[EAST COAST. BARRIER REEFS.]
The tide prevented us from weathering the islands till three in the afternoon; we then passed between No. 4 and some rocks lying two miles to the north-east, with 33 fathoms water. During the night we tacked every two hours, working to the eastward, in from 30 to 36 fathoms; and at daylight [TUESDAY 5 OCTOBER 1802], my station on the eastern isle No. 4 bore N. 89° W., four leagues. Nothing was seen in the offing, but in stretching to the N. N. E, reefs were discovered from the mast head a little before noon; and after the observation for the latitude was taken, I set one bearing East to E. by S., two leagues, and another N. 14° W. to 29° E., four or five miles. Our situation was in 21° 15 2/3' south, and longitude from the bearing of the Pine Peak, 150° 34' east.
These reefs were not exactly those seen by Mr. Campbell; but they are probably not more than five or six leagues to the north-westward of them, and form part of the same barrier to the coast. In standing on between the two reefs above set, others, or parts of the same, came in sight ahead; upon which I shortened sail to the three top sails, desired the Lady Nelson to take the lead, and bore away north-westward along the inner side of the northern reef. In an hour we had passed its west end; but another reef came in sight, and for a time obliged us to steer W. by S. At four o'clock we ran northward again, following the direction of the reef on its lee side; and at six anchored in 27 fathoms, coarse sand, in the following situation:
Latitude observed from the moon., 21° 4' S.
Longitude from bearings, 150 19 E.
Nearest part of the reef, dist. 2½ miles, E. ½ S.
A smaller reef, distant 3 miles, N. W. ½ N.
Percy Isles, Pine Peak of No. 3, S. 9 0 W.
Cumberland Island marked 'k', W. 6 0 N.
The reefs were not dry in any part, with the exception of some small black lumps, which at a distance resembled the round heads of negroes; the sea broke upon the edges, but within side the water was smooth, and of a light green colour. A further description of these dangers is unnecessary, since their forms and relative positions, so far as they could be ascertained, will be best learned from the chart.
Until midnight, five hours after the moon had passed the meridian, a tide came from S. by E., half a mile per hour. The ship then tended to the N. E. by E.; and this tide, whose rate was one mile, appearing to be the flood, led me to suppose there might be an open sea in that direction. In the morning [WEDNESDAY 6 OCTOBER 1802], I sent a boat to lieutenant Murray with instructions for his guidance in case of separation; and appointed him Murray's Islands in Torres' Strait, discovered by captain Edwards in 1791, for the first rendezvous; cautioning him to be strictly on his guard against the treachery of the natives.
We weighed at seven o'clock, and steered N. N. E., close to the wind; at ten, reefs came in sight, extending from W. by N., to N. by E. ½ E., which we weathered one mile, having 35 fathoms water. Our situation at noon was in latitude 20° 45' 40", from observations to the north and south, and the longitude by time keeper 150° 28'; the east end of the great reef to leeward bore S. W. ½ W. two miles, and it extended in patches to N. 16° W., where, at the distance of two leagues, was either a dry white sand or high breakers but which could not be discerned from the reflection of the sun. Nothing was seen to the north-east, and we now lay up in that direction; but at one o'clock there was a small reef bearing N. ½ E.; and at three, a larger one extended from N. by W. ½ W. to E. N. E., and on the outside of it were such high breakers, that nothing less than the unobstructed waves of the ocean could produce them. We stood on for this reef, until four; and being then one mile off, tacked to the southward, having 33 fathoms, nearly the same depth as before.
The larbord tack was continued to six o'clock, at which time we anchored in 32 fathoms, white sand, shells, and pieces of coral, having neither reef nor danger of any kind in sight; but the smoothness of the water left no doubt of many lying to windward. From the high breakers seen in the afternoon, however, hopes were entertained of soon clearing the reefs; for by this time I was weary of them, not only from the danger to which the vessels were thereby exposed, but from fear of the contrary monsoon setting in upon the North Coast, before we should get into the Gulph of Carpentaria.
At this anchorage, the tide came from between S. W. by S. and W. by S., till midnight; and at two in the morning [THURSDAY 7 OCTOBER 1802] the ship rode north, and afterwards N. E. by E., to the flood; which seemed to imply two openings in the reefs, and one of them near the high breakers. The depth of water changed from 35 to 32 fathoms, in the night; but a part of the difference might arise from irregularities in the bottom.
We got under way at daybreak, and stretched south-east to gain the wind; at nine, a reef was passed on each beam; and at noon, when we tacked to the northward in 20° 58' south and 150° 48' east, there were five others, distant from two to five miles, bearing from S. 20° W., round by the east and north to N. 25° W.; but apparently with passages between most of them. Upon these reefs were more of the dry, black lumps, called negro heads, than had been seen before; but they were so much alike as to be of no use in distinguishing one reef from another; and at high water, nearly the whole were covered.
