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.
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.
On the 23rd November the Thetis, which had been separated from the Espérance during a heavy storm, anchored off Valparaiso, where it met Admiral de Rosamel's division. Great excitement prevailed in the roadstead, for an expedition against the island of Chiloë, which still belonged to Spain, was being organized by the chief director, General Ramon Freire y Serrano, of whom we have already spoken.
Bougainville, like the Russian navigator Lütke, is of opinion that the position of Valparaiso does not justify its reputation. The streets are dirty and narrow, and so steep that walking in them is very fatiguing. The only pleasant part is the suburb of Almendral, which, with its gardens and orchards, would be still more agreeable but for the sand-storms prevalent throughout nearly the whole of the year. In 1811, Valparaiso numbered only from four to five thousand inhabitants; but in 1825 the population had already tripled itself, and the increase showed no sign of ceasing. When the Thetis touched at Valparaiso, the English frigate, the Blonde, commanded by Lord Byron, grandson of the explorer of the same name, whose discoveries are narrated above, was also at anchor there. By a singular coincidence Byron had raised a monument to the memory of Cook in the island of Hawaii, at the very time when Bougainville, the son of the circumnavigator, met by Byron in the Straits of Magellan, was laying the foundation-stone of the monument to the memory of La Pérouse in New South Wales.
Bougainville turned the delay necessary for the revictualling of his division to account by paying a visit to Santiago, the capital of Chili, thirty-three leagues inland. The environs of Chili are terribly bare, without houses or any signs of cultivation. Its steeples alone mark the approach to it, and one may fancy oneself still in the outskirts when the heart of the city is reached. There is, however, no lack of public buildings, such as the Hôtel de la Monnaie, the university, the archbishop's palace, the cathedral, the church of the Jesuits, the palace, and the theatre, the last of which is so badly lighted that it is impossible to distinguish the faces of the audience. The promenade, known as La Cañada, has now supplanted that of L'Alameda on the banks of the river Mapocha, once the evening rendezvous. The objects of interest in the town exhausted, the Frenchmen examined those in the neighbourhood, visiting the Salto de Agua, a waterfall of 1200 feet in height, the ascent to which is rather arduous, and the Cerito de Santa-Lucia, from which rises a fortress, the sole defence of the town.
The season was now advancing, and no time was to be lost if the explorers wished to take advantage of the best season for doubling Cape Horn. On the 8th January, 1826, therefore, the two vessels once more put to sea, and rounded the Cape without any mishap, though landing at the Falklands was rendered impossible by fog and contrary winds. Anchor was cast on the 28th March in the roadstead of Rio Janeiro, and, as it turned out, at a time most favourable for the French to form an accurate opinion alike on the city and the court.
"The emperor," says Bougainville, "was upon a journey at the time of our arrival, and his return was the occasion of fêtes and receptions which roused the population to activity, and broke for a time the monotony of ordinary life in Rio, that dullest and dreariest of towns to the foreigner. Its environs, however, are charming; nature has in them been lavish of her riches; and the vast harbour, the Atlantic, rendezvous of the commercial world, presents a most animated scene. Innumerable ships, either standing in or getting under weigh, small craft cruising about, a ceaseless roar of cannon from the forts and men-of-war, exchanging signals on the occasion of some anniversary or the celebration of some festival of the church, whilst visits were constantly being exchanged between the officers of the various foreign vessels and the diplomatic agents of foreign powers at the court of Rio."
The division set sail again on the 11th April, and arrived at Brest on the 24th June, 1826, without having put into port since it left Rio Janeiro. We must remember that if Bougainville did not make any discoveries on this voyage, he had no formal instructions to do so, his mission being merely to unfurl the flag of France where it had as yet been rarely seen. None the less do we owe to this general officer some very interesting, and in some cases new information on the countries visited by him. Some of the surveys made by his expedition may be of service to navigators, and it must be owned that the hydrographical researches which alone could be undertaken in the absence of scientific men were carefully made, and resulted in the obtaining of numerous and accurate data. We can but sympathize with the commander of the Thetis, in his expression of regret, in the preface to his journal, that neither the Government nor the Académie des Sciences had seen fit to turn his expedition to account to obtain new results supplementary of the rich harvest gleaned by his predecessors.
