A bright morning awoke us early, and I rose and looked out, thinking that perhaps our poor donkey might have been attracted by the light of the fires, and have returned. Alas! not a sign of him was to be seen. As we could not afford to lose so valuable a beast, I determined to leave no attempt untried to regain him. We hurriedly breakfasted, and, as I required the dogs to assist me in the search, I left my elder sons to protect their mother, and bade Jack get ready for a day's march. This arrangement delighted him, and we quickly set out. For an hour or more we trudged onward, directed by the print of the ass's hoofs. Sometimes we lost the track for a while, and then again discovered it as we reached softer soil. Finally this guide failed us altogether, for the donkey seemed to have joined in with a herd of some larger animals, with whose hoof-prints his had mingled. I now almost turned back in despair, but Jack urged me to continue the search; "For," said he, "if we once get upon a hill we shall see such a large herd, as this must be, at almost any distance. Do let us go on, father." I consented, and we again pushed forward, through bushes, and over torrents, sometimes cutting our way with an ax, and sometimes plunging knee-deep through a swamp. We at length reached the border of a wide plain, and on it, in the distance, I could see a herd of animals browsing on the rich grass. It struck me that it might be the very herd to which our good donkey had joined himself; and, wishing to ascertain whether this was so, I resolved to make a detour through a bamboo marsh, and get as near as possible to the animals without disturbing them. The bamboos were huge, many of them over thirty feet in height; and, as we made our way through them, I remembered an account of the giant cane of South America, which is greatly prized by the Indians on account of its extreme usefulness; the reeds themselves make masts for their canoes, while each joint will form a cask or box. I was delighted, for I had little doubt that the bamboos we were among were the same species. I explained this to Jack, and as we discussed the possibility of cutting one down and carrying a portion of it home, we reached the border of the marsh, and emerged upon the plain. There we suddenly found ourselves face to face with the herd which we sought--a herd of buffaloes. They looked up and stared at us inquisitively, but without moving. Jack would have fired, but I checked him. "Back to the thicket," I said, "and keep back the dogs!"
