The great mass of our Blaspm conglomerate seen in
this cliff has come from the igneous mountains against which
the conglomerate rests. The bedding is irregular with
lenses of fire material. The Cliff stands of 100 or
more full height almost as a single bed. Whereon
bedding is shown it cannot be traced far laterally.
The carbonaceous shales here at Spicen Cove
reminds much of that at Joggins. As we have been
descending in the strata all the day, it is probable that
these beds are either on the top of 4 or are in Dr 3 of
Logan. They have thin beds of coal, Fletcher states of
11-9 inches, but I would not say more than a few
inches. Known carbonaceous beds we did not see
in the Joggins area except in 4 and 3. As there is
or smud of these dark shales, 75 foot or once, seem
inclined to regard them as in either 3 or 4.
From Fridays work it is clear that we con-
tinuously descended in the section and attained
