A far hundred feet over of Dover may be seen intraformational conglomerates and this time in the Trenton about 35 foot below the Etica. Its within more or less than a churning of the sea bottom. These occur at two levels. There are two in this part of the Trenton beside the marine layer or bredden bed, of the Etica. The "bredden bed" shows once in the first quarry to the east of the Dover station. Here photo'd of. It lies in the center of the picture and is away at one specially where places the whole bed is channeled. The thickness varies from me for to about 30 inches. The picture takes in the thicker part. This same layer is again in the next western quarry. But the Etica shows no more channel bottoms. The chief fossils of the Trenton are the Byggers, of bivalves one sees my Odmanella testudinaria Pleurotambula sericea, Refinosguira alternata as Jysopria clemonia, Maenus pagents are everywhere and rare one of Calymene. Clino- donta also are common.
