Tuesday August 9-1910 Cow Head. In the morning returned to the Phyllograpthus beds discovered yesterday. This is taken to be in the lower part of zone 15 on Cow Head peninsula, but is not necessarily at the base of the division. It appears higher than the upper contact of the North side of the peninsula, Richardson says it is in the lower part of zone 15. For more material and added it to the collection of yesterday. Proceeding one through the north end of Cow Cove and about 15 to 20 feet above the lowest Phyllograpthus one or came up on another graphite bed. These are marked as of today and "graphite zone 2. Still further on we came upon two other graphite zones that are about 20 to 30 feet above those of zone 2. These are all the same large Leiozula like Helomella that we collected in zone No. 1 and No. 2. These are common but are hard to get out of the flint graves. With them are associated Orbitulidae rather large for or low an horizon. At the highest level occur the elongate Phyllograpthus. These are all marked zone 3. The graphite zones are associated with much redder flint that must be flint of destruction and diagenetic change. There is a good deal of this flint and it is more persistent than the Rock shale and as a rule iron ore than the limestones. The hashicords occurs in the shale (limestone) and in the tops surfaces of the flint. In one place we came upon one that had been chopped out by Richardson nearly 50 years ago. The surfaces of these flint layers are often covered with small rounded pebbles = local thin sheets of conglomerates. In other places the limestones are persistent almost all
