ridge runs west to the long falls on Dead Riv-


or.
The rocks on a section from Lake Meantic to
Lexington are as follows; at the north end of
the lake there is a dark grey arenaceous schist
that frequently coutalns iron pyrites. On the
west side OF the lake and south of Victoria
river there is wrinkled arsilaceous scbist
with fossil brown slate having small cavities
filled with yelowsh brown powder The din
IS ). 40 e, 70o. These rocks are referred to-
tne upper Siluran by Sir VIM. Logan and they
e OK Gown the Chauoiere Biver to st. Fran
CHS. southwest We have found them in Duttou
anu on the boundary of New Hampshire. Their
eastern limit is near the head of Perry Stream
On their southern extension they pass into
mica schist. Following the road parallel with
Ihe lake SIX miles from the. lake Meagntic
tne rock changes and We have green
chioutic scaists, containing light green
epidolite nodules. The rock here dips N. $50
L. $50. Further up the lake we have fine dark
gray sandstones. These rocks were examined
t6y Sir WIN. Logan on the lake shore and by
nm they were referred to the Quebec granite
and were supposed to underlie the wrinked ar
gllaceo1s schist Just described. This seems quite
probable from their relations elsewhere. We
nave the same SUGGESTIONS of rocks In New
Hampshire in the vicinity of Connecticut lake.
Near the boundary of Quebec and Maine and
forming the watershed between Chaudiere
and Dead Rivers, we have a baud of granite
probably eruptive. Following the granite and
extending along Dead River for four or five
Il
which are apparently horizontal. The high
mountain ridge at the chain of lakes is an erup-
tive granite, and this is followed near the out
let of the lake by fine grained gneiss that dips
go and 700 W. and probably extends two miles
down the river. We then have for quarter of
mile granuous talcoid schisose rock that
dips 800 n, 200 w. This is followed by an i'm
pure serpentiGe of a very dark green color,
often asbestitorm in the joints and appearing
to form synclnal axis. 1t is followed on the
haas n.a,tla .fnIli
what coarser than that on the northeast, but
otherwise similar. This rock is SO cut by Joints
that it is impossible to determine the dip tho
the strip corresponds with the granular crystal
line rock northeast of the serpentine.
Leaving the vein aud following the old road
the next outcrop is a dark green crystallaceous
rock succeeded by quartzite that dips GO 20
Il. This is followed by a breccia composed of
greenish slate, quartLite and serpentine, and al
SO What appear to be reddish grains of falste
The breccia seems to be composed of rocks
found on either side of it as it is followed in the
southeast by quartzite that dips $50 S 300 w.
At Eustis village, extending mile northwest
and three and q half miles southeast there is a
band OF tender fossil slate, generally of green
lsh gray color but having bands of light purple,
and southeast of the village bands of quartzite
This slate forms distinct synclinal axis On
the Megalloway River we have granular schis-
tose rocks quantities., serpentine and slate. The
similarity of these, with those on Dead River
makes it quite probable that the latter are a con-
tinuation of the former. Between Eustis village
and Mt. Bigelow, there is a greensh choritic
rock that passes into porphyrilIc gneiss. This
roc occupies large area in Dead River plan
taton; aud since a similar rock was seen at r g.
Lii and northwest in Athens and Wood Ponds,
acontnuous band may extend thirty miles north
ward. There is striking similarity in this rock
to one found in Northumberland, N. H., aud
southwark. Here, as at Littleton, N H., there
is band of Lower Heidelberg limestone. South
OF the green chlorltic gneiss there is a mica
schist or imperfect gneiss that resembles very
closely the White Mountain SERIES On the
west peak of Mt; Bigelow the dip is 500 N. On
the ridge extending from Mt Bigelow east,
where the road passes over it in r. IL, No. 2,
the rock is mica schist and dips 800 N, so w.
These rocks rest on a porphyritic gneiss that
outcrops a few rods South of the height of land.
This gneiss resembles the rock of the basin
northwest in the valley, and is followed in the
South in New Portland by grantoid
gneiss that resembles very closely that asso-
clated with the gnelss in the vicinity of the
White Mountains.
