Discoveries in Australia Volume II Part 15

The highest hill on the south-west point, measuring 42 feet, received the name of Record Hill, from our leaving a paper in a bottle, giving an account of our cruise. A contiguous reef stretched out from the west side of the island for the distance of a mile, beyond which was the open sea.

This reef extended two miles and a half to the North-North-West and four miles and a half to the southward. Our observations were made on a sandhill 36 feet high, immediately over the bay, which they placed in lat.i.tude 32 degrees 18 minutes 5 seconds South longitude 2 degrees 9 minutes West from Swan River.

LEAVE HOUTMAN'S ABROLHOS.

May 23.

From Record Hill we had perceived that the sea was quite clear to the north and west beyond the reef, and being satisfied that we had reached the extremity of Houtman's Abrolhos,* we weighed in the morning, and pa.s.sed about a mile and a half from the reef to the north of the island in 26 fathoms; and hauling up South-South-West, along the western side of the reefs, gradually deepened the water to 42 fathoms over a rocky ground, Record Hill bearing North 70 degrees East six miles and a half.

We then had no bottom with 50 and 60 fathoms until noon, when we had 122 fathoms, sand and coral; Record Hill then bearing North 52 degrees East eleven miles and a half, just barely visible from the p.o.o.p. It is singular that we should have had bottom at that distance from the group, whereas, when we had not proceeded half so far from the southern portion we had no bottom with 200 fathoms.

(*Footnote. Their extent in lat.i.tude therefore nearly corresponded with the old chart; and the apparent confusion in the shape given them, no doubt arose from their extremes only having been seen and then extended towards each other.)

To ascertain if there were any more reefs to the westward, we now steered West-South-West, sounding occasionally with 200 and 220 fathoms unsuccessfully.

After running thirty-two miles without seeing any indication of further dangers, of which, moreover, the long ocean swell rolling in convinced us, we steered to the northward.

GENERAL OBSERVATIONS.

It may be proper to conclude our account of Houtman's Abrolhos with a few general remarks. They form three groups instead of one, as was formerly supposed; Pelsart Group being separated from Easter Group by a channel, the least width of which is four miles, whilst the middle pa.s.sage between the latter and the Northern Group is six miles wide. The Abrolhos extend in a North-North-West direction forty-eight miles, diminishing in breadth towards the north; the greatest width of Easter and Pelsart Groups being twelve miles in a West-South-West direction. In Easter Group the outer reefs are most distant from the islands, being there four miles from the nearest, which is Rat Island. In the Northern Group the islands are more detached than in the others, and North Island is separated from them by a distance of ten miles.

We have already alluded to the regularity and sameness in the soundings in these groups, and between them and the main, clearly showing that they are not connected with each other, but rest on the outer extremity of a level or bank, stretching out from the main, and having a slight southerly inclination, the depth (29 fathoms) between the southern group and the coast being greater by four fathoms than between the coast and the northern group. On either side of the Abrolhos, at the same distance from land, the depth is more than 100 fathoms. The general nature of the bottom, in the quiet places between the reefs, is a fine grey sandy mud or marl, but in more exposed situations this is not so compact, whilst broken sh.e.l.ls are more abundant. This bottom bears a striking resemblance to that within the Great Barrier Reefs.

After leaving the Abrolhos, as I have narrated, our progress to the northward was unusually slow, and between the parallels of 26 degrees 50 minutes South and 25 degrees 40 minutes South we again got into soundings varying from 187 to 81 fathoms, fine grey sand. At the greatest depth the ship was forty miles from the land, and twenty miles at the least, which was off Dirk Hartog's Island, at the south point of Sharks Bay. In pa.s.sing round the north-west extremity of the continent we delayed, again endeavouring to get sight of Ritchie's Reef; but, on this occasion, as on our pa.s.sage from the Victoria to Swan River, it was not seen, and as no bottom was obtained with 200 and 240 fathoms in its a.s.signed position on the chart, it must either have a very different one or does not exist.

PROCEED TO THE COAST.

The part of the North-west coast that had not been seen by Captain King, commencing a short distance to the east of Depuch Island, it was resolved that our survey of that part should begin there, and on the 9th of June the Beagle reached an anchorage off a sandy bay on the north-east side of that island. As we drew near our progress was impeded by a fierce south-east breeze during the forenoons, which we found to prevail during our stay, being stronger at the full and change of the moon. Although coming directly from the land they quite made us shiver, reducing the temperature on one occasion to 59 degrees. These winds began about daylight at south, gradually veering and drawing round to the eastward as the day advanced, and subsiding again as rapidly after noon, leaving the evening and night generally calm.

SEARCH FOR WATER.

