On the 20th April, symptoms of dysentery showed themselves amongst the crews. Two days later therefore the vessel set sail, and it took seven good days to get beyond the straits of Madura. They returned along the north coast of Lombok, and passed through the Allas Straits, between Lombok and Sumbawa. The first of these islands, from the foot of the mountains to the sea, presents the appearance of a green carpet, adorned with groups of trees of elegant appearance, and upon its coast there is no lack of good anchorage, whilst fresh water and wood are plentiful. On the other side, however, there are numerous peaks of barren aspect, rising from a lofty table-land, the approach to which is barred by a series of rugged and inaccessible islands, known as Lombok, the coral-beds and treacherous currents about which must be carefully avoided. Two stoppages at the villages of Baly and Peejow, with a view to taking in fresh provisions, enabled the officers to make a hydrographical chart of this part of the coast of Lombok. Upon leaving the strait, Bougainville made an unsuccessful search for Cloates Island. That he did not find it is not very wonderful, as during the last eight years many ships have passed over the spot assigned to it upon the maps. The "Triads," on the other hand, i.e. the rocks seen in 1777 by the Freudensberg Castle, are, in Captain King's opinion, the Montepello Islands, which correspond perfectly with the description of the Danes.

Bougainville had instructions to survey the neighbourhood of the Swan River, where the French Government hoped to find a place suitable for the reception of the wretches then huddled together in their convict-prisons; but the flag of England had just been unfurled on the shores of Nuyts and Leuwin, in King George's Sound, Géographe Bay, the little Leschenault inlet, and on the Swan River, so that there was no longer any reason for a new exploration. Everything in fact had combined to prevent it; the delays to which the expedition had been subjected had indeed been so serious that instead of arriving in these latitudes in April, they did not reach them until the middle of May, there the very heart of winter. Moreover, the coast offers no shelter, for so soon as the wind begins to blow, the waves swell tremendously, and the memory of the trials which the Géographe had undergone at the same season of the year was still fresh in the minds of the French. The Thetis and the Espérance were pursued by the bad weather as far as Hobart Town, the chief English station upon the coast of Tasmania, where the commander was very anxious to put in. He was, however, driven back by storms to Port Jackson, which is marked by a very handsome lighthouse, a granite tower seventy-six feet high, with a lantern lit by gas, visible at a distance of nine leagues.

Entrance to Sydney Bay.

Sir Thomas Brisbane, the governor, gave a cordial reception to the expedition, and at once took the necessary steps to furnish it with provisions. This was done by contract at low prices, and the greatest good faith was shown in carrying out all bargains. The sloop had to be run ashore to have its sheathing repaired, but this, with some work of less importance necessary to the Thetis, did not take long. The delay was also turned to account by the whole staff, who were greatly interested in the marvellous progress of this penal colony. While Bougainville was eagerly reading all the works which had as yet appeared upon New South Wales, the officers wandered about the town, and were struck dumb with amazement at the numberless public buildings erected by Governor Macquarie, such as the barracks, hospital, market, orphanages, almshouses for the aged and infirm, the prison, the fort, the churches, government-house, the fountains, the town gates, and last but not least, the government-stables, which are always at first sight taken for the palace itself. There was, however, a dark side to the picture. The main thoroughfares, though well-planned, were neither paved nor lighted, and were so unsafe at night, that several people had been seized and robbed in the very middle of George Street, the best quarter of Sydney. If the streets in the town were unsafe, those in the suburbs were still more so. Vagrant convicts overran the country in the form of bands of "bushrangers," who had become so formidable that the government had recently organized a company of fifty dragoons for the express purpose of hunting them down. All this did not, however, hinder the officers from making many interesting excursions, such as those to Paramatta, on the banks of the Nepean, a river very deeply embanked, where they visited the Regent Ville district; and to the "plains of Emu," a government agricultural-station, and a sort of model farm. They went to the theatre, where a grand performance was given in their honour. The delight sailors take in riding is proverbial, and it was on horseback that the French crossed the Emu plains. The noble animals, imported from England, had not degenerated in New South Wales; they were still full of spirit as one of the young officers found to his cost, when, as he was saying in English to Sir John Cox, acting as cicerone to the party, "I do love this riding exercise," he was suddenly thrown over his horse's head and deposited on the grass before he knew where he was. The laugh against him was all the more hearty as the skilful horseman was not injured.

Beyond Sir John Cox's plantations extends the unbroken "open forest," as the English call it, which can be crossed on horseback, and consists chiefly of the eucalyptus, acacias of various kinds, and the dark-leaved casuarinas. The next day, an excursion was made up the river Nepean, a tributary of the Hawkesbury, on which trip many valuable facts of natural history were obtained, Bougainville enriching his collection with canaries, waterfowl, and a very pretty species of kingfisher and cockatoos. In the neighbouring woods was heard the unpleasant cry of the lyre-pheasant and of two other birds, which feebly imitate the tinkling of a hand-bell and the jarring noise of the saw. These are not, however, the only feathered fowl remarkable for the peculiarity of their notes; we must also mention the "whistling-bird," the "knife-grinder," the "mocking-bird," the "coachman," which mimics the crack of the whip, and the "laughing jackass," with its continual bursts of laughter, which have a strange effect upon the nerves. Sir John Cox presented the commander with two specimens of the water-mole, also called the ornithorhynchus, a curious amphibious creature, the habits of which are still little known to European naturalists, many museums not possessing a single specimen.

Another excursion was made in the Blue Mountains, where the famous "King's Table-land" was visited, from which a magnificent view was obtained. The explorers gained with great difficulty the top of an eminence, and an abyss of 1600 feet at once opened beneath them; a vast green carpet stretching away to a distance of some twenty miles, whilst on the right and left were the distorted sides of the mountain, which had been rudely rent asunder by some earthquake, the irregularities corresponding exactly with each other. Close at hand foams a roaring, rushing torrent, flinging itself in a series of cascades into the valley beneath, the whole passing under the name of "Apsley's Waterfall." This trip was succeeded by a kangaroo hunt in the cow-pastures with Mr. Macarthur, one of the chief promoters of the prosperity of New South Wales. Bougainville also turned his stay at Sydney to account by laying the foundation-stone of a monument to the memory of La Pérouse. This cenotaph was erected in Botany Bay, upon the spot where the navigator had pitched his camp.

"Apsley's Waterfall."

On September 21st the Thetis and the Espérance at last set sail; passing off Pitcairn Island, Easter Island, and Juan Fernandez, now a convict settlement for criminals from Chili, after having been occupied for a half-century by Spanish vine-growers.
