
