provisionally marked as a part of system VIII, and if correctly, then 
we have a kame-system branching like a river at its delta. The 
country is wild and not personally explored by me, but I have state- 
ments from a number of observers which show that system VIII con- 
nects down this way. 
Length about 17 miles. 
IX. Seboois— Enfield — Deblois System. 
This system appears to begin in No. 7, R. 7, within a few miles of 
the source of system VIII. It passes Seboois farm, its course being 
parellel to the west branch of the Seboois Stream. It ends, so far as 
can yet be made out, right in front of the gorge by which Seboois 
Stream makes its way through the Katahdin Highlands. In the gorge 
it has been wholly washed away and re-classified for most of the way 
for twenty or twenty-five miles, which is not surprising when we con- 
sider the narrowness of the valley and the vast currents of which we 
see the signs as having swept down the defile during the valley drift 
period. Where the valley widens the kame begins and continues 
fourteen miles to Medway, where it crosses the main Penobscot River 
and turns easterly for about two miles. Here the open Penobscot 
valley lay right before it, but it makes an abrupt bend through a total 
deflection angle of nearly 135° and runs southwest along the valley 
of the Pattagumpus. It then follows the Maddunkeunk to Chester, 
turns scuth-westerly and soon more easterly, crosses the Penobscot 
again at South Lincoln (Hockamoc Island) and thence continues 
through Enfield, Passadumkeag, Greenbush, Greenfield, and so on 
to Aurora and Deblois. 
The principal features of this kame are the following. In Passa- 
dumkeag and Greenbush it has been under the sea and well illus- 
trates the action of the marine waves and currents in modifying 
the kames. In Greenbush it is in three places piled up into a 
kind of plain from 40 to 120 feet higher than the rest of the kame. 
These are locally known as “mountains” or “pinnacles,’’ and are a 
remarkable feature of the landscape, being found in the midst of a 
great clay plain. In Greenfield the Katahdin kame unites with this 
one near the shore line of the Champlain sea and both seem to have 
thrown out plains (probably during tht very last of the kame period) 
and then the sea has curiously washed and re-classified them. Bars, 
swells, flats, plains—the whole country is unique and has an inde- 
finable lack of character for a kame country. The flanks of the pin- 
nacles above mentioned are strewn with boulders, the work of ice-