The expedition next sent out under the command of Captain Dumont d'Urville was merely intended by the minister to supplement and consolidate the mass of scientific data collected by Captain Duperrey in his voyage from 1822 to 1824. As second in command to Duperrey, and the originator and organizer of the new exploring expedition, D'Urville had the very first claim to be appointed to its command. The portions of Oceania he proposed to visit were New Zealand, the Fiji Islands, the Loyalty Islands, New Britain, and New Guinea, all of which he considered urgently to demand the consideration alike of the geographer and the traveller. What he effected in this direction we shall ascertain by following him step by step. An interest of another character also attaches to this trip, but it will be well to quote on this point the instructions given to the navigator.
"An American captain," writes the Minister of Marine, "said that he saw in the hands of the natives of an isle situated between New Caledonia and the Louisiade Archipelago a cross of St. Louis and some medals, which he imagined to be relics of the wrecked vessel of the celebrated La Pérouse, whose loss is so deeply and justly regretted. This is, of course, but a feeble reason for hoping that some of the victims of the disaster still survive; but you, sir, will give great satisfaction to his Majesty, if you are the means of restoring any one of the poor shipwrecked mariners to their native land after so many years of misery and exile."
The aims of the expedition were therefore manifold, and by the greatest chance it was able to achieve them nearly all. D'Urville received his appointment in December, 1825, and was permitted himself to choose all who were to accompany him. He named as second in command Lieutenant Jacquinot, and as scientific colloborateurs Messrs. Quoy and Gaimard, who had been on board the Uranie, and as surgeon Primevère Lesson. The Coquille, the excellent qualities of which were well known to D'Urville, was the vessel selected; and the commander having named her the Astrolabe in memory of La Pérouse, embarked in her a crew of twenty-four men. Anchor was weighed on the 25th April, and the mountains of Toulon with the coast of France were soon out of sight.
After touching at Gibraltar, the Astrolabe stopped at Teneriffe to take in fresh provisions before crossing the Atlantic, and D'Urville took advantage of this delay to ascend the peak, accompanied by Messrs. Quoy, Gaimard, and several officers, a bad road, very arduous for pedestrians, leading the first part of the way over fields of scoria, though as Laguna is approached the scenery improves. This town, of a considerable size, contains but a small, indolent, and miserable population.
Between Matunza and Orotara the vegetation is magnificent, and the luxuriant foliage of the vine enhances the beauty of the view. Orotara is a small seaboard town, with a port affording but little shelter. It is well-built and laid out, and would be comfortable enough if the streets were not so steep as to make traffic all but impossible. After three-quarters of an hour's climb through well-cultivated fields, the Frenchmen reached the chestnut-tree region, beyond which begin the clouds, taking the form of a thick moist fog, very disagreeable to the traveller. Further on comes the furze region, beyond which the atmosphere again becomes clear, vegetation disappears, the ground becomes poorer and more barren. Here are met with decomposed lava, scoria, and pumice-stones in great abundance, whilst below stretches away the boundless sea of clouds.
Thus far hidden by clouds or by the lofty mountains surrounding it, the peak at last stands forth distinctly, the incline becomes less steep, and those vast plains of intensely melancholy appearance, called Cañadas by the Spanish, on account of their bareness, are crossed. A halt is made for lunch at the Pine grotto before climbing the huge blocks of basalt ranged in a circle about the crater, now filled in with ashes from the peak, and forming its enceinte. The peak itself is next attached, the ascent of which is broken one-third of the way up by a sort of esplanade called the Estancia de los Ingleses. Here our travellers passed the night, not perhaps quite so comfortably as they would have done in their berths, but without suffering too much from the feeling of suffocation experienced by other explorers. The fleas, however, were very troublesome, and their unremitting attacks kept the commander awake all night.
At four a.m. the ascent was resumed, and a second esplanade, called the Alta Vista, was soon reached, beyond which all trace of a path disappears, the rest of the ascent being over rough lava as far as the Chahorra Cone, with here and there, in the shade, patches of unmelted snow. The peak itself is very steep, and its ascent is rendered yet more arduous by the pumice-stone which rolls away beneath the feet.
