Extract

The shore of the Menai Straits on the Carnarvonshire side, nearthe Suspension Bridge, is composed, as is well known, ofsandstones and shales belonging to the Carboniferous Series. Abouta quarter of a mile west of the bridge, however, some fissile, reddishand greenish shales appear on the foreshore, dipping at higherangles than usual. This might easily be ascribed to local disturbance, as a large fault is not far off, though the shale differs somewhat from that which is common in the Carboniferous rocks of the district, a fact which was noticed by Mr. G. H. Morton, who went with me along this part of the section.
