rds thick, which is composed of pebbles of granite, sienite, quartz,
lydian-stone, and compact limestone, all coated by a white powdery marl.
The dip of the strata at this place is slightly to the northward.

A few miles to the south-east of Wilmot Horton River the cliffs are six
hundred feet high, and present acclivities having an inclination of from
thirty to sixty degrees, formed of weathered slate-clay. Some beds of
alum-shale are visible at the foot of these cliffs, containing much
sulphate of alumina and masses of baked clay.

Two miles further along the coast the shaly strata were on fire, giving
out smoke, and beyond this the cliffs become much broken but less
precipitous, having fallen down in consequence of the consumption of the
combustible strata. These ruined cliffs gradually terminated in green
and sloping banks, whose summit was from one to two miles inland, and
about six hundred feet above the sea level. Considerable tracts of level
ground occurred occasionally betwixt these banks and the beach. Wherever
the ground was cut by ravines, beds of slate-clay were exposed. On
reaching the bottom of Franklin Bay, we observed the higher grounds
keeping an E.S.E. direction until lost to the view, becoming, however,
somewhat peaked in the outline.

SEA COAST.--LIMESTONE.

Parry's Peninsula, where it joins the mainland, is very low, consisting
mostly of gravel and sand, and is there greatly indented by shallow
bays, but it gradually increases in height towards Cape Parry. The bays
and inlets are separated from the sea by beaches composed of rolled
pieces of compact limestone; and which, although they are in places only
a few yards across, are several miles in length. The northern part of
Parry's Peninsula belongs entirely to a formation which appears from the
mineralogical characters of the stone composing the great mass of the
strata, and the organic remains observed in it, to be identical with the
limestone formations of Lakes Winipeg and Huron.

[Sidenotes: 202, 204] On the north side of Sellwood Bay, in lat. 69
degrees 42 minutes, cliffs about twenty feet high are composed of a
fine-grained[43] brownish dolomite, in angular distinct concretions, and
containing corallines and veins of calc-spar. [Sidenote: 203] In the
same neighbourhood there is a bed of grayish-black compact luculite with
drusses of calc-spar, very similar to the limestone which occurs in
highly inclined strata at the "Rock by the River S
