inlets up to 20 feet above sea-level, but the present writer could
not convince himself that these were present. The very marked
wave-cut benches seen in Skidegate inlet, Masset inlet, and on
the west coast (Plates I and VIIIB) which are now virtually
at high tide level, may indicate a recent uplift; though Dawson!
considers them to have formed at this level owing to the pro-
tection of the rocks below high tide mark by sea weeds.

Around Skidegate inlet were noted several of the heaps of
recent shells mixed with soil, decayed sea-weed, and gravel,
that are such a common feature of the Puget Sound region.?

These shell heaps contained numerous shells and many
single and broken valves. It seems quite probable that the
heaps represent an upraised beach deposit.

CORRELATION..

The following table of the formations of Graham island,
compared with those of neighbouring districts, will show at a
glance the relations between them. The close geological relations
of Graham island and Vancouver island are well brought out,
also the absence from this insular province of the upper Jurassic
and Lower Cretaceous stratified formations of the Alaska
province.
