It is remarkable how scarce the buchisprds are. All that we saw today are small Rafinesquina with a median keel.
Torohyle or Jan has found all the entire trilobites,
Bygga or saw one today.
June 11 is essentially a heavy bedded finely laminated
that slathers into a shaly gravel under the influence of the
weather.
June 10 is also heavily bedded and shatters into gravel on
weathering but in some one presion. It is far less fossiliferous
than June 11 but the species and especially the gastropods
are apparently the same as those of the higher zone.
Of Euryptomites it is impossible to get good material because
the chambers are filled with coarse crystals of calcite and
it is only the body chamber and 2 to 4 from first chambers
that are filled with mud. Then too many of the shells
were rotten before covered as the under side has broken down
and flattened before fossilized.
Nearby all the Endocrinatidae were also rotted before
covered as the under side is nearly always gone. The chambers
are nearly always filled with mud but the endocore is
nearly always crystalline calcite except the outer part.
The strike near the fifth range M-70 ft. Dip 12 deg.
One and half miles farther inland strike N-40 ft. Dip 10 deg.
Saw a piece of the Lower Cambrian conglomerate of Labrador
as an erratic today. It may also have come from
the eastward area there seems to be L. Cambrian.
