"As far as observed today the Calamites, ostracods and Spirinite are in greatest profusion in the carbonaceous and clay shales and are absent in the sandstones, red and green shales. This evidence seems to prove that the coral swamps are under the influence of the sea, are salt water marshes on which the tidal waters are constant but not deep. It will probably turn out that all of these forms are directly of marine origin being forms that live in brackish or even in almost fresh waters. In one piece of very impure sandstone near the coral marl at Joggins Mines we counted over 20 upright Calamites varying in diameter from 1 to 2 inches and in length from 4 to 18 inches. Of upright trees we saw throughout division of about half a dozen. The last one is just a little to the north of the coral marl at Joggins Mines. Broad coral plants are remarkably scarce along the shore. The nearest of all are the Ferns and or far there seem but 2 species. The leaves of Cordaites are very common in the sandstones. In the sandstones we often see streaks of coal from 1/8 to 3/8 thick and from 2 to 4 feet long. These are always fine bituminous coals and must be the
