"The dark greenish and litter composed Laugan coarse sandstone.
The fate due is of lime and derived from the tituration of the limestone boulders. The blocks are about half under 6 inch long and less than 1 inch thick, the remainder are hoody broken pieces of them; they are range up as a rule not more than foot long, and with 8 sides to them. Most lie flat but the arrangement is irregularly zigzaged.
Then an upper zone very much like the lower one with a darker muddy-sandy paste. The thickness is about 8 feet. As before one of the limestone have Hazalents been considerable sandstone here in blocks up to 2 feet long. One light greenish sandy finely shale is 12 inches thick and 30 inches long.
At the top is a 3 foot bed of very fine limestone conglomerate in which the particles vary often one inch. At the scattering grain of coarse quartz sand and quartz pebbles up to 3/8 inch across.
Above come hard blue and green shales with thin lamina of dark green till black shales that we can see for 100 feet in thickness. The streak of the beds then does not show the effects.
