(*Footnote. From the result of our soundings on the passage to the coast, it would appear that a ship in 60 or 70 fathoms would be about the same number of miles from the land between the latitude of 14 or 15 degrees South--quality of bottom, a greyish sand, which becomes coarser as the depth increases.) After midnight on the 3rd and 4th we had strong breezes of short duration from South-East, and although a hundred miles from the nearest land to windward, a fine kind of dust was found on the rigging, which, on examination by a microscope, proved to consist of sand and wood ashes. REACH THE NORTH-WEST COAST. We saw the land to the southward of Roebuck Bay on October 8th, and at noon passed four miles from Cape Bossut, which we found to be in latitude 18 degrees 42 minutes South and longitude 121 degrees 45 minutes East.* On the south side opened a bay two miles deep, with a small high-water inlet at its head. From thence we held a general South by West 1/2 West course, passing along the land at the distance of from three to four miles, in soundings of 5 and 6 fathoms, and at sunset anchored four miles from a low sandy coast, on which the sea broke heavily. Cape Joubert,** distant sixteen miles, was the last projection of any kind we passed. (*Footnote. The longitudes depend on the meridian of Coepang. which has been considered in 123 degrees 37 minutes 0 seconds East.) (**Footnote. In latitude 18 degrees 58 minutes South and longitude 121 degrees 42 minutes East. It is crested with bare white sand, and although only forty-five feet high is a remarkable headland on this low coast.) APPEARANCE OF NORTH-WEST COAST. From that headland commenced a low, wearisome, sandy shore, which we traced for sixty-five miles in a South-West by West direction, looking in vain for some change in its character. Nothing beyond the coast sand-dunes, sprinkled with vegetation, and only twenty feet high, could be seen from the masthead, although the ship was within three miles of the beach. This cheerless aspect was heightened by the total absence of native fires, a fact we had never before observed in such an extent of country, and truly significant of its want of fertility. Still, in our sight it possessed a greater charm than it may, probably, in that of others; as every fresh mile of coast that disclosed itself, rewarding our enterprise whilst it disappointed our expectations, was so much added to the domains of geography. That such an extent of the Australian continent should have been left to be added to the portion of the globe discovered by the Beagle was remarkable; and although day by day our hopes of accomplishing any important discovery declined, a certain degree of excitement was kept alive throughout.
