At four o'clock in the morning we weighed, and with a gentle breeze at south made sail out of the bay. In standing out, our soundings were from five to fifteen fathom; and at day-light, when we were in the greatest depth, and abreast of the north head of the bay, we discovered breakers stretching out from it N.N.E. between two and three miles, with a rock at the outermost point of them just above water. While we were passing these rocks, at the distance of about half a mile, we had from fifteen to twenty fathom; and as soon as we had passed them, we hauled along shore W.N.W. for the farthest land we had in sight. At noon, our latitude, by observation, was 23° 52' S.; the north part of Bustard Bay bore S. 62 E. distant ten miles; and the northermost land in sight N. 60 W.; the longitude was 208° 37', and our distance from the nearest shore six miles, with fourteen fathom water. Till five in the afternoon it was calm, but afterwards we steered before the wind N.W. as the land lay till ten at night, and then brought-to, having had all along fourteen and fifteen fathom. At five in the morning we made sail; and at day-light the northermost point of the main bore N. 70 W. Soon after we saw more land, making like islands, and bearing N.W. by N. At nine, we were abreast of the point, at the distance of one mile, with fourteen fathom water. This point I found to lie directly under the tropic of Capricorn; and for that reason I called it _Cape Capricorn_: Its longitude is 208° 58' W. It is of a considerable height, looks white and barren, and may be known by some islands which lie to the N.W. of it, and some small rocks at the distance of about a league S.E. On the west side of the cape there appeared to be a lagoon, and on the two spits which formed the entrance we saw an incredible number of the large birds that resemble a pelican. The northermost land now in sight bore from Cape Capricorn N. 24 W. and appeared to be an island; but the main land trended W. by N. 1/2 N. which course we steered, having from fifteen to six fathom, and from six to nine, with a hard sandy bottom. At noon, on latitude, by observation, was 23° 24' S.; Cape Capricorn bore S. 60 E. distant two leagues; and a small island N. by E. two miles: In this situation we had nine fathom, being about four miles from the main, which, next the sea, is low and sandy, except the points which are high and rocky. The country inland is hilly, but by no means of a pleasing aspect. We continued to stand to the N.W., till four o'clock in the afternoon, when it fell calm; and we soon after anchored in twelve fathom, having the main land and islands in a manner all round us, and Cape Capricorn bearing S. 54 E. distant four leagues. In the night, we found the tide rise and fall near seven feet; and the flood to set to the westward, and the ebb to the eastward, which is just contrary to what we found when we were at anchor to the eastward of Bustard Bay.
