All the country from the banks of the river to the hills, a distance of about eight or nine miles, and the whole surface of this mountain range, is covered with brown iron-ore and aërolites; where they occur in the greatest abundance, vegetation is scanty and consists principally of bamboo, but it is rich and varied in those places where the detritus has formed a thicker surface of soil. The dense forests furnish gum and oil, which would be valuable for commerce if the indolent natives could be prevailed on to collect them. They are, however, infested with leopards, tigers, and tiger-cats. Two dogs and a pig were carried off from the immediate vicinity of the hut of the Christian guardians of our boat during our stay at Pakpriau; but the following day I had the pleasure of making the offending leopard pay for the robbery with his life, and his skin served me for a mat. Where the soil is damp and sandy I found numerous traces of these animals, but those of the royal tiger are more uncommon. During the night the inhabitants dare not venture out of doors; but in the day-time the creatures, satisfied with the fruits of their predatory rambles, skulk into their dens in the recesses of the woods. One day I went to explore the eastern part of the chain of Pakpriau, and, becoming excited in the chase of a wild boar, we soon lost ourselves in the forest. The animal made his way through the brushwood much more easily than we could--encumbered as we were with guns, hatchets, and boxes--and we ere long missed the scent. By the terrified cries of the monkeys we knew we could not be far from some tiger or leopard, doubtless, like ourselves, in search of prey; and, as night was drawing in, it became necessary to retrace our steps homeward for fear of some disagreeable adventure. With all our efforts, however, we could not find the path. We were far from the border of the forest, and were forced to take up our abode in a tree, among the branches of which we made a sort of hammock. On the following morning we regained the river.
