"As one could not see other outcrops in
this town one proceeded on to another one
about 1/4 miles north Craigleith. Here at 74
ft above the lake we are still in the typical dark
Caulmaeus shales like that of some of the
Utica, they are now Triarthrus spinosus
Endreous prteiforme, Orthoceras prteiforme
and finally a Leptolrbus. A little higher up
are set Leptolrbus, ostracda and a diflo-
graphtid in abundance but no specimens.
At 10 ft below the high tenace in all
grumist shales, got Calymene senaria (Triarthrus)
Plec. suriceus, dol. testudinaria and Trinucleus
coenctricus. This is about 140 ft above the lake
level. Downon the edge of the material at this
level are at least 20 ft down is unmistakably
the blue shale that one saw yesterday in the
Lower Richmond, Does this mean that the Utica
shades into the Eden and that about 180 to
215 ft of what one called Lower Richmondia
is really Eden. If so there should be a
break between these Eden shales and the
strata with Catagzeza erraticca and
Ordodopsin philadipsonis [Later there is
no such in the Cincinnati series]."
