methods of erosion would incise the rock slope, and a resulting 
bench and terrace would now indicate the course of this former 
overflow stream. 
Where the highway leading southeastward from Moravia to 
North Summer Hill skirts the southern slope of the rock salient 
facing Montville we note at about the I200-foot contour, the first 
evidence of one of these former stream courses. The appearance 
from the highway, however, is not suggestive of such a channel, 
but a short walk northward around the face of the salient leads 
one to a more conspicuous development of the former stream 
course. This point of overflow obviously taken by the water held 
in the valley eastward towards Morse Mill succeeded a higher 
channel which led the ponded waters about the brow of the hill 
and formed a conspicuous cliff and terrace extending about the 
prow and the southeastern part of the slope fairly parallel with 
the 1340-foot contour. Southward from this highway the course of 
the channel last traced drops, and at about one-quarter of a mile 
from the road it may be traced for some distance where it has 
smoothed out the morainic topography that characterizes the 
northern slope of Dry Run valley. Likewise, about one hundred 
feet lower in altitude may be traced the continuation of the first 
mentioned channel. 
On the southern wall of Dry Run valley there is noted a marked 
over-steepening, not due to an)/ lithological irregularity in the salient, 
which here is included within the district encompassed by a high- 
way extending to the east and another extending southward and 
then eastward. The case of a deserted stream course here, while 
apparent, is not so clear as in the two just described. 
The western slope of the hill south of Asbury is conspicuously 
free of drift, a condition due to the sweep of waters from the north 
between the ice and this hill. No pronounced bench was devel- 
oped, but the rock over quite a width and vertical range has been 
fairly well cleared of glacial rubbish. 
The slopes of many salients found on the east wall of Fall Creek 
valley also bear benches probably due to a similar cause. It is 
seen from the topographic map that this area is cut up by frequent 
and wide valleys, thus producing a medley of salients between 
which impounded waters escape successively to the lower levels, 
and in doing so, being held against the slope by ice, have channeled 
the rocks in varying degrees. I have not mapped these since in
