During these two days the labours of the expedition have commenced. We have laid down the soundings on parts of the Abrolhos, which were left undone by Baron Roussin. The depth varied to an unusual extent: at one cast of the lead there would be 20 fathoms & in a few minutes only 5. The scene being quite new to me was very interesting. Everything in such a state of preparation; sails all shortened & snug: anchor ready to let fall: no voice or noise to be heard, excepting the alternate cry of the leadsmen in the chains. We anchored for the night.
