flows, in my opinion. At the col dividing Union from Sunkhaze — 
waters the coarse moutonned slates are swept clean of everything’ 
except large boulders. Seldom in Maine does the lower till appear to 
have been eroded by the kame-streams, but here everything has 
that appearance. ‘The rocks are more bare on the line of the kame 
than elsewhere, but the region is so wild and the distribution of the 
till so irregular, that this may be only a freak of the till. A little te 
the east of this place the kame consists of a ridge of coarse slates and 
granite, otherwise for seven miles after entering the granitic region of 
the Mt. Desert Highlands the kame is almost wholly composed of 
slate, although the fields on either side are full of granite. The kame 
to the north of this point has passed through a region of slate. In 
Aurora this kame forms a magnificent double ridge fully one hun- 
dred feet high, called the Whales-back. 
Length of the system about 130 miles. 
It will be noticed that Systems VU, VIII and IX all end i in a great 
series of plains probably containing about two hundred square miles. 
I have called them the Deblois plains, from the name of the town 
in their centre. It was on these plains that the base line of the U. 
S. Coast Survey was measured. Within these plains are local plains 
of sedimentary clay, which may possibly point to local lakes during 
the kame period when the kames with their underlying ice might 
have enclosed a temporary lake. 
IX a. Staceyville— Salmon Stream Kame. 
Length about twenty miles from the south part of Staceyville, to 
join the main kame at the mouth of the Pattagumpus. 
IX aa. Salmon Stream Kame. 
A kame extends from near Salmon Stream Lake to join the last 
named kame not far from the Penobscot river. 
IX x. Mattakeunk Kame. 
A kame two or three miles long is found along the Mattakeunk 
stream, reaching from the Penobscot north. 
IX m. Sam Ayer’s Stream Kame. 
Length six or more miles along Sam Ayer’s Stream, above its 
junction with the Mattamiscontis. 
IX b. Katahdin Kame. + 
This probably begins near the west branch of the Penobscot at the 
mouth of Katahdin Stream. It then runs nearly east along Aybol 
Stream, and sometimes north-east, for about fventy miles to Millin- 
ocket Lake, thence south along Millinocket Stream, up the Nolles-
