Kuro se, a small black rock, 25 feet high, lies S.W. by W. one mile from the south extreme of O sima, and S. by W. 4 cables from Mutsz-se. The north-east side of Kuro se is foul, there being a patch of 24 fathoms three-quarters of a cable from it; the west and south sides can be passed at a cable distance, in 16 fathoms.
Hoge sima, 14 miles W. S. from O'sima, is 200 yards long north and south, having over the south end a conspicuous peak, 200 feet high, which rises precipitously from the sea; over the northern point is a small peak connected to the southern portion of the rock by a perforated arch, which shows out prominently from the westward.
Yaburagi sima, 204 feet high, half a mile to the northward of O sima, is half a mile long east and west, and nearly half a mile broad, having at one cable from its west side a small cluster of rocks (Kai-ze), 70 feet high, and semi-circular in shape. Koro is a small island, a quarter of a mile north-eastward of Yaburogi sima, having on its west side cliffs 175 feet high. Between the north point of Koro and Ojika, a distance of 3 cables, are numerous dangers, which show at low water. Four cables to the eastward of Koro lies a small bare island 52 feet high.
Aka sima, 335 feet high, 22 miles west of Ojika, is three-quarters of a mile long east and west and 700 yards broad; the summit of this island rises perpendicularly from the sea on its south side, and over the south-west point are several small hummocks which show out prominently from the southward and westward. Off the north-west part of Aka sima are a few small rocks above water; vessels should not pass the north and east sides nearer than three cables, but the south and west sides can be passed in smooth water at one cable distance.
Madara sima, 407 feet high, and nearly a mile in extent, is separated from the west point of Ojika by a channel one cable wide, with 9 feet water. Near the west side of Madara sima is a small rock 20 feet high. The north and west sides of this island can be passed at 2 cables distance.
Hoage (Arch Rock), situated west 4 miles from Madara sima, consists of two remarkable pinnacle islets, 150 yards in extent, bearing from each other east and west; the western islet is 167 feet high, and the eastern 120 feet high, having a hole through it, visible only from the northward or southward.
Danger.—A rock, dry 5 feet at low water springs, with 5 to 11 fathoms round it, and on which the sea generally breaks, lies to the northward of Hoage, with the summit of Biriyo sima in line with the west extreme of Hoage, bearing S.W. S., distant from the latter 6 cables, and Aka sima west point S.E. by E. easterly. There is a depth of from 20 to 34 fathoms between this rock and Houge.
westward.
The high water mark of the west extreme of O sima in line with the west point of Aka sima, bearing S.E. 3 E., north-east of the danger; and the east extreme of Hira sima in line with the west end of Hoage, S.S.W., leads to the leads
Kura sima, 380 feet high, nearly 3 cables to the southward of Hoage, is almost square, and a quarter of a mile in In the channel between Kura sima and Hoage there are no dangers, depths of 17 to 20 fathoms being found in the
extent.
centre.
Biriyo sima, S.W. W., 14 miles from Kura sima, may be known by being the highest island to the south-westward of Ojika; it has two peaks, the northern 470 feet and the southern 445 feet high. "Biriyo sima is nearly half a mile long north and south, about a quarter of a mile broad on its north side, and half a mile on its south.
Hira sima, 167 feet high, situated 6 cables south of Biriyo sima, is nearly half a mile long east and west, and is the southernmost island in this locality. Off its south point there is a small rock 29 feet high, and 44 cables to the westward of the south end lies a rock 24 feet high; there are other rocks near the west point, and rocky ledges extend to the north- ward from its north side, a distance of 2 cables, with shoal water extending some distance to the northward of them. Close to the east point of Hira sima there is a depth of 5 fathoms; one cable to the southward of the rock off its south point, 22 fathoms; in the centre of the channel between Hira sima and the 24 feet rock to the westward, 12 fathoms. This rock is steep-to on its south side, but the soundings off its north and west ends are uneven, and a p. 24cables trom it.
Shiro-se, 105 eet high, 13 miles W. by S. from Ojika seto, is the Goto islands. Shiro-se is divided into two pinnacles, nearly the same height, and lies in a north-east end south-west direction.

portion of the high water mark,
Off the south side of this islet is a small rock, and off the north side are several rocks above water extending nearly one cable to the northward, with deep water beyond; the east and west sides of Shiro-se are steep-to, and can be passed at
one cable.
Hodge rock (Shaku shi), a rock awash at low water, with deep water around it, lies N. W., distant 44 cables from Shiro-se, the north peak of Nosaki sima in line with Hoage, bearing East, will lead 2 cables to the northward of Hodge
rock.
Korai-no-ze rock with 18 feet water, lies near the south-east edge of a rocky bank; this bank extending N.W. by N., three quarters of a mile, with a breadth of 4 cables, has from 5 to 10 fathoms. At 3 cables southward of the rock the depth is 20 fathoms; and at half a mile from the depth of 5 fathoms on the northern edge of the bank, there is 38 fathoms.
Clearing marks.-North point of Biriyo-sima in line with the north peak of Nosaki-sima bearing E. & N., leads northward of Korai-no-ze. South point of Hira-sima in line with the north peak of Nosaki-sima bearing E. by N. † N., leads southward of Korai-no-ze.
Nakadori sima is 21 miles long between Sawo saki the south and Tsua saki the north extreme. The coast line of Nakadori sima, the greater part of which has not yet been surveyed, is deeply indented with bays.
The northern part of this island for a distance of 6 miles to the southward of Tsua saki is very narrow, having high hills and mountains which rise abruptly on both sides. O-mitzu yama, a flat peak 1,446 feet high, is the summit of Nakadori sima; Yabokura yama, 1,197 feet high, lies 24 miles to the northward of O-mitzu yama, thence to the northward the hills are much lower, the ridge over Tsua saki being about 250 feet high.
Shimomu sima, 275 feet high, lying S.S.E. 13 miles from the north end of Nakadori sima, and one mile from the eastern shore, is nearly half a mile long north and south, and 400 yards broad.
Tan-ji, 91 feet high, a remarkable conical shaped islet, lying half a mile N.E. by N. from Süimomu sima, is steep-to except on the west side, from which rocks extend nearly one cable.
The north-east peak of Ojika, open one-third the breadth of the channel between Nosaki sima and Nakadori, bearing N.N.W. W., will lead through the deepest water between Tan-ji and Shimomu sima.
Kamigashi is a rock 53 feet high and steep-to, lying 84 cables off the east side of Nakadori sima, and a little over 3 miles to the southward of Shimomu sima, having off its north end a small rock 2 feet high.
yama.
Ikatchi is a rock 15 feet high, situated 2 cables from the western shore of Nakadori, about one mile north of O-mitzu
Vessels must not pass eastward of Ikatchi.
Tsubo gashi, 10 feet high, with 12 to 20 fathoms round it at half a cable distance, lies W. by S. S. about one mile from Ikatchi, and 14 miles to the northward of the entrance to Nama ura.
Nama ura.—This bay, situated immediately to the southward of O-mitzu yama, may be recognised by a conical rock 813 feet high, which forms the south entrance point of the bay. Nama ura is 2 miles deep and half a mile wide, with an even depth of about 16 fathoms; from the north-east side of the entrance shelving rocks, which dry at low water, extend 1 cables in a south-westerly direction, with shoal water nearly 2 cables to the south-westward; Cope rock, the south-west entrance point, is steep-to, and has a depth of 16 fathoms about three-quarters of a cable to the north-eastward.
