laid down under the influence of standing water. Twenty feet above the coal gang #4 of Logan is a zone [illegible] of muddy sandstone interbedded with shales. The sandstone are thin semi-cervicing. Proof that the water depth had again been filled in. Twenty feet of depth had been filled in with sand and coal and coal muds. Apparently above coal gang #4 comes in a thick zone of sandstone, about 25 feet thick. It is irregularly bedded flaglike, channeled below on the dark cantracoccus shales, and channeled within the mass, great holes ten feet deep filled of cryst red sandy shales. Above is grit beds of shales, red and green below the main coal. The sandstone is evidently the inflowing in a storm followed by grating land conditions. Looking at the various thin zones one is struck by the regularity of the bedding where the coal is present. The adjoining sandstones are then, regular in thickness from one end of the cliff to the other. This is the condition or lay as the shales are cantracoccus but other thick sand- stones occur these are usually crudely semi bedded, cut into the shales below (= channel), or cut into their own bed of sandstone and allow the red shales above to deposit crusty sand in those hollows in a very irregular way. Where the coals are absent there the shales are a light red in color alternating with some green shales.