"At thirty-five minutes past six," says M. Dumont d'Urville, "we arrived at the summit of the Chahorra, which is evidently a half-extinct crater. Its sides are thin and sloping, it is from sixty to eighty feet deep, and the whole surface is strewn with fragments of obsidian, pumice-stones, and lava. Sulphureous vapour, forming a kind of crown of smoke, is emitted from it, whilst the atmosphere at the bottom is perfectly cool. At the summit of the peak the thermometer marked 11°, but in my opinion it was affected by the presence of the fumerolles, for when at the bottom of the crater it fell rapidly from 19° in the sun to 9° 5' in the shade."
The descent was accomplished without accident by another route, enabling our travellers to examine the Cueva de la Nieve, and to visit the forest of Aqua Garcia, watered by a limpid stream, and in which D'Urville made a rich collection of botanical specimens.
In Major Megliorini's rooms at Santa Cruz the commander was shown, together with a number of weapons, shells, animals, fish, &c., a complete mummy of a Guanche, said to be that of a woman. The corpse was sewn up in skins, and seemed to be that of a woman five feet four high, with regular features and large hands. The sepulchral caves of the Guanches also contained earthenware, wooden vases, triangular seals of baked clay, and a great number of small discs of the same material, strung together like chaplets, which may have been used by this extinct race for the same purposes as the "quipos" of the Peruvians.
On the 21st June the Astrolabe once more set sail and touched at La Praya, and at the Cape Verd Islands, where D'Urville had hoped to meet Captain King, who would have been able to give him some valuable hints on the navigation of the coast of New Guinea. King, however, had left La Praya thirty-six hours previously, and the Astrolabe therefore resumed her voyage the next day, i.e. on the 30th June.
On the last day of July the rocks of Martin-Vaz and Trinity Island were sighted, and the latter appearing perfectly barren, a little dried-up grass and a few groups of stunted trees, dotted about amongst the rocks, being the only signs of vegetation.
D'Urville had been very anxious to make some botanical researches on this desert island, but the surf was so rough that he was afraid to risk a boat in it.
On the 4th August the Astrolabe sailed over the spot laid down as "Saxembourg" Island, which ought to be finally erased from French as it has been from English charts; and after a succession of squalls, which tried her sorely, she arrived off St. Paul and Amsterdam Islands, finally anchoring on the 7th October in King George's Sound, on the coast of Australia. In spite of the roughness of the sea, and constant bad weather throughout his voyage of 108 days, D'Urville had carried on all his usual observations on the height of the waves, which he estimated at 80 and occasionally as much as 100 feet, off Needle Bank; the temperature of the sea at various depths, &c.
Captain Jacquinot having found a capital supply of fresh water on the right bank of Princess Royal Harbour, and at a little distance a site suitable for the erection of an observatory, the tents were soon pitched by the sailors, and several officers made a complete tour of the bay, whilst others opened relations with the aborigines, one of whom was induced to go on board, though it was only with the greatest difficulty that he was persuaded to throw away his Banksia, a cone used to retain heat, and to keep the stomach and the front part of the body warm. He remained quietly enough on board for two days, however, eating and drinking in front of the kitchen fire. In the meantime his fellow-countrymen on land were peaceable and well-disposed, even bringing three of their children into the camp.
During this halt a boat arrived manned by eight Englishmen, who asked to be taken on board as passengers, and told such a very improbable story of having been deserted by their captain, that D'Urville suspected them of being escaped convicts; a suspicion which became a conviction, when he saw the wry faces they made at his proposal to send them back to Port Jackson. The next day, however, one took a berth as sailor, and two were received as passengers; whilst the other five decided to remain on land and drag out a miserable existence amongst the natives.
All this time hydrographical and astronomical observations were being made, and the hunters and naturalists were trying to obtain specimens of new varieties of fauna and flora. The delays extending to October 24th enabled the explorers to regain their strength, after their trying voyage, to make the necessary repairs, take in wood and water, draw up a map of the whole neighbourhood, and to collect numerous botanical and zoological specimens. His observations of various kinds made D'Urville wonder that the English had not yet founded a colony on King George's Sound, admirably situated as it is, not only for vessels coming direct from Europe, but for those trading between the Cape and China, or bound for the Sunda Islands, and delayed by the monsoons. The coast was explored as far as West Port, preferred by D'Urville to Port Dalrymple, the latter being a harbour always difficult and often dangerous either to enter or to leave. West Port moreover, was as yet only known from the reports of Baudin and Flinders, and it was therefore better worth exploring than a more frequented district. The observations made in King George's Sound were therefore repeated at West Port, resulting in the following conclusions: —
"It affords," says D'Urville, "an anchorage alike easy to reach and to leave, the bottom is firm, and wood is abundant and easily procurable. In a word, when a good supply of fresh water is found, and that will probably be soon, West Port will rise to a position of great importance in a channel such as Bass's Straits, when the winds often blow strongly from one quarter for several days together, the currents at the same time rendering navigation difficult."
