Ottawa Tuesday, Aug 5-1913. Visited the quarries about Hull. There are a number of faults in the Trenton series with throws of 10 to 75 feet. In consequence some of the places are considerably disturbed beds. Fossils are hard to pick. In the Trentredid series seen Rafinesquina del- Toidea, R. alternata, Qolmanella testudinaria, Etrorcrinus canadensis, Pleuroptoma, Fresipira, and many trepostomata byzrea. The crinoid layers is bolar thin here. All of these horizons appear to me to be in the lower half of the Trenton. Then follows below the Pleuroptites beds, next the spongy zone with large Ommatoma or Lophopira, P. detindus, Ophthalamia, Sheptilasma corniculum, Plechbith plicatella and and finally at the very top the zone of Cyclaspina fissulata. These higher Trenton zones are more or less in progression.
