88t G. H. Stone—Terminal Moraines in Maine. 
comes out to the road leading northward from Waldoboro to 
Union village. This road is made on top of the ridge for more 
than one mile, part of the way through a somewhat swampy re- 
gion which would be difficult of passage but for the natural 
embankment. Here also the marine clay appears to overlie the 
base of the moraine. Approaching the east line of the town of 
Waldoboro this road is about one-eighth of a mile north of the 
moraine, which becomes lower and less continuous, and seems 
to end within a short distance from the line between Waldo- 
boro and Warren. It ends within about one-fourth of a mile 
from the osar system which extends from Palermo to near 
Warren station on the K.& L. R. R. To the east lies a level 
country for a half mile or more, so that it is not cut off by a line 
of hills or other obvious barrier in that direction. 
The country lying east of the Medomac river and north 
of the moraine is diversified by numerous low hills, or per- 
haps it. had better be de- 
scribed as a rolling plain. I 
estimated that few if any of 
these hills rose more than 
about 100 feet above the sur- 
rounding level. The hills 
did not cause a gap in the 
| moraine except at two or 
three points. The country 
rock weathers so rapidly that 
the glacial scratches had dis- 
appeared from all the ex- ' 
posed ledges observed. The 
direction of glaciation near 
the moraine therefore was 
not determined. Some large 
ridges and heaps of till are 
found about a mile north of 
the end of this moraine, but 
their origin is uncertain. 
The elevation of the Wal- 
Scale of meles. doboro moraine is such that 
if it was deposited at the 
time when the sea stood at its highest level during the Cham- 
plain epoch, it must have been formed at a depth of from 50 
to 175 feet below the surface of the water. I did not find 
a good section showing clearly the relations of the moraine 
and the marine clay. Excavation will perhaps be needed in 
order to determine this important point. In the absence of 
conclusive evidence as to the time of the formation of the mo- 
raine, we can only avail ourselves of indirect evidence. In
