We were not fortunate in the time of our visit, as most of the people were away preparing their farms. We took up our residence in the head-house, which, however, was destitute of the usual ornaments. It was quite new. All head-houses have the same appearance, being built on high posts above the ground, and in a circular form, with a sharp conical roof. The windows are, in fact, a large portion of the roof, being raised up, like the lid of a desk, during fine weather, and supported by props; but when rain or night comes on, they are removed, and the whole appearance is snug in the extreme, particularly when a bright fire is lit in the centre, and throws a fitful glow on all the surrounding objects. Around the room are rough divans, on which the men usually sit or sleep, but that night, there being a cold wind and a drizzling rain, a good fire was kept up, and the people crowded near. I awoke at about two, and put my head out of my curtains to look at a night-scene: a dozen of the old men were there collected close over the fire, smoking the tobacco we had given them, and discoursing in a low tone about us. The flames occasionally shot up brilliantly and showed me the curious group, and then, as they faded away, nothing but the outlines of the half-naked old men could be seen cowering over the embers, as a ruder blast or a heavier shower brought the cold wind upon them. Started early in the morning. The limestone rock, undermined in every direction, was worn into very singular shapes. Occasionally the tall trees, finding insufficient support, had broken from the bank, and slipped their roots into the river, to be completely washed away by next flood. At ten, brought up on a pebbly beach for breakfast, opposite a little cave, about which the Dayaks have as usual a story--this time an indelicate one. Continuing our course, we reached the mountain of Rumbang, remarkable for its curious caves. We had brought guides with us from San Pro, and stopping at the nearest point went ashore, and after a walk and climb of a few hundred yards, reached the entrance of the first cave. Descending over a few rough stones, we found ourselves in the interior, through which a small stream makes its way. Having lighted a candle and a torch, we advanced--now fording the brook, now jumping over it: the floor is principally pebbly, though occasionally we met with soft sand and slippery rock. The cave itself has no remarkable feature, but is nevertheless interesting. Its height varied between thirty, forty, and fifty feet--its exit beautiful in rugged feature in a soft light, which subdued the uncouth shapes of the rocks, and rendered them striking and pleasing to the eye. This we particularly noticed on our return, when we approached the entrance. Then the light played on the surface of the stream, as it bubbled onward in its course, and the reflection slightly illuminated the surrounding features, reminding me of a robber’s cave in a dissolving view.
