As it blew very fresh all night, I landed the next morning abreast of the Supply, with the midshipman and surgeon: we walked across the island to the bay which I had seen the day before. After ascending a very steep hill, we got to the top of the island, which we found to be a plain, but every foot of ground was covered with trees, or the large roots of trees which rose above the surface of the earth; these were not the only impediments to our march, as it was impossible for us to walk four yards, without encountering an almost impenetrable net-work, composed of a large kind of supple-jack, or vine; which was so very strong, as to suppress the growth of several trees, by bending them in every direction; and they so completely stopped our progress, that we were obliged to cut our way through them. No grass, or herb of any kind, grew between the roots of these trees, although the soil every where was extremely rich and good; but this may be attributed to the total exclusion of the sun, and the want of air, which doubtless prevent this sort of vegetation. The pines, which are numerous, are of an incredible growth: one of them, which had been blown down, or had fallen by age, measured 140 feet in length, and several which were measured standing, were 30 feet in circumference: they grow quite straight, and have no branches for near 80 feet from the ground. We found it impracticable to get into Anson's bay, although we saw down into it; but the hill over it was a perpendicular cliff, with a large kind of iris growing on the sides of it, which was a providential circumstance, for, in our endeavour to get into the bay, we were all in the greatest danger of falling down the cliff; indeed, if the iris had not been sufficiently strong to have supported our weight, we must have fallen down a depth of 90 feet. We were too much pleased with, and thankful for our escape, to attempt a second trial, as the whole of this side of the island had the same steep appearance. In our return, we frequently heard a very distinct cry of "yaho," which seemed as if it was uttered by an animal or bird. During this excursion, we did not see a leaf of flax, or any herb whatever; the ground, although a rich and deep soil, being quite bare, which is rather extraordinary, as Captain Cook says that the flax plant is rather more luxuriant here than at New Zealand. We saw pigeons, parrots, parroquets, doves, and a variety of other birds, in great numbers, and so very tame, that they might be knocked down with a stick. Large pieces of pumice stone were seen in every part; probably a crater, or the remains of one, may be found at, or near a mountain, which rises to a considerable height in the middle of the island, and which I called Mount Pitt, in honour of the chancellor of the exchequer.
