Thus furnished, they went off about eleven o'clock in the forenoon, and to my very great uneasiness, I heard no more of them for four days. The whole ship's company were indeed surprised at their stay, and the captain of the sloop would fain have had me let him have sailed up the river with the sloop, as far as the channel would serve; which really we found was deep enough. Indeed, as I was unwilling to run any more risks, I could not persuade myself, but that the force I had already sent was sufficient to fight five thousand naked creatures, such as the natives seemed to be, and therefore, I was very unwilling to send. However, I consented at last to have our long-boat and two smaller boats manned with fifty-four men more, very well armed, and covered from arrows and darts as the other had been, to go up the river, upon their solemn promise, and with express order, to return the next day, at farthest; ordering them to fire guns as they went up the river, to give notice to their fellows, if they could be heard, that they were coming; and that, in the mean time, if I fired three guns they should immediately return. They went away with the tide of flood, a little before noon, and went up the river about five leagues, the tide running but slowly, and a strong fresh of land-water that checked the current coming down; so that when the tide was spent they came to an anchor. They found the river, contrary to their expectation, continued both deep enough, and was wider in breadth than where the ships were at anchor; and that it had another mouth or outlet into the sea some leagues farther east, so that the land to the east of us, where our men went on shore, was but an island, and had not many inhabitants, if any; the people they had seen there having possibly swam over the other arm or branch of the river, to observe our ships the nearer. As our men found they could go no farther for want of the tide, they resolved to come to an anchor; but, just as they were sounding, to see what ground they had, and what depth, a small breeze at north-east sprang up, by which they stemmed the current and reached up about two leagues farther, when they hove over their grappling in five fathom water, soft ground; so that all this way, and much farther, every one of our ships might have gone up the channel, being as broad as the Thames is about Vauxhall. It must be observed, that all along this river they found the land, after they came past the place where the other branch of the river broke off, eastward, was full of inhabitants on both sides, who frequently came down to the water-side in haste to look at our boats; but always when our men called to them, as if they thought our men inquired after their fellows, they pointed up the river, which was as much as to say, they were gone farther that way.
