We were no sooner clear of the harbour, than the wind veered more to the southward, and began to blow strong, with thick, hazy, and dirty weather; and, what gave me privately a good deal of concern, the carpenter reported, that the ship, which had hitherto been very tight, now made water.  This piece of information, with such a voyage as the Sirius was now entered upon, was no doubt very unwelcome; and more particularly so, when it was considered, that the ship’s company, from having been long upon salt diet, without the advantage of any sort of vegetables, were not so healthy and strong as a leaky ship might require.

I had often observed, that when this voyage, upon which we were now entered, was the subject of conversation, in company with the governor, he always spoke in favour of the passage round Van Diemen’s land, and to the westward; but when I signified a wish that he would direct by what route I should endeavour to perform the voyage, he declined that; and said that I should be governed by circumstances, and that he should leave it to my discretion and judgment; at the same time expressing his opinion strongly in favour of the western route; which I confess I was a little surprised at, as it had never yet been attempted, not even by ships employed in that kind of service which leaves it in their power to make experiments.

I do not say that the passage from Van Diemen’s land to the Cape of Good Hope, by the westward, is impracticable, as that remains yet to be tried; but from my own experience of the prevalence of strong westerly winds across that vast ocean, I am inclined to think it must be a long and tedious voyage; and at the same time so very uncertain, that the time for which the Sirius was victualled, (for four months, and of some articles not more than two weeks, for the number of men on board; having left a considerable quantity of our provision for the use of the settlement,) and the nature of the service she was going upon, which was no doubt of considerable consequence to the colony, was not an opportunity for trying such an experiment; as the consequence of a disappointment would have been, that I must have returned again to Port Jackson for a fresh supply of provisions, and the season for another passage would have been too far advanced.  I therefore determined, judging from the experience of those who had before made the eastern passage, to pass to the southward of New Zealand and round Cape Horn.

We stood off to the eastward, determined as early as possible to get an offing of fifty or sixty leagues; the wind continued to the southward, with the same hazy and squally weather, until the 5th, when it shifted to south-south-east; by this time we were about 70 leagues from the coast, which enabled us to tack and stand to the south-west:  with this change of wind from the south-west to the south-east quarter, the same squally and unsettled weather continued.  The ship upon the larboard tack made much more water than on the starboard, so much as to render it necessary to pump her every two hours, to prevent too long a spell; she made in general from ten to twelve inches in two hours.
