and considerable of it has been removed within the past few 
years. 
5. The Machias Moraine.—This is situated about five miles 
south of Machias village, near the first fork of the road found 
in going in that direction. It extends from Englishman's 
River northeastward for about three-fourths of a mile to near 
an arm of thesea. It is interrupted for a few rods by a swamp 
and a small hill and then begins again. The part most clearly 
a terminal moraine lies west of the road leading south from 
Machias. It is a ridge which rises rather steeply on each side 
to a height of from fifteen to twenty-five feet above the plain 
of marine clay in which it is situated. At one place the de- 
posit is wider and is double, the two ridges being separated by 
a shallow depression which is not, however, a kettle-hole. The 
southern slope of the ridge shows many bowlders from one to 
four feet in diameter, while just beyond the crest on the north- 
ern slope are several feet of stratified sand, gravel and pebbles. 
This probably was the result of the Champlain surf which 
broke on the southern slope and washed the finer drift over 
the ridge beyond the reach of the undertow and left it strati- 
fied. on the northern slope. At least the western portion of 
this formation must be a terminal moraine, though somewhat 
different from some of the others here described. 
6. The Waldoboro Moraine-—This is somewhat more than 
five miles long, with a few short gaps. 
On the west this moraine appears to begin a short distance 
west of Winslow’s Mills, a way station of the Knox and Lin- 
coln railroad, situated about three miles northwest of the vil- 
lage of Waldoboro. These mills are on the Medomac River, a 
stream about twenty-five miles long, which empties into the 
sea at Waldoboro. For several miles north of Winslow’s the 
Medomac has been flowing nearly south through a gently roll- 
ing plain, but near the mills the valley is encroached upon by 
a hill which here rises on the eastern side of the stream to a 
height of about 200 feet above the sea. This hill slopes north- 
ward und within a mile sinks to a level with the Medomac. 
On the west.of the stream there is a moderately steep slope, 
but the hill is not so high as that on the east side of the valley. 
The moraine appears to begin on the slopes of this hill about 
one-fourth of a mile west of the Medomac and at an elevation 
of about seventy feet above the stream. ‘There are here three 
nearly parallel ridges, the most southern one being only a few 
rods long and eight to ten feet high. The steepness of the 
slopes of these ridges and their irregular outline is in marked 
contrast with the flowing curves and rounded outlines of the 
granitic till of this region. The two more northern moraines