A search was immediately made for the stream of fresh water reported to have been found by the French, in Freycinet's voyage, on Depuch Island.

As our stock was now very much reduced, and as our stay on the coast depended on the supply we could procure here, we were greatly concerned to find that our examination was in vain. Everything appeared parched up; wells were forthwith commenced, and we dug as many as eight, but at the depth of twenty-one feet the water that poured into them was salt.

Fortunately Mr. Bynoe found a reservoir of water in the main valley leading up from the north end of the sandy beach, and about a mile from the sea. From this we got about six tons of tolerable water, although the labour of carrying it on the men's shoulders in seven-gallon barecas was very great, the only road lying through the valley, which, as may be inferred from the rounded stones it is strewed with, sometimes conveys a torrent to the sea. Large columnar blocks of the greenstone of which the island is composed, present, as the sun falls on their iron rusty surface, an appearance as if the sides of the valley were lined with red warriors. The section presented to our view, by the deepest well we sank at the mouth of this valley, consisted of a light kind of mould for six feet, then a layer of sand and sh.e.l.ls of the same depth, resting on a coa.r.s.e soft kind of reddish sandstone.

FORESTIER GROUP.

Depuch is the centre of a string of islands which bears the name of Forestier Group, fronting the coast at the distance of from one to three miles. It is much larger than the others, being about eight miles in circ.u.mference, and reaching an elevation of 514 feet; whereas the smaller islands, some of which are thickly covered with brushwood and coa.r.s.e gra.s.s, are none of them above 50 feet high. They are of a formation totally different, being of a very coa.r.s.e gritty yellow sandstone, in many places quite honeycombed, with some low sandhills superimposed.

DEPUCH ISLAND.

Although Depuch Island is one vast pile of reddish-coloured blocks, scattered about in the greatest possible confusion, sometimes resembling basaltic columns, its outline from seaward appears even. In the valleys, and on some of the more level spots near the summit, there are occasionally slight layers of soil, affording nourishment to a coa.r.s.e gra.s.s, a few bushes, and several stunted eucalypti; but on the whole the vegetation of the island is extremely scanty. From the highest point we had a view over the main, extending inland for a great distance. It appeared to be flat, with the exception of some isolated rocky hills, of a formation similar to that of Depuch, from 200 to 500 feet in height, and about six miles from the sh.o.r.e. We could also see at a distance of twenty-eight miles a very remarkable pyramidal hill, surmounted by a tower-like piece of rock, bearing from our position South 30 degrees West. From the white appearance of many large patches of the level country, we inferred that they were covered with a salt efflorescence; and it is probable that a very great portion of it is occasionally flooded, being cut up by a number of creeks, which must overflow at spring tides, especially when they occur simultaneously with the north-west winds that prevail on this coast during the monsoon.

This group of islands is so connected with the main by extensive sandbanks, that at low-water it is possible to walk across to them; and of this facility the natives no doubt avail themselves to procure turtle.

It appears indeed to be only on such occasions that they can visit Forestier Group, as we saw no traces of rafts on this portion of the coast. Depuch Island would seem to be their favourite resort; and we found several of their huts still standing. They were constructed of boughs and twigs fixed in the ground, and joined overhead in a circular shape. Over this was thrown a loose matting of twisted gra.s.s.

NATIVE DRAWINGS.

The natives are doubtless attracted to the place partly by the reservoirs of water they find among the rocks after rain, partly that they may enjoy the pleasure of delineating the various objects that attract their attention, on the smooth surface of the rocks. This they do by removing the hard red outer coating, and baring to view the natural colour of the greenstone, according to the outline they have traced. Much ability is displayed in many of these representations, the subjects of which could be discovered at a glance. The number of specimens was immense, so that the natives must have been in the habit of amusing themselves in this innocent manner for a long period of time. I could not help reflecting, as I examined with interest the various objects represented*--the human figures, the animals, the birds, the weapons, the domestic implements, the scenes of savage life--on the curious frame of mind that could induce these uncultivated people to repair, perhaps at stated seasons of the year, to this lonely picture gallery, surrounded by the ocean-wave, to admire and add to the productions of their forefathers. No doubt they expended on their works of art as much patience and labour and enthusiasm as ever was exhibited by a Raphael or a Michael Angelo in adorning the walls of St. Peter or the Vatican; and perhaps the admiration and applause of their fellow countrymen imparted as much pleasure to their minds as the patronage of popes and princes, and the laudation of the civilized world, to the great masters of Italy. There is in the human mind an irresistible tendency to indulge in a sort of minor creation--to tread humbly in the footsteps of the Maker--to reproduce the images that revolve within it, and to form, from its own ideas, a mimic representation of the actual world. This is the source of all art and all poetry; of every thing, in fact, which tends to adorn and refine our nature. It is this uncontrollable desire to work on and fashion the rough materials that lie under our hands that gives the first impulse to civilization, and impels us onward in the progress of improvement. And wherever we discern the faintest indication that such a principle is at work, there we may securely hope that development will ultimately take place. Until we find a nation which has never attempted to emerge from the circle of its mere animal wants--which has never exhibited the least inclination to develop the most ordinary arts--which not only rejects clothing, but is absolutely indifferent to ornament--which leaves its weapons uncarved, its skin unpainted, free from tattoo, we must not despair of the general efficacy of civilization. These savages of Australia, as we call them, who have adorned the rocks of Depuch Island with their drawings, have in one thing proved themselves superior to the Egyptian and the Etruscan, whose works have elicited so much admiration and afforded food to so many speculations--namely, there is not in them to be observed the slightest trace of indecency.

