High water took place in St. George's Basin at twenty minutes after twelve o'clock: the tide rose twenty-four feet. HANOVER BAY is a very convenient port, about five miles deep, but exposed from the North-North-West; the anchorage is, however, so good, that no danger need be apprehended. At the bottom of the bay there is a deep chasm in the land, yielding a fresh-water stream; beyond this the bay terminates in a shoal basin. In the offing are several rocky islets, particularly one, a high rock, which is very remarkable. A little to the north-east of the river is a sandy beach, the situation of which is in latitude 15 degrees 18 minutes 21 seconds, and longitude 124 degrees 46 minutes 50 seconds. HIGH BLUFF, the extremity of the promontory separating Hanover Bay from Port George the Fourth, speaks for itself. It is in latitude 15 degrees 14 minutes 40 seconds, and longitude 124 degrees 41 minutes 35 seconds. Between High Bluff and Point Adieu, in latitude 15 degrees 14 minutes 10 seconds, and longitude 124 degrees 34 minutes 45 seconds, is PORT GEORGE THE FOURTH, having midway in its entrance a high island nearly two miles long; and to the southward, in the centre of the port, a high rocky islet, the LUMP, the summit of which is situated in latitude 15 degrees 18 minutes 30 seconds, and longitude 124 degrees 37 minutes 50 seconds. The western side of the port is an extensive island, AUGUSTUS ISLAND, eleven miles long; it is high and rocky, and has several bays on its eastern side. The port affords very good anchorage, particularly between Entrance Island and the Lump, in nine fathoms, mud; but there is also very good anchorage with the Lump bearing west, in ten fathoms, mud. Port George the Fourth terminates in a strait, ROGER'S STRAIT, communicating with Camden Bay. The best entrance to the port is on the eastern side of Entrance Island; for the opposite, although practicable and sufficiently deep for the largest ships, is narrow, and must be buoyed before it can be used. POINT ADIEU is the last land seen by us in 1820: it is the north-east end of Augustus Island, and is a rocky, bluff point. In the offing, at the distance of three miles, there is a considerable range of reefs, that extend from the peaked island of Jackson's Isles; and more to the north-west is another group of rocky islands.
