From this point a nar- row peninsula, half a mile wide and two and a half miles long, extends in a southwest direction from the main island. The island is of vol- canic origin, and consists of a cluster of flattened cones. The central cones of the island have an elevation of from two to three hundred feet, and a diameter of from half a mile to one mile and a half.
. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology. 90 BULLETIN OF THE Fig. Diagram of St. Paul's Island: a, harbor and native village; b, sea-lion rookery a point one third its length from the west end. From this point a nar- row peninsula, half a mile wide and two and a half miles long, extends in a southwest direction from the main island. The island is of vol- canic origin, and consists of a cluster of flattened cones. The central cones of the island have an elevation of from two to three hundred feet, and a diameter of from half a mile to one mile and a half. Those on the outside, which form the shore line, are much smaller, they being only from one eighth to half a mile in diameter, and from fifty to sixty feet in height. Their bases touch those of the central higher cones. Between the chains of cones are narrow valleys, raised but little above the sea level. The border cones are composed entirely of clinkstone, and their surfaces appear to have undergone no change other than that resulting from the original Assuring, and the subsequent action of frost. Where these cones extend into the water they form rounded points with gently sloping shores. There is a belt of loose rocks, varying from five to forty rods in width, between the base of the outer cones and the water. The coves formed between these points have shores of loose lava sand. The peninsula is formed by two of these cones, one of which is one half and the other two and a half miles distant from the main island, with which they have been recently connected by the deposition of loose sand thrown up by the action of the waves. The connecting.
