Monday June 13 - 1910 Kirkstom In the Cement abandoned quarries near the stone yard. The contact of the Cotteshill on the steeply upturned Hudon Riven sandstone, Mr. enigmatically here or any thing to direct my attention to a fact well other than the circular unem [illegible]. The basal layer of the Cotteshill in a coarse crystalline grind of Li. with ferricrete, the contact is slightly wave but there is not a sign of sand or pebbles between the Cotteshill and the Hudon River. Mr limestone conglomerate to Hudon River pebbles in the base Cotteshill layers. In some of the hollows there is a quarter inch of sand and lime. In the fallen down blocks from above the Rendall cement (the cement layers were quarried out) there is another sharp contact but one not representing a time break. The basal layers of these blocks consist of thin bedded dur estone limestone with thin streaks of impure Li. of about 6 feet in thickness followed by a 5 foot thick zone of stromatopora. The upper surface of the zone is knotty and in the cervices there is a well laminated shale with pieces of the stromatopora free involved. On this follows a durc or hard birdseye limestone without lamination for about 18 inches.
