We did indeed, but they were of a terrible and most unexpected nature. Immediately beneath the cliff there grew a considerable patch of high bamboo, like that which we had traversed in our journey. Many of these stems were twenty feet high, with sharp, strong tops, so that even as they stood they made formidable spears. We were passing along the edge of this cover when my eye was caught by the gleam of something white within it. Thrusting in my head between the stems, I found myself gazing at a fleshless skull. The whole skeleton was there, but the skull had detached itself and lay some feet nearer to the open.
