"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]."
