five forms all segments of tridmites and maybe one
of the [illegible].
The strata here lie in a syncline. At the base
of the [illegible]
reccm Hæelfimile oodles, out of which came the one
tridmite dead millt puccheels attached. These slates
are once or km fended and one sees on the west side
about 30 to 40 fut.
Then comes the banded shaly limestones and cal-
carous shales the whole may marked into a damogments
The thickness is somewhere between 60 mils per feet.
The layers are usually from 1/4 inch to 1/2 inch
thick, that gives of several miles and some up to six
or more miles reccm. At different irregular levels
reccm lenses of intra formation conglomerate. Some
of these show clear that they are churned up
and mixed at the time of their accumulation. In
this intraformational cong. there are also always
some of the rounded grain sands. These intraf, cong.
ranges from a few inches to 4 or 5 feet thick and in
length from a few yards to many yards long. Or
far as can be seen all are in that lenses.
Returned to this place in the afternoon
and Clentlar found a little lens that yielded
about two dozen tridmites. To one those tridmites
also look when Cambrian, though they are different
from those of the Ordovician.
