towards the north and east, forming
precipices about ten feet high, facing in that direction, and running
like a wall across the country. In many places, however, and
particularly at Cape Krusenstern, the strata terminate in magnificent
cliffs upwards of two hundred feet high, the country in the interior
remaining level. Mount Barrow is a small hill of limestone, of a
remarkable form, being a natural fortification surrounded by a moat. The
coast line is indented by shallow bays, and skirted by rocks and
islands.

In the whole country occupied by this formation, the ground is covered
with slaty fragments, sometimes to the depth of three feet or more.
These slates appear to have been detached from the strata they cover, by
the freezing of the water, which insinuates itself betwixt their layers.
At Cape Bexley, the fragments of dolomite cover the ground to the
exclusion of all other soil; and in a walk of several miles, I did not
see the vestige of a vegetable, except a small green scum upon some
stones that formed the lining of a pond which had dried up. In this
neighbourhood there are a number of straight furrows a foot deep, as if
a plough had been drawn through the loose fragments. After many
conjectures as to the cause of this phenomenon, I ascertained that the
furrows had their origin in fissures of the strata lying underneath.

At the commencement of this formation between Point Tinney and Point
Clifton, the coast is low, and a stream of considerable magnitude, named
Croker River, together with many rivulets, flow into the sea. Its
termination to the southward of Cape Hearne is also marked by a low
coast line, which is bounded by the bold rocky hills of Cape Kendall.

FORMATION SIMILAR TO THAT AT CAPE LYON.

The beach between Cape Hearne and Cape Kendall is in some places
composed of slate-clay, and of a clay resembling wacke. Many large
boulders of greenstone occur there. Cape Kendall is a projecting rocky
point, about five or six hundred feet high, and nearly precipitous on
three sides, which are washed by the sea. On the north, its rocks
consist entirely of greenstone, but on the south side of the Cape the
greenstone in lofty columns reposes on thin-slaty beds of fine-grained,
bluish-gray limestone. Back's Inlet presents on each side a succession
of lofty precipitous headlands, which have the shape termed, by seamen,
"the gunner's quoin." Most of the islands and points near the mouth of
the Coppermine have
