here Boring out again in the railway I found another Arthrofocus layer in the second cut west of Hudson shale Ain and here it is about 100' higher than the base of second the cut or 55 yards to the north. They are here as plen- tiful as in the quarry, could it probably be the same layers. This horizon is 550 feet above base. Saw one about 200 feet higher and then again at about 700 feet above the base. All in the second cut on railway. mountain Boring around the curve in the first great side highly inclined stripping one sees that the Charrang group is introducing more shale and some of the beds are barely a foot thick. Here too the conglomerates have chipped out about the sand- stones as coarse as before. I should judge that from 50 to 100 feet higher I again saw unmistakable Arthro- fycus. This is in the cut to the north of the semiphone port Boring south between 77 and 78 mile posts for Jerry city one sees yellowish and less often reddish shales with (1-3-4 feet) thick beds of sandstones. As one goes along the strike out around for the line is down. All of these beds I take to be in the transition to Clinton. At 77 mile post saw my first small horizon and one finds stratales Othermore.