From November 19th to December 2nd the Astrolabe cruised along the coast, touching only at Jervis Bay, remarkable for its magnificent eucalyptus forests.
The reception given to the French at Port Jackson, by Governor Darling and the colonial authorities, was none the less cordial for the fact that the visits made by D'Urville to various parts of New Holland had greatly amazed the English Government.
During the last three years Port Jackson had increased greatly in size and improved in appearance; though the population of the whole colony only amounted to 50,000, and that in spite of the constant foundation of new English settlements. The commander took advantage of his stay in Sydney to forward his despatches to France, together with several cases of natural history specimens. This done and a fresh stock of provisions having been laid in, he resumed his voyage.
It would be useless to linger with Dumont d'Urville at New South Wales, to the history of which, and its condition in 1826, he devotes a whole volume of his narrative. We have already given a detailed account of it, and it will be better to leave Sydney with our traveller, on the 19th December, and follow him to Tasman Bay, through calms, head-winds, currents, and tempests, which prevented his reaching New Zealand before the 14th January, 1827. Tasman Bay, first seen by Cook on his second voyage, had never yet been explored by any expedition, and on the arrival of the Astrolabe a number of canoes, containing some score of natives, most of them chiefs, approached. These natives were not afraid to climb on board, some remaining several days, whilst later arrivals drew up within reach, and a brisk trade was opened. Meanwhile several officers climbed through the thick furze clothing the hills overlooking the bay, and the following is D'Urville's verdict on the desolate scene which met their view.
"Not a bird, not an insect, not even a reptile to be seen, the solemn, melancholy silence is unbroken by the voice of any living creature." From the summit of these hills the commander saw New Bay, that known as Admiralty, which communicates by a current with that in which the Astrolabe was anchored; and he was anxious to explore it, as it seemed safer than that of Tasman, but the currents several times brought his vessel to the very verge of destruction; and had the Astrolabe been driven upon the rocky coast, the whole crew would have perished, and not so much as a trace of the wreck would have been left. At last, however, D'Urville succeeded in clearing the passage with no further loss than that of a few bits of the ship's keel.
"To celebrate," says the narrative, "the memory of the passage of the Astrolabe, I conferred upon this dangerous strait the name of the 'Passe des Français'" (French Pass), "but, unless in a case of great necessity, I should not advise any one else to attempt it. We could now look calmly at the beautiful basin in which we found ourselves; and which certainly deserves all the praise given to it by Cook. I would specially recommend a fine little harbour, some miles to the south of the place, where the captain cast anchor. Our navigation of the 'Passe des Français' had definitively settled the insular character of the whole of the district terminating in the 'Cape Stephens' of Cook. It is divided from the mainland of Te-Wahi-Punamub16 by the Current Basin. The comparison of our chart with that of the strait as laid down by Cook will suffice to show how much he left to be done."
The Astrolabe soon entered Cook's Strait, and sailing outside Queen Charlotte's Bay, doubled Cape Palliser, a headland formed of some low hills. D'Urville was greatly surprised to find that a good many inaccuracies had crept into the work of the great English navigator, and in that part of the account of his voyage which relates to hydrography, he quotes instances of errors of a fourth, or even third of a degree.
The commander then resolved to make a survey of the eastern side of the northern island Ika-Na-Mawi. On this island pigs were to be found, but no "pounamon" the green jade which the New Zealanders use in the manufacture of their most valuable tools; strange to say, however, jade is to be found on the southern island, but there are no pigs.
Two natives of the island, who had expressed a wish to remain on board the corvette, became quite low-spirited as they watched the coast of the district where they lived disappear below the horizon. They then began to repent, but too late, the intrepidity which had prompted them to leave their native shores; for intrepid they justly deserve to be called, seeing that again and again they asked the French sailors if they were not to be eaten, and it took several days of kind treatment to dispel this fear from their minds.
