At daybreak the next morning an opportunity offered to cross the sound, and by eight o'clock the brig was anchored under Seal Island; upon which we commenced the repair of the rigging, and in the course of the day shifted the main topmast. We had left the anchorage on the other side of the sound too early for our friends the natives, who had promised last evening to bring us a hawk's nest that was built upon a rock near the watering-place; at ten o'clock a very large fire was perceived close to the nest; it was no doubt kindled by them, and meant to show that they were not inattentive to their promise. January 4. The following day some natives were seen about a mile off upon the beach but did not come near the vessel. Mr. Cunningham botanised upon the summit of Bald Head. Of this excursion he gave me the following account: "Upon reaching the summit of the ridge, and clearing a rocky gully which intersected our track, we instantly entered an elevated valley of pure white sand, bounded on either side by ridges forty feet high, that were in themselves totally bare, excepting on the tops, where a thin clothing of shrubs was remarked; the whole surface reflected a heat scarcely supportable, and the air was so stagnant as scarcely to be respired, although we were at a considerable elevation, and in the vicinity of a constant current of pure atmospheric air on the ridge. After traversing the whole length of this sandy vale, which is one-third of a mile in extent, in our route towards Bald Head, with scarcely a plant to attract our attention, we perceived at its extremity some remarkably fine specimens of Candollea cuneiformis, Labil., which had, in spite of the poverty and looseness of the drifting sand, risen to large spreading trees, sixteen feet high, of robust growth and habit; they were at this time covered with flowers and ripe fruit; but so painful was it to the eyes and senses to remain for a moment stationary in this heated valley, that whilst I gathered a quantity of the seeds of this truly rich plant, my servant was obliged to hurry away to a cooler air on the ridge, which we had again nearly reached; and but for this fine plant, and the no less conspicuous blue-flowered Scaevola nitida, Br. The whole scene would have deeply impressed us with all the horrors that such extremes of aridity are naturally calculated to excite.
