“The requisite properties are, salubrity of climate, a good harbor, a position in the track of steam-navigation, conveniency of position for ships disabled in typhoons, conveniency of position for our cruisers during war, and a locality strong and circumscribed by nature, so as to be readily capable of cheap defence.
“Labuan lies in about 6° of north latitude, and consequently the average heat will be about 83° of Fahrenheit; the utmost range of the thermometer will not exceed ten degrees. In short, the year is a perpetual hot summer. It is, at the same time, well ventilated by both monsoons; and being near twenty miles from the marshy shores of the Borneo river, there is little ground to apprehend that it will be found unhealthy, even if those shores themselves had been ascertained to be so, which, however, is not the case; for, in proof of their salubrity, it may be stated, that the town of Borneo is healthy, although it stands, and has stood for centuries, on the flooded banks of the river; the houses being built on posts, and chiefly accessible by boat.
“With respect to harbor, a most essential point, I do not perceive that the island is indented by any bay or inlet that would answer the purpose of one.[1] The channel, however, which lies between it and the mainland of Borneo is but seven miles broad, and will probably constitute a spacious and convenient harbor. The name of the island itself, which means anchorage, I have no doubt is derived from the place affording shelter to native shipping, and those probably, in most cases, fleets of pirate prahus. This channel is again further restricted by four islets, and these, with four more lying to the southwest, will afford shelter in the southwest or mild monsoon; protection is given in the northeast, the severest monsoon, by Labuan itself: and I may add, that the island is, by four degrees of latitude, beyond the extreme southern limit of the typhoons of the Chinese Sea.
“In the channel between Labuan and the main, or rather between Labuan and the islets already mentioned, the soundings on the Admiralty chart show that vessels drawing as much as eighteen feet water may anchor within a mile of the shore, and the largest vessels within a mile and a half; a convenience for shipping which greatly exceeds that of Singapore. One of the advantages of Labuan will be that it will prove a port of refuge for shipping disabled in the storms of the Chinese Seas. Many examples, indeed some of recent occurrence, might be adduced to show the need there is of such a port.
“Labuan lies nearly in the direct track both of steam and sailing navigation from India to China, during the northeast, the worst and severest of the two monsoons; and is as intermediate a position between Singapore and Hong Kong as can be found, being 700 miles from the former and 1000 from the latter.
“The insular character and narrow limits of Labuan will make it easily and cheaply defensible. The extreme length of the island appears to be about six miles, its greatest breadth about four and a half, and probably its whole area will not be found to exceed thirty square miles.
“From the rude tribes of the immediate vicinity no hostile attack is to be apprehended that would make the present erection of forts or batteries necessary. No Asiatic enemy is at any time to be feared that would make such defences requisite. In five-and-twenty years it has not been found imperative to have recourse to them at Singapore. It is only in case of war with a naval power that fortifications would be required; but I am not informed what local advantages Labuan possesses for their erection. A principal object of such fortifications would be the defence of the shipping in the harbor from the inroads of an enemyʼs cruisers. At one point the soundings, as given in the Admiralty chart, are stated nine fathoms, within three quarters of a mile of the shore; and I presume that batteries within this distance would afford protection to the largest class of merchantmen. In Singapore Roads no class of shipping above mere native craft can lie nearer than two miles of the shore; so that in a war with a European naval power, the merchant shipping there can only be defended by her majestyʼs navy.
“One of the most striking national advantages to be expected from the possession of Labuan would consist in its use in defending our own commerce, and attacking that of opponents, in the event of a naval war. Between the eastern extremity of the Straits of Malacca and Hong Kong, a distance of 1700 miles, there is no British harbor, and no safe and accessible port of refuge; Hong Kong is, indeed, the only spot within the wide limits of the Chinese Sea for such a purpose, although our legitimate commercial intercourse within it extends over a length of 2000 miles. Everywhere else, Manilla and the newly opened ports of China excepted, our crippled vessels or our merchantmen pursued by the enemyʼs cruisers, are met by the exclusion or extortion of semi-barbarous nations, or in danger of falling into the power of robbers and savages.
“Labuan fortified, and supposing the Borneon coal to be as productive and valuable in quality as it is represented, would give Great Britain in a naval war the entire command of the China Sea. This would be the result of our possessing or commanding the only available supply of coal, that of Bengal and Australia excepted, to be found in the wide limits which extend east of the continents of Europe and America.
“The position of Labuan will render it the most convenient possible for the suppressing of piracy. The most desperate and active pirates of the whole Indian Archipelago are the tribes of the Sooloo group of islands lying close to the north shore of Borneo, and the people of the north and northeastern coast of Borneo itself; these have of late years proved extremely troublesome both to the English and Dutch traders; both nations are bound by the Convention of 1824 to use their best endeavors for the suppression of piracy, and many efforts have certainly been made for this purpose, although as yet without material effect in diminishing the evil.
