28 Cook passes Cape Manifold, named the previous day from the Number of high Hills over it, naming Peak and Flat Islands, Cape Townshend and Shoalwater Bay.
29 Cook makes his way into Thirsty Sound, where he had hopes of laying the Ship a Shore to Clean her bottom but abandoned the idea due to an apparent absence of fresh water, though his investigations produced several places where a Ship might be laid ashore with safety.
30 Cook makes another attempt to find fresh water in Thirsty Sound and lands upon a pretty high Hill, which is at the North-West entrance of the inlet …. in order to take a view of the Sea Coast and Islands, etc., that lay off it, and to take their bearings …. We met with no fresh water, or any other kind of refreshments whatever; we saw 2 Turtle, but caught none, nor no sort of Fish or wild fowl, except a few small land birds. Here are the same sort of Water Fowl as we saw in Botany Bay …. No signs of Fertility is to be seen upon the Land …. All the low lands are mostly overrun with Mangroves …. Up in the lakes, or lagoons, I suppose, are shell fish, on which the few Natives subsist. We found Oysters sticking to most of the Rocks upon the Shore, which were so small, as not to be worth the picking off.
31 Cook passed between the Duke Islands and the maze of reefs and islands lying north-west of Thirsty Sound.
