Three reasons made the Government the more disposed to equip an expedition for the purpose. The first was that in June, 1800, L.G. Otto, the representative of the French Republic in London, applied for a passport for two discovery ships which were being despatched to the south seas. French men of science had for many years interested themselves in the investigation of these unknown portions of the globe. The expeditions of Laperouse (1785 to 1788) and of Dentrecasteaux (1791 to 1796) were evidence of their concern with the problems awaiting elucidation. The professors of the Museum in Paris were eager that collections of minerals and plants should be made in the southern hemisphere. The Institute of France was led by keen men of science, one of whom, the Comte de Fleurieu, had prepared the instructions for the two previous voyages. They had found a warm friend to research in Louis XVI, and the fall of the monarchy did not diminish their anxiety that France should win honour from pursuing the enquiry. They represented to Napoleon, then First Consul, the utility of undertaking another voyage, and his authorisation was secured in May. A passport was granted by Earl Spencer when Otto made the application, but there was a suspicion that the French Government was influenced by motives of policy lying deeper than the ostensible desire to promote discovery.

Secondly, the East India Company was concerned lest the French should establish themselves somewhere on the coast of Australia, and, with a base of operations there, menace the Company's trade.

Thirdly, Sir Joseph Banks, after conversations with Flinders and an examination of his charts, saw the importance of the work remaining to be done, and used his influence with the Admiralty to authorise a ship to be detailed for the purpose.

Thus imperial policy, trade interests and scientific ardour combined to procure the equipment of a new research expedition. In view of the fact that the Admiralty became officially aware in June of the intentions of the French, it cannot be said that they were precipitate in making their own plans; for it was not until December 12 that they issued their orders.

The vessel allotted for the employment was a 334-ton sloop, built in the north of England for the merchant service. She had been purchased by the Government for naval work, and, under the name of the Xenophon, had been employed in convoying merchant vessels in the Channel. Her name was changed to the Investigator, her bottom was re-coppered, the plating being put on "two streaks higher than before," and she was equipped for a three years' voyage. Flinders took command of her at Sheerness on January 25th, 1801. He was promoted to the rank of commander on the 16th of the following month.

The renovated ship was good enough to look at, and she commended herself to Flinders' eye as being the sort of vessel best fitted for the work in contemplation. In form she "nearly resembled the description of vessel recommended by Captain Cook as best calculated for voyages of discovery." But, though comfortable, she was old and unsound. Patching and caulking merely plugged up defects which the buffetings of rough seas soon revealed. But she was the best ship the Admiralty was able to spare at the time. Long before she had completed her outward voyage, however, the senility of the Investigator had made itself uncomfortably evident. Writing of the leaks experienced on the run down to the Cape, Flinders said:—

"The leakiness of the ship increased with the continuance of the southwest winds, and at the end of a week amounted to five inches of water an hour. It seemed, however, that the leaks were above the water's edge, for on tacking to the westward they were diminished to two inches. This working of the oakum out of the seams indicated a degree of weakness which, in a ship destined to encounter every hazard, could not be contemplated without uneasiness. The very large ports, formerly cut in the sides to receive thirty-two pound carronades, joined to what I have been able to collect from the dockyard officers, had given me an unfavourable opinion of her strength; and this was now but too much confirmed. Should it be asked why representations were not made and a stronger vessel procured, I answer that the exigencies of the navy were such at that time, that I was given to understand no better ship could be spared from the service; and my anxiety to complete the investigation of the coasts of Terra Australis did not admit of refusing the one offered."

The history of maritime discovery is strewn with rotten ships. Certainly if the great navigators, before venturing to face the unknown, had waited to be provided with vessels fit to make long voyages, the progress of research would have been much slower than was the case. It sounds like hyperbole to say that, when pitch and planks failed, these gallant seamen stopped their leaks with hope and ardour; but really, something like that is pretty near the truth.

The fitting out of the Investigator proceeded busily during January and February, 1801. The Admiralty was liberal in its allowances. Indeed, the equipment was left almost entirely to Banks and Flinders. The commander "obtained permission to fit her out as I should judge necessary, without reference to the supplies usually allotted to vessels of the same class." The extent to which the Admiralty was guided by Banks is indicated in a memorandum by the Secretary, Evan Nepean, penned in April. Banks wrote "Is my proposal for an alteration in the undertaking in the Investigator approved?" Nepean replied "Any proposal you may make will be approved; the whole is left entirely to your decision."

In addition to plentiful supplies and special provision for a large store of water, the Investigator carried an interesting assortment of "gauds, nick-nacks, trifles," to serve as presents to native peoples with whom it was desired to cultivate friendly relations. The list included useful articles as well as glittering toys, and is a curious document as illustrating a means by which civilisation sought to tickle the barbarian into complaisance. Flinders carried for this purpose 500 pocket-knives, 500 looking-glasses, 100 combs, 200 strings of blue, red, white and yellow beads, 100 pairs of ear-rings, 200 finger rings, 1000 yards of blue and red gartering, 100 red caps, 100 small blankets, 100 yards of thin red baize, 100 yards of coloured linen, 1000 needles, five pounds of red thread, 200 files, 100 shoemakers' knives, 300 pairs of scissors, 100 hammers, 50 axes, 300 hatchets, a quantity of other samples of ironmongery, a number of medals with King George's head imprinted upon them, and some new copper coins.
