"The pieces are laid down at all angles, often the
stand edgewise. Some of these pieces bear Lower
Cambrian fossils, and in one block I got Ptychomenus
and Lingulella.
The most abundant pieces are
of a white tridoye like limestone, the same
as the great block seen 6 miles north of St. Albans.
Finally there are pieces of the sandy dolomite
and of a black colored dolomite, one much
further down in the Lower Cambrian series. Again
are some on or schist, no granite. Some of the boulders
of the marble like li. are five to six feet long.
We also saw some blue black shale pieces
included in the conglomerate. The great majority
of pieces are angular. Beneath the blue li
congl. we often saw a rounded dark slate, that
in places seems interlaid with gritty sand in
the beds. For these various occurrences ite
appears there is but one explanation. It is of true mile
recurrence to be of cliff origin, at the same offer
true of torrential rivers.
At 6 1/2 to 7 miles north of St. Albans we
saw much black slate that was gray similar to
the others, but it has nothing whatever!
