I spent the day collecting mainly on the eastern side of the island since till then the rocks are not approachable and are least common. The entering thickness, seen does not exceed five or six feet. Two feet of this overlie the Stromatoporos limestone and is a black bituminous shale limestone holding a Spirifer, Meristella, Pentamerus, Aceroularia and said a cup coral. Among many of the fossils of this gene are crushed. The limestone belong to the Stromatoporus limestone with an abundance of Aceroularia. The forms give the limestone a domed and concentric appearance. The domes are sometimes two or three feet high and twelve feet in diameter.
