There are good landings for boats in Simoda creek, and at the village of Kakizaki. A harbor-master and three pilots have been appointed; wood, water, fish, fowls, and eggs, also sweet potatoes and other vegetables may be procured from the authorities. It is necessary to supply them with casks to bring the water off. Latitude Centre island 34° 39′ 49″ N. Longitude ” ” 138° 57′ 50″ E. Variation 52′ westerly. High Water, F. and C 5 hours. Extreme rise of tide 5 ft. 7 in. Mean ” ” 3 ft. To make the foregoing directions more easily comprehended, they have been rendered as concise as possible, but to furnish further information to navigators bound to, or passing the port, the following additional remarks are appended:— The harbor of Simoda is near the southeastern extremity of the peninsula of Idzu, which terminates at the cape of that name. To the northward of the harbor, a high ridge intersects the peninsula, and south of this, all the way to the cape, it is broken by innumerable peaks of less elevation. The harbor bears S. W. by W. from Cape Sagami, at the entrance of Yedo bay, distant about 45 miles. Rock island is about 120 feet high, and a third of a mile in length, with precipitous shores and uneven outlines. It has a thick matting of grass, weeds, moss, &c., on the top. From the summit of this island overfalls were seen, bearing N. ½ W., distant a mile, or mile and a half. These may have been caused by a rock or reef. An attempt was made to find it, but the strong current and fresh wind prevented a satisfactory examination. The Japanese fishermen, however, deny the existence of any such danger. N. by W. from Rock island, distant 2 miles, are the Ukona rocks. These are two rocks, though they generally appear as one. The largest is about 70 feet high. Between these and Rock island, the current was found setting east-northeasterly, fully four miles an hour. Centre island bears from Rock island N. ½  E., distant 5½ miles, and from Ukona rocks N. by E. ½  E., distant 3½ miles. Buisako islet lies N. N. E. from Centre island. It is about 40 feet high, and covered with trees and shrubs. Should the buoy on Southampton rock be removed, the east end of Centre island on with the west end of Buisako, will clear the rock to the westward. Off the village of Susaki, and distant one third of a mile from the shore, is a ledge of rocks, upon which the surf is always breaking; give them a berth of two cables in passing. Approaching from the eastward, the harbor will not open until you get well inside of Cape Diamond.
