the State line. It joins the main system not far from Balch’s 
Pond. — 
Length, about 10 miles. 
XXVIII b. Little Ossipee Kame-Plains. 
These extend eastward from the main system in Shapleigh to meet 
XXVIII a south of Limerick. Length five miles. Near North 
Shapleigh, in the angle between these plains and those extending 
down the Mousam, is a flat plain of fine sand. It seems to mark the 
site of a lake whose barriers on three sides were the kame-plains, 
assisted perhaps by the ice, while a range of hills is on the remain- 
ing side. Although the kame systems found in lee of the White 
Mountains are not so long as those in the eastern part of the 
State, yet the amount of classified material found in them is vastly 
greater. This system unmistakably branches like a river at its delta. 
XXIX. Acton — Wells System. 
Near the top of a granitic range and about one mile north of South 
Acton, two ridges begin within a short distance of each other and 
run southward by quite different courses, one keeping in a valley that 
leads eastward into the Mousam, and soon leaving it and making its 
way southward over a low col and along a low valley, the other zig- 
zageing along the top and sides of a hill one hundred or more feet 
above it. They soon unite with a third small ridge and together ex- 
tend through the eastern part of Lebanon, and through North Ber- 
wick into Wells. From Lebanon south, the system takes the form of 
reticulated plains. A large ridge in Wells which re-curves north- 
eastward and is known as Maryland Ridge may belong to this sys- 
tem or to XXVIII or to both. The plains of this system and 
XXVIII seem to unite not far north of North Berwick Village. A 
few ridges south of Garvin’s Pond may form a northern extension of 
this series but the connection is obscure. In Acton the gravel of this 
system is very angular, most of it showing hardly any signs of water 
wear, although plainly classified by water. 
Length 28 miles. 
XXX. West Lebanon System. 
Extends from North-east Pond along a low pass through the west- 
ern part of Lebanon, throwing out scattered plains in various direc- 
tions. Not fully explored. May extend to Berwick. 
Length perhaps 8 miles. 
XXXI. East Rochester — Dover System. 
A series of kames begins in the valley of Salmon Falls River not
