We had a fair wind during the night and sailed north-east, finding ourselves in the morning about twenty miles west of the extremity of Waigiou with a number of islands intervening. About ten o'clock we ran full on to a coral reef, which alarmed us a good deal, but luckily got safe off again. About two in the afternoon we reached an extensive coral reef, and were sailing close alongside of it, when the wind suddenly dropped, and we drifted on to it before we could get in our heavy mainsail, which we were obliged to let run down and fall partly overboard. We had much difficulty in getting off, but at last got into deep water again, though with reefs and islands all around us. At night we did not know what to do, as no one on board could tell where we were or what dangers might surround us, the only one of our crew who was acquainted with the coast of Waigiou having been. left on the island. We therefore took in all sail and allowed ourselves to drift, as we were some miles from the nearest land. A light breeze, however, sprang up, and about midnight we found ourselves again bumping over a coral reef. As it was very dark, and we knew nothing of our position, we could only guess how to get off again, and had there been a little more wind we might have been knocked to pieces. However, in about half an hour we did get off, and then thought it best to anchor on the edge of the reef till morning. Soon after daylight on the 7th, finding our prau had received no damage, we sailed on with uncertain winds and squalls, threading our way among islands and reefs, and guided only by a small map, which was very incorrect and quite useless, and by a general notion of the direction we ought to take. In the afternoon we found a tolerable anchorage under a small island and stayed for the night, and I shot a large fruit-pigeon new to me, which I have since named Carpophaga tumida. I also saw and shot at the rare white-headed kingfisher (Halcyon saurophaga), but did not kill it. The next morning we sailed on, and having a fair wind reached the shores of the large island of Waigiou. On rounding a point we again ran full on to a coral reef with our mainsail up, but luckily the wind had almost died away, and with a good deal of exertion we managed get safely off.
