a small stream taking its course to the sea.  To the north and south the country was mountainous and broken beyond any thing we had seen.  Indeed, some idea of those barrier mountains may be formed from the circumstance, that although we could distinctly see the ocean, and the waving of the coast line, (which within the distance of ten or twelve miles from the beach appeared low), yet we were still nearly fifty miles from it.  I estimated the height of this mountain at between six and seven thousand feet; and yet the country north and south appeared equally elevated.  Numerous smokes arising from natives’ fires announced a country well inhabited, and gave the whole picture a cheerful aspect, which reflected itself on our minds; and we returned to the tents with lighter hearts and better prospects.  In removing the baggage left at the bottom of the hill a short quarter of a mile, a most distressing accident occurred.  A mare, one of the strongest we had, in bringing up a very light load, not a quarter of her usual burden, and when within one hundred yards of the tent, literally burst with the violent exertion which the ascent required.  In this shocking state, with her entrails on the ground, she arrived at the tent, when, to put an end to her agonies, she was shot.  This was a serious loss to us, in addition to that which we suffered on the day before:  and three more horses were so worn, that I scarcely expected to force them along even unladen.  It must not be supposed that we attempted to climb these hills in a direct line; it would have been scarcely possible for a man to do it:  we wound round them in every practicable direction; and the loose rich soil of which they were generally composed, together with the thickness of the timber, by preventing our falling, favoured our progress.  In the course of the afternoon I tried the angle of elevation and depression on various parts, and found it to be from 30 to 35 and even 40 degrees.  By the same means we found that the mountain which we had descended yesterday evening exceeded four thousand seven hundred feet in height on those angles.  The mountain we shall have to ascend to-morrow is very considerably higher; but, with one or two exceptions, the ascents are not so abrupt.  After the provisions were brought up, all hands were sent to cut a road for the horses through the brushes which surrounded the bottoms of the steepest ascents, and without which it would have been impossible for them to pass laden; the vines which crossed each other in various directions forming an almost impenetrable barrier.  It may seem superfluous to speak of soil and timber among such mountains as these; yet I will say that except where the rocks presented a perpendicular face, and along the highest ridges, the soil was light and good.  The timber consisted of blue gum and stringy bark, and forest oak [Note:  Casuarina torulosa.] of the largest dimensions:  the gorges of the valleys were covered with loose small stones, and in those gorges all the
