ridge about one-half a mile south-west of Leeds Junction appears to 
belong to this system. Along Sabattus Lake the gravels, if they 
are there, are covered by the clays. Near the south end of Sa- 
battus Lake a large ridge begins quite suddenly and within a mile 
expands into a plain three-fourths of a mile in diameter, flat topped, 
and a solid mass of sand and gravel, except near one edge where 
are a few funnels and lakelets. This plain is bordered by high, 
steep slopes on all sides, or would be but for the clays. which plainly 
overlie the gravels, and in some places come to near the top of the 
plain. ‘Then after a break of two or three miles there is another 
arge ridge perhaps one mile in length. Then comes another break 
of one-half a mile in the series, and then a high and broad ridge 
about one-half a mile long, and 116 feet by aneroid above the sur- 
rounding clay, and as the clay is quite deep in the vicinity, the ridge 
is probably 140 feet above the till. ‘This ridge is situated near Lis- 
bon village. From here kame gravels are found at intervals along 
the Androscoggin River, as far east as the mouth of Little River, 
where the river system is re-inforced by a local system which has 
come down the Little River valley from the direction of Litchfield. 
The sand plains of Brunswick and vicinity are of marine deposition, 
though the material may have originally been brought down by this 
kame-stream. In view of the long break in the system south of 
Leeds Junction, I provisionally mark the.main kame as reaching 
to Leeds, and the series of ridges found along the Sabattus and 
Androscoggin valleys as a probable continuation. The size of this 
system in Chesterville demands a large supply of water, and prob- 
ably a kame-stream ran down the Sandy River valley. If so, its 
gravels have been almost wholly re-classified into valley drift by 
the river, which is subject to violent floods, there being very few 
lakes or ponds in the valley. A low pass reaches from Rangeley 
Lake south-eastward to Phillips, but I could find no signs of any 
great overflow that way. Length from Chesterville to Lisbon, 55 
miles. 
XX a. Winthrop — Leeds Kames. 
An interrupted serieg of small ridges reaches from Leeds Junction 
to Winthrop village where it seems to run into Lake Maranocook 
Six miles to the north in Readfielda kame emerges from the lake and 
extends northward for one anda half miles. Probably the series 
extends under the lake. Juength from Winthrop to Leeds 12 miles. 
A short kame is found a little east of Mt. Vernon village, another
