These islands are uninhabited, excepting when they are used as a place of resort by Malay pirates. They are six in number, and a rocky islet. As they are not laid down in any of our charts, they were named the “_Woodbury Group_,” in honour of my friend, the Honourable Levi Woodbury, the secretary of the navy. The northernmost island was called “_Geisinger_;” the most southern and eastern, “_Roberts_;” the centre one, between the two, “_Peacock_;” and that one lying farthest to the westward, and nearly in latitude of Roberts island, was named “_Boxer_:” the others were left unnamed. Their latitudes and longitudes, from three chronometers and a meridian observation, are as follows:--Two of them are about two miles long; one is in latitude 10° 16′ N., and longitude, 102° 43′ E., and the other in 10° 7′ and 103°. Two small islands and a rocky islet to the westward of them, lie in 10° 25′ and 103°. Two narrow islands, four or five miles in length, one in latitude 10° 19′ and 103° 12′ E., and the other in 10° 15′, and 103° 21′ E. On the sixteenth February, at noon, we were abreast of cape Liant and the islands in its vicinity; the latter are high and bold of approach. Their latitude and longitude are laid down in the charts too far to the southward and eastward. On the eighteenth we came to anchor in four fathoms of water, about ten miles from the mouth of the river Menam. The Ko Si-Chang islands bore as follows: The most southern and westward of the group, S. S. E. 3/4 E.; centre, S. E. 1/2 S. The mountain of Bang-pa-soe, on the main land, E. S. E. The entrance of the eastern or main branch of the Menam, and the easternmost land in sight, W. S. W. The land is very low, even with the water’s edge, and covered with trees; that at the entrance, on the starboard hand, is a little more elevated. On the nineteenth, the tide had fallen to nineteen. We weighed again, and stood a mile or two to the southward, and anchored in five fathoms. The latitude and longitude of the anchorage is in latitude 13° 26′ N., and longitude 100° 33′ E., as was ascertained by frequent lunar observations and by four chronometers. During the height of the river, when it is swollen by the periodical rains, sixteen feet of water may be found on the bar. At high spring tides, in the dry season, twelve to thirteen feet, and eight to nine in common tides. The above-named islands, by some navigators called the Dutch islands, possess a safe and beautiful harbour, formed between the principal, or Si-Chang island, and the next in magnitude, called Koh-kam. They are inhabited only by a few fishermen, and produce _some_ yams, bananas, capsicums, gourds, and cucumbers. A boat was despatched to them to obtain water, if possible, but it could not be found in sufficient quantities to furnish the ship. We had no other resource, but to send upward of forty miles for it, to Bang-kok, or else to take the brackish water of Packnam. Water, we were informed, could only be had at the
