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.
"Upon again reaching the ridge, whose moderated temperature required our care to avoid suffering from the sudden transition, we came to the granite, on whose bare surface I found a prostrate specimen of baeckea, remarkable for the regularity of its decussate leaves, which I have designated in my list as Baeckea saxicola.

Continuing to the extremity of the ridge, I was much surprised to find we had already attained the highest point of the range, and to observe another expanse, or extensive cavity, of bare white sand below us, to the South-East, the termination of which we afterwards found to be the Bald Head, of Captain Vancouver.
This part is of remarkable appearance from seaward, having on either side of its bare sandy summit a contrasting brushy vegetation: from the sea however a very small part only of its extensive surface of sand can be perceived, the greater part being only observable from the commanding hillocks we had with much exertion arrived at.

A calcareous rock (affording evidently a very considerable portion of pure lime) was seen in a decomposing state piercing the sandy surface of all parts of the ridge about Bald Head which, however, is itself a pure granite; the dense low brushy wood in its vicinity is chiefly composed of the delicate baeckea."* (*Footnote.

Cunningham manuscripts.) In the evening we visited Seal Island, and killed five seals for the sake of their skins, which were serviceable for the rigging; the boat's crew also found some penguins (Aptenodytes minor) and a nest of iguanas.
