2933 P.R.R.
In the cut 1/8 miles last of Principio Station.
The "dense variegated clay" from rail road cut of that least 20 feet are very red almost crimson.
These, are clays somewhat gritty and distinctly
or rather mottled
but irregularly variegated. Did not see here the
white clay in strata gone. Barrel has clay
of this Patapsco gone from about 25 foot above rail
road track. Style of come in advance from clay
samples of the Baritan. This is the Baritan that we
find the iron ore.
Farther east lower strata, the Patuxent comes
in. There are more sandy beds, sometimes variegated,
during an abundance of iron. These iron layers have at
times considerable flaky remain for sandy nature. One
large piece with a concave surface had a regular
dotted appearance. Have some fragment of it and also
some of the ovoid. The iron ore pure Barrel the
idea of several iron segregation. There are also had
evidence that the layers own cracked mud deposits, if in
drift iron had been
Barrel for the evidence
this evidence that is once certain to establish the
nature of them deposits to be rather cultivated,
marks in proximity of the sea. In other case
the Patuxent when I clear sand maybe 5 or
shallows den, filling up a depositing continental deposits.