(*Footnote. See the accompanying lithographic impression of the copies made by Captain Wickham of the native drawings on Depuch Island.)

During our stay we did not see any of the natives on the island; but on the main several of them were observed, though they would not allow us to communicate, moving off as soon as any attempt was made to get near them in the boats. On one occasion, when Mr. Fitzmaurice, in a whaleboat, was examining a part of the coast to the eastward of Depuch Island, he entered a creek, which soon, however, became too confined by the mud-banks for them to use the oars.

HOSTILITY OP THE NATIVES.

While in this position a shout attracted his attention, and he perceived a party of natives, armed with spears approaching the boat, with evident hostile designs. They of course naturally looked upon us as intruders; and as the point was not worth contesting, the creek being of no importance, Mr. Fitzmaurice thought it better to withdraw, rather than run the risk of a collision that could have led to no beneficial results.

TOM'S TERROR OF THEM.

The native youth we had brought with us from Swan River did not at all approve of these excursions. He was generally taken, with a view of giving confidence to any of his wild countrymen who might be encountered; but he exhibited the greatest possible repugnance to this service. His terror for the northern men fully equalled that of Miago, from whom doubtless he had received the most terrific accounts. It was only by giving him a gun that he could be at all induced to go. He evidently felt himself more secure with European arms than with his own rude ones; and appeared to have learnt their superiority by experience, for he was a very fair shot. When I first asked him why he did not prefer his spear, his simple reply was, "Can't look out;" meaning that the northern men could not see the contents of a gun coming, whereas if a spear were hurled at them they could avoid it. His bravery was of much the same complexion as that of Miago; and he threatened magnanimously to inflict the most condign punishment on the fellows who opposed Mr. Fitzmaurice's landing. He had a strong impression that these northern people were of gigantic stature; and in the midst of the silent and gaping interest with which he listened to Mr. Fitzmaurice's account of his adventure, the words big fella often escaped from his lips; and he appeared quite satisfied when a.s.sured that his opinion was correct.

The agility this native exhibited in spearing fish was astonishing. In shallow water he would actually course the fish till he got them within spearing depth, when, although his prey darted past, he struck it with the most surprising precision. The quiet, splashless manner in which he ran through the water was really singular. When his spear required new pointing, the sole of his foot was turned up and the spear's head pared down upon it with a knife. When the latter was not to be procured the teeth were made use of; and I may here remark that the constant use which some savages make of their teeth may have much to do in producing the projecting jaw. It seems almost evident to common sense that the constant employment of the teeth must have a material effect in causing a change in the facial angle.

ANCHORAGE AT DEPUCH ISLAND.

We found the anchorage at Depuch Island to form a tolerable port, being protected from the north-east by one of the group, distant about three miles, from which a reef extends to the West-North-West, leaving the mouth of the harbour exposed only between North-West by North and West-North-West. Our observations placed the centre of the sandy beach on the north-east side of the island in lat.i.tude 20 degrees 37 minutes 47 seconds South and longitude 2 degrees 0 minutes 20 seconds West of Swan River, variation 2 degrees westerly; and the time of high-water, at the full and change, at half past ten, when the tide rose 15 feet, but only 5 during neaps.

NEW BIRD AND KANGAROO.

Although Depuch Island had been visited before, there still remained something quite new to reward the diligent search that was made after objects of natural history: namely, a small kind of kangaroo, a land bird, and a sh.e.l.l, a species of Helix. The bird was shot by Mr. Bynoe; it was a finch,* and beautifully marked with stripes of crimson down the breast, on a black ground with white spots; the throat, and a patch round the stump of the tail, were crimson. It is remarkable that all the beauty and brilliancy of colour in this bird is underneath, the back being of a common earthy brown.

