Geology; Geology, Stratigraphic; Paleontology; Geology, Economic; Géologie; Géologie stratigraphique; Paléontologie; Géologie économique. (u) Natural ilce. (b) Enlarged. (e) Apex enlarged. (d) Sculpture; magnified. In the section of the South Joggins I have noticed the occurrence of l\tpa Vetusta in another bed 1217 feet below that above mentioned. It belongs to group 8 of the section, and is between coals 37 and 38 of Logan's sectional list. It is a layer of gray indurated clay, with a slightly nodular structure, and in some places becoming black and carbonaceous, and containing leaflets of ferns, Tric/onocarpa, etc. The shells occur very abundantly in a thickness of about two inches. They have been imbedded entire; but most of them have been crushed and flattened by pressure. They occur in all stages of growth; the young being, as is always the case in such shells, very different in general form from the adults. This bed is evidently a layer of mud deposited in a pond or creek, or at the month of a small stream in shallow water. In modern swamps multitudes of shells occur in such places; and it is remarkable that in this case land shells should alone be found, without any trace of aquatic molluscs. The shells which occur in this bed are filled with the surrounding sediment. Those which occur in the erect Siffillarice, on the other hand, except when they are crushed and flattened, are filled with a deposit of brown calc-spar. I infer from this that the latter, when buried, contained 'he animals, and consequently that these lived or sheltered themselves in the hollow trees, as is the habit of many modem land Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Dawson, J.
