"They are in thickness from 2 to 6 miles ruffled and bear fossils other than lony shales are replete with delicate byrsa and fossils. I cannot see how these beds can be Eden or higher Ottawa and they are certainly not Richmond. Perhaps they only turn out to be another those of the Lorraine. By barometer we made out that it is at least 212 feet from the lake to the uppermost flat from which the "Clinton" cliff starts. On springing up the trail at 46 feet above the lake come in a great abundance of large R. alternata but no Richmond fossils occur here. At 70 feet above the lake we get the first Strickmona, dumerisi and Streptelasma affluents. Thereon the first true Richmond. At 126 feet above the lake Columnaria, Tetracrinus and Othmatocervine turn up in abundance, and finally at 212 feet above the lake we are still on the Richmond but it is in all probability not far from the "Clinton" shales beneath the "Clinton" limestones. It would seem that the Eden beds are shales without conspicuous limestone bands, the
