Seite 20 - Tnlly limestone, but in the shaly strata for several hundred feet above. Therefore, if we wish to express precise correlation in our classification of American rocks, the line between Middle and Upper Devonian formations should be drawn at the base of the Tully limestone, to correspond with the usage of French, Belgian, German, and Russian geologists, who include Frasnein, Cuboides Schichten, and correlated zones in the Upper Devonian.
Seite 121 - ... and not on industrial characters. The requirements in the way of tools being very simple and the supply of material in the way of natural flakes and fragments of flint being very plentiful, the inventive powers of the population remained dormant for ages. Hammer and knife were the original tools. Both were picked up ready-made. A sharp-edged, natural flake served for one, and a nodule or fragment served for the other.

Seite 49 - The lower part of this shale resting on the Encrinal beds is completely filled with a small Orthis or Stenecesma (Ainbocixlia umbonata). This species so abounds that in some places there is scarcely enough shaly matter to cause the mass to cohere." In the second Ambocoelia zone (R), described elsewhere, A. umbonata has a remarkable development. Elsewhere in the section layers an inch or less in thickness were found which were almost completely made up of them. In actual numbers there are a great...
Seite 20 - Parallelism of the Paleozoic; Deposits of America with those of Europe," Hall says that the "line of demarcation between the Devonian and Silurian is at the base of the Upper Helderberg or at the bottom of the Schoharie grit. Verneuil proposed to unite the Marcellus shale, Hamilton shale, Tully limestone, and Genesee shale in one division, and make the Portage and Chemung the second of this period. He correlated the Chemung, Portage, Genesee, Tully, and Hamilton with the formations of Eifel and Devonshire;...
