No 1019 A carr. I some [illegible] stem Smith will
be a Cordails. Section about 2 1/2 x 3 inches, cm.
No 1020 may be another wood cast,
No 1004 [illegible].
No 1006 A fine worm turner truck. No 880 and
881 the same thing. (drawing) Like this.
All of the fossil specimens seen this morning at the
Jacobsen are from a limestone quartzitic and fire conglomerates.
The quartz particles are all small usually 1/8 inch across
and all well rounded. Some have flatter shale angular
particles = intraformational. Very many in there is shale sample
that pressed, none are slates.
I can explain the fossil evidence test as Carbon-
iferous. [illegible] had reported his observations to Hoerner and
McCoy as Upper Ordovician on the basis that he had
seen a fragment about 3/8 inch across of a Trematops blade.
He is certain it was calcareous 'phosphatic' as this it had four

find neither. Was Hoerner taken these to New York?
The question I must ask Hoerner at Columbia Uni-
versity is did the Lepidodendron come from the same
formation as the rest of the fossils. If so there can be no
