Up early, and after a hearty breakfast of deer-steaks, started for the caves of Sirih. We passed up the street that runs through the centre of the village, the houses looking very dilapidated in comparison with those of the Sibuyau Dayaks, but all were swarming with children. An abrupt descent brought us to a lower part of the stream that runs at the foot of Munggu Babi, affording beautifully clear water for the villagers. Continuing our course over the low buttress of the Sadong mountains, where the Dayaks have enclosed several spots for gardens, we had a beautiful prospect of the surrounding country, better seen however from the heights above, which we intended passing over the next day. Two miles’ walk through old farms and fresh felled jungle brought us to the foot of a very steep hill in which the cave was situated. Clambering up the rocks for a couple of hundred feet, we suddenly found ourselves at the mouth of the cave. The entrance is peculiar: divided formerly into three, the fall of a pillar has united two of the openings into one, which is above thirty feet in breadth; at first there appeared no far interior, but to the left a descending passage led into the great cave. To the right was a separate apartment with a fine opening, forming the first division of the mouth, but inaccessible from the outside. The Dayak boys beckoned us to come in. We went, thinking they wished us to look out from thence on the beautiful valley below and the lofty mountain beyond it; but our surprise was great when they pointed into a deep hole where lay the skeleton of a human being.
