July 11. Tall Head Cove and mouth. The reddish chalk and sandstone, there are 3 sections taken for the book. Skin Shelly Crest. On the north side of this cliff is the zone of over three feet thick. Cav Shale argl, further the fossils are water worn, one of the fossils underneath. are fresh chunks. No shreds into the grey chalks. All is here much faded and in places marked. Then follows a course to cylomantic eric zone line have been previously. All stand on end, it's quite with folds are. Here the stone section ends and 5.40 P.M. we go aboard our boat and are taken back to Fox Island River camp. For three hours today all of us conduct collecting forms in the Tallo Shale series. The one surprising find is a large fossil milk Phyllogaster. Otherwise we get the same species collected in 1910, but far less of trilobites. In fact our collection of trilobites is for fine food. Just we could not get none. The forms are all marked ac- cording to zones, three in the chalks with proptilite, and 2 in the lime stone range with Proschikfos. The Cav Shale cylomante site like are the succeeding strata are much crushed and stored over one another. This for this reason that one cannot always determine the structures, and as for the throat arm of the Upper Ordovician zone this is generally out of the question. So back to camp and supper at 7 P.M.