(*Footnote. Named by Mr. Gould from this specimen, Emblema picta.)

The kangaroo I had myself the good fortune to knock over on the summit of the island; it was the only one shot during many an excursion made over that dreary heap of desolation, the metallic sound the rocks yielded to our step giving ample warning of our approach to their quick ears. The colours of this specimen, the prettiest we had seen, were a dark grey, with a large angular patch of white down the side, extending from the top of the shoulders nearly to the hips. Down the centre of the back, ran a streak of black, which was also the colour of the extremity of its slightly bushy tail. The face and belly were likewise darker than other parts of the body, and the feet were black and well cushioned, giving it a firm hold of the rocks over which it bounded with surprising agility, through it never ran very far, always popping into the cavities caused by the loose manner in which the blocks forming the island are thrown together.*

(*Footnote. Mr. Gould has figured an animal very like this I have described, as Petrogale lateralis, or the Stripe-Sided Rock Wallaby, from a specimen he some time afterwards got from Western Australia; but he has not noticed the beautiful kangaroo of Depuch Island.)

The specimen of the species of Helix I have above mentioned was found by Mr. Dring, one of our most successful collectors in that department. In the Appendix are figured some of the new sh.e.l.ls discovered during the voyage.

Leaving Depuch Island, we examined the coast to the eastward as far as the Turtle Isles, a distance of eighty-five miles, the first twenty-seven of which trended North 55 degrees East, and the remainder North 67 degrees East curving slightly inwards. As the French had obtained a distant view of this coast, it did not possess to us the interest of being a new portion of the continent.

EFFECTS OF MIRAGE.

Still the effect of the treacherous mirage, which has often deluded the way-worn thirsty traveller with the false appearance of water, raised many parts of the interior that had not before met the eye of an European. These presented a very level outline. The interior was, for a great distance, a vast plain, so low that we could scarcely see it from the ship's masthead over the sandhills, which did not exceed the height of 40 feet. Six or seven miles from the Turtle Isles this extensive level was interrupted by the presence of a group of hills, from 200 to 300 feet in elevation, apparently of the same character as the heights behind Depuch Island. As seen through the medium of mirage, they often had a most curious appearance: high continuous ranges, changing again to lofty islands, danced in the tremulous air. I should remark that when the land was subject to this distortion, it was always during the forenoon, and on those days the winds were invariably light.

APPEARANCE OF THE COAST.

The sh.o.r.e, for nearly fifteen miles from Depuch Island is very low, lined with mangroves, and intersected by creeks, which at high-water, when the tide rises sometimes 18 feet, are of some magnitude, and inundate much of the low land, leaving large portions of it whitened by a salt incrustation. Beyond, as far as the Turtle Isles, the coast is fronted with a ridge of sandhills, scantily covered with vegetation (the highest, as I have already said, rarely exceeding an elevation of 40 feet) forming a barrier between the sea and the low lands behind, which, from the masthead, appeared to be thickly covered with small trees, and slightly raised from three to seven miles from the coast. Several of the natives showed themselves at a distance, and from the numerous fires, it appeared to be a well inhabited part of the continent. Still we saw no appearance of a stream of fresh water; and, though there were several creeks, the only opening of any consequence was forty-three miles from Depuch Island.

From its abounding with oysters we named it Oyster Inlet. Across the mouth of it lies an islet, just within the north-eastern end of which there was a sufficient depth for the Beagle. The formation of the island was a reddish porous sandstone. At a native fire-place I found a piece of quartz and a large pearl oyster-sh.e.l.l. The tide rose here 15 feet near full moon.

THE GEOGRAPHE SHOALS.

The only outlying dangers on this extent of coast were the Geographe Shoals, two rocky patches some distance from each other. The outer one was thirteen miles from the main, and bore North 22 degrees East twenty-three miles from Depuch Island.

TURTLE ISLANDS.

The sh.o.r.e fronting the north Turtle Island projects, leaving a s.p.a.ce of only ten miles between, of which, on account of the shoals, only a small portion lying near the island is navigable. Nearly opposite the latter is another opening, of some extent at high-water; but from the impediments that offered to our examining it, we named it Breaker Inlet. During spring tides it must carry a large body of water over the very low land it intersects.

The South Turtle Isle is a mere bank of sand and white coral; the northern is about half a mile across, of the same formation precisely as the low isles of Forestier Group. It is fronted on all sides with a coral reef extending off from a mile to a mile and a half, which dries at low-water, leaving an abrupt wall of from two to three feet at the outer edge, with pools between it and the island, in which several luckless turtles, who had deferred leaving until too late, were found. Though we only took what was required for our own consumption, the number that could have been here obtained was enormous.
