August 11-1918 Sunday. Table Head. and bright A fine cool Sunday morning, we start north on the fort path to a place a little more than 3 miles from our camp at the south end of Table Head. Here we see low cliffs extending north for many miles and along the strike of the rocks. The strata are thick beds of a dull-grey fine crystalline dolomite full of calcite interlenses. No fossils are seen. A very little of chert (strips) cropping out replacing the calcite strips. There are also small quartz geodes. We started to make the section 3 miles north of the south end of Table Head. Here the lower beds are exposed in a little rocky cave made in the upper part of the Reed Mountain and almost continuous use of green broken more whitish than shunier here. Pyritous chert followed a few feet higher by Euchasman (matter unknown) Coral-fern type spore and many flat gastropods, coming then a very large Helictoma beds (and was between 5 to 10 miles apart). There are in zone 2 division 3 of Richardson. Up to the block just north of Table Head Deuter made out 115 feet of thickness. He must abandon all of Richardson's descriptions as they do not fit the rocks as we see them. This division I is certainly the terminal beds of the Reed Mountain. They cannot be referred to the Chazy. The terminal beds of the Reed Mountain are well seen in the cave between the block ½ mile north of Table Head and the north end of Table Head. Here near the base are globidymograpus in li, and a few small Hornitoma likeforms. The contact between these beds and the Chazy is well exposed in a low cliff running out into the sea, very bedded Below is the unmistakable Reed Mountain magnesian li, and on its inner surface with irregularities of one foot depth comes in at once the thinly dural li. of the Chazy. A few higher appear characteristic Chazy mids. This relation of the two formations is done just like
