STRI.E OF THE SCIOTO LOBE. 349 



bench of rock at the west side of the creek bed, bearing S. 37° W. It 

 consists of a multitude of fine lines on a blue fossiliferou.s limestone of 

 Lower Silurian age. 



6. Chamberlin has reported strise on Andersons Fork southwest of 

 Reesville, bearing S. 45°-56° W} 



7. On the east side of the Wilmington and Xenia pike near the top of 

 the north bluff of Csesars Creek, in Greene County, are several glaciated 

 exposures, bearing S. 40° W. (magnetic). 



8. Near New Jasper, Greene County, in Bickett's quarry, south of the 

 Xenia and New Jasper pike, the rock surface is planed to glassy smoothness 

 and covered with strise, the majority of which beai' W. 5° N., but thev range 

 from W. 2° N. to W. 20° N. (magnetic). The Avestward movement was 

 determined by the examination of a cherty prominence in the stone, the 

 east side being the stoss side. 



9. At Conklin's quarry, near New Jasper, a short distance east of 

 Bickett's quarry, on the bank of Caesars Creek, bearing of nearly all tlie 

 striffi about W. 17° N. This rock, because of its hardness, is not planed 

 down like that in Bickett's quarry. There are many depressions and furrows 

 so striated as to indicate a westward movement, the strongest striation and 

 heaviest planing being on the west side of such furrows as were too deep 

 for the ice to striate to the bottom. 



OUTER BORDER PHENOMENA. 



The earlier drift and its silt capping having been discussed, it remains 

 only to discuss the fluvial plains. There are two streams, Todds Fork and 

 the East Fork of Little Miami, which lead from the moraine under discussion 

 into the outer border district, and whose valleys were available for the escape 

 of glacial waters at the time the moraine was forming. The East Fork was 

 not examined for evidences of glacial streams, but Todds Foi'k was found to 

 carry renmants of a gravel terrace which is apparently of the same age as 

 the moraine. At the outer border of the moraine just above Clarksville the 

 terrace is well exhibited, (Occupying nearly the whole width of a broad 

 valley. Its coimection with the moraine is not so close as in certain other 

 streams which the writer has examined within the glaciated district, but this 

 ma)' be due to the fact that the moraine does not fill the valley, but simply 

 dots the slope with scattering knolls.
