Satisfied that no inland communication could be expected from Roebuck Bay, we weighed in the early part of the morning, and stood away to the northward.

APPEARANCE OF THE COUNTRY.

Roebuck Bay, so named to commemorate the name of Dampier's ship, is about sixteen miles across: the southern shores are low, and extensive sandbanks and mud flats are bared at low-water. Near the North-East point of the bottom of this bay, is a curious range of low cliffs, from twenty to thirty feet high, and strongly tinged with red, in such a manner as to suggest that they must be highly impregnated with oxide of iron. In the neighbourhood of these cliffs the country had a more fertile, or rather a less desolate appearance, stretching out into extensive plains, lightly timbered with various trees of the genus Eucalypti, while, on the south shore of the bay, the mangroves were numerous.

Towards the afternoon we discovered a small inlet, being then about 30 miles from our former anchorage in Roebuck Bay. We steered directly for it, and when within half a mile of its mouth, we had, at high-water, six fathoms. From the masthead I could trace distinctly the course of this inlet, which at this state of the tide appeared to be of great extent; but the bar which locked its mouth, and over which the sea was breaking very heavily, rendered it impossible to take a boat across without evident risk, by which no real good would be obtained, as the rise and fall of the tide, eighteen feet, on this low coast, was more than sufficient to account for the imposing, though deceptive appearance of this opening. From the main-top-gallant yard I was enabled to take an almost bird's-eye view of the level country stretched apparently at my feet. The shore, like the south side of Roebuck Bay, was fringed with mangroves, while to the North-North-East lay an extensive plain, over which the water seemed, at certain seasons of the year, to flow. The country around, for miles, wore the appearance of an interminable and boundless plain, with an almost imperceptible landward elevation, and thickly wooded with stunted trees.

In sailing along this part of the coast we found several inaccuracies in Captain King's chart, doubtless owing to the distant view with which he was compelled to content himself, and to the unfavourable state of the weather against which he had to contend. I was on deck nearly, indeed, the whole of the night, baffled by flying clouds in my attempts to fix our latitude by the stars: at length, however, I succeeded in ascertaining it to be 17 degrees 40 minutes South.

January 23.

The morning was fine, but the wind we had experienced the preceding night caused a rather heavy swell, which rendered the attempt to enter this inlet an impracticable task; however, it was tried. We found between the ship and the shore six, four, and two fathoms, but as the mouth of the inlet was filled with breakers, apparently on a bar extending out half a mile, I was fully convinced that further perseverance would only amount to waste of time and needless risk, and therefore, after taking a few angles to fix the position of the boat, we returned on board. It appeared at low-water to be nearly dry, and then only amounted to a collection of mud and sandbanks. The examination quite satisfied me that it partook of the same character as the one already spoken of as seen yesterday, and that they are alike useless.

We were soon underway, and standing towards, or rather along, the shore; and as the day advanced, the wind drew more to the westward, a common occurrence, enabling us to lay along the shore, North 1/2 East. By four P.M., we were within two miles of it, in nine fathoms.

The coast here is fronted with a range of sandhills, some of which are topped with verdure: several low black rocky points extend for some distance from the flat sandy beach into the sea. I have no hesitation in saying, that this is a kind of black sandstone, often found at the bases of most cliffy points, and probably coloured by the chemical action of the saltwater. The sandhills, which form the coastline, do not appear to extend more than a mile inland. Beyond, the country appeared to subside into the same dull level which is the characteristic feature of what we have yet seen of this coast, thickly studded with timber of a much finer growth than the stunted productions of Roebuck Bay. Behind the cliffy parts of the coast the land assumed a more fertile appearance; and this seemed an almost invariable law in the natural history of this new world.
