Belvidere, Ill., Thursday, Sept. 10 - 1914.
Left at 10.29 on the C.P.R., arriving
at 10.55. Stopping at Delaware House.
Starting out south along the Iron Turnpike,
one is in the Salina here. Several creels in the syncline
here. It consists of zones of red sandy shales from
2 foot to others of 7 to 20 feet separated by zones of
sandstones from 2 to 6 feet. Here are [illegible] zones of
green shales. At my returns I see some impure lime-
stone, not exactly a marlstone, one of which had a
considerable quantity of cornishware broken in diameters from
1 to 5 inches; I thought like those have seen in the Charlus.
Going along farther I see that the Salina is best de-
scribed as a series of red shales with many lenses of
and impure red sandstones
green coarse decided can hide out sandstones. These
lenses are of short distances across and at times cut
occasionally are very long, they are cutting quite far,
deeply into the red shales & It looks like streams more cutly
clear and
into the sandstone. The red shales are usually slaty due
to pressure and a few many have zones of vesicular ver-
tical dikes - caliche pipes of some dry climate, due to the
character than any thing of the medium.
