On the other side of the Pacific was a country where such a cargo might, with luck, be sold at a bounding profit.

He could easily find out how the trade was done.

There was more than one among those with whom he would associate in Sydney who knew a great deal about it.
One or two sentences in Bass's last letters to Henry Waterhouse contain mysterious hints, which to him, with his experience of Port Jackson, would be significant.

He explained that he intended taking the Venus to visit the coast of Chili in search of provisions, "and that they may not in that part of the world mistake me for a contrabandist, I go provided with a very diplomatic-looking certificate from the Governor here, stating the service upon which I am employed, requesting aid and protection in obtaining the food wanted.

And God grant you may fully succeed, says your warm heart, in so benevolent an object; and thus also say I; Amen, say many others of my friends." But was the diplomatic-looking paper intended rather to serve as a screen than as a guarantee of bona fides?
"In a few hours," wrote Bass at the beginning of February, 1803, "I sail again on another pork voyage, but it combines circumstances of a different nature also"; and at the end of the same letter he added: "Speak not of South America to anyone out of your family, for there is treason in the very name." What did he mean by that?
He spoke of "digging gold in South America," and clearly did not mean it in the strict literal sense.
It is true that the Governor was anxious to get South American cattle and beef for the settlement in Sydney, but can that have been the only motive for a voyage beyond Tahiti?
"If our approaching voyage proves at all fortunate in its issue, I expect to make a handsome thing out of it, and to be much expedited on my return to old England," Bass wrote in January.
He would not have been likely to make so very handsome a thing out of beef in one voyage, to enable him to expedite his return to England.
The factors of the case are, then, that Bass had on his hands a large quantity of goods which he had failed to sell in Sydney; that there was a considerable and enormously profitable contraband trade with South America at the time; that he expected to make a very large and rapid profit out of the venture he was about to undertake; that he warned Waterhouse against mentioning the matter outside the family circle, "for there is treason in the very name"; and that he was himself a man distinguished by dash and daring, who was very anxious to make a substantial sum and return to England soon.