D'Urville continued to sail northward up the coast until the capes, named by Cook Turn-again and Kidnappers, had been doubled, and Sterile Island with its "Ipah" came in sight. In the Bay of Tolaga, as Cook called it, the natives brought alongside the corvette pigs and potatoes, which they readily exchanged for articles of little value. On other canoes approaching, the New Zealanders who were on board the vessel urged the commander to fire upon and kill their fellow-countrymen in the boats; but as soon as the latter climbed up to the deck, the first arrivals advanced to greet them with earnest assurances of friendship. Conduct so strangely inconsistent is the outcome of the compound of hatred and jealousy mutually entertained for each other by these tribes. "They all desire to appropriate to themselves exclusively whatever advantage may be obtained from the visits of foreigners, and they are distressed at the prospect of their neighbours getting any share." Proof was soon afforded that this explanation is the right key to their behaviour.
Upon the Astrolabe were several New Zealanders, but among them was a certain "Shaki" who was recognized as a chief by his tall stature, his elaborate tattooing, and the respectful manner in which he was addressed by his fellow-islanders. Seeing a canoe manned by not more than seven or eight men approaching the corvette, this "Shaki" and the rest came to entreat D'Urville most earnestly to kill the new arrivals, going so far as to ask for muskets that they might themselves fire upon them. However, no sooner had the last comers arrived on board than all those who were there already overwhelmed them with courtesies, while the "Shaki" himself, although he had been one of the most sanguinary, completely changed his tone and made them a present of some axes he had just obtained. After the chief men of a warlike and fierce appearance, with faces tattooed all over, had been a few minutes on board, D'Urville was preparing to ask them some questions, with the aid of a vocabulary published by the missionaries, when all at once they turned away from him, leaped into their canoes and pushed out into the open sea. This sudden move was brought about by their countrymen, who, for the purpose of getting rid of them, slily hinted that their lives were in danger, as the Frenchmen had formed a plot to kill them.
It was in the Bay of Tolaga, the right name of which is Houa-Houa, that D'Urville found the first opportunity of gaining some information about the "kiwi," by means of a mat decorated with the feathers of that bird, such mats being articles of luxury among these islanders. The "kiwi" is about the size of a small turkey, and, like the ostrich, has not the power of flying. It is hunted at night by the light of torches and with the assistance of dogs. It is this bird which is also known under the name of the "apteryx." What the natives told D'Urville about it was in the main accurate. The apteryx, with the tail of a fowl and a plumage of a reddish-brown, has an affinity to the ostrich; it inhabits damp and gloomy woods, and never comes out even in search of food except in the evening. The incessant hunting of the natives has considerably diminished the numbers of this curious species, and it is now very rare.
D'Urville made no pause in the hydrographical survey of the northern island of New Zealand, keeping up daily communication with the natives, who brought him supplies of pigs and potatoes. According to their own statements, the tribes were perpetually at war with one another, and this was the true cause of the decrease in the population of these islands. Their constant demand was for fire-arms; failing to obtain these, they were satisfied if they could get powder in exchange for their own commodities.
On the 10th February, when not far from Cape Runaway, the corvette was caught in a violent storm, which lasted for thirty-six hours, and she was more than once on the point of foundering. After this, she made her way into the Bay of Plenty, at the bottom of which rises Mount Edgecumbe; then keeping along the coast, the islands of Haute and Major were sighted; but during this exploration of the bay, the weather was so severe that the chart of it then laid down cannot be considered very trustworthy. After leaving this bay, the corvette reached the Bay of Mercury; surveyed Barrier Island, entered Shouraki or Hauraki Bay, identified the Hen and Chickens and the Poor Knights Islands, finally arriving at the Bay of Islands. The native tribes met with by D'Urville in this part of the island were busy with an expedition against those of Shouraki and Waikato Bays. For the purpose of exploring the former bay, which had been imperfectly surveyed by Cook, D'Urville sailed back to it, and discovered that that part of New Zealand is indented with a number of harbours and gulfs of great depth, each one being safer, if possible, than the other. Having been informed that by following the direction of the Wai Magoia, a place would be reached distant only a very short journey from the large port of Manukau, he despatched some of his officers by that route, and they verified the correctness of the information he had received. This discovery, observes Dumont d'Urville, may become of great value to future settlements of Shouraki Bay; and this value will be still farther increased should the new surveys prove that the port of Manukau is accessible to vessels of a certain size, for such a settlement would command two seas, one on the east and the other on the west.
