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 of 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!" We began to retreat, but before we were again under cover the dogs joined us; and, in spite of our shouts and efforts to restrain them, they dashed forward and seized a buffalo calf. This was a signal to the whole herd to attack us. They bellowed loudly, pawed the ground, and tore it up with their horns, and then dashed madly toward us. We had not time to step behind a rock before the leader was upon us. So close was he that my gun was useless. I drew a pistol and fired. He fell dead at my feet. His fall checked the advance of the rest. They halted, snuffed the air, turned tail, and galloped off across the plain. They were gone, but the dogs still held gallantly to the calf. They dragged and tussled with him, but with their utmost efforts they could not bring him to the ground. How to assist them without shooting the poor beast I knew not; and this I was unwilling to do, for I hoped that, if we could but capture him alive, we might in time manage to tame him, and use him as a beast of burden. Jack's clever little head, however, suddenly devised a plan for their aid, and with his usual promptitude, he at once put it into execution. He unwound the lasso, which was coiled round his body, and, as the young bull flung up his heels, he cast, it and caught him by his hind legs. The noose drew tight, and in a twinkling the beast was upon the ground. We fastened the other end of the cord round a stout bamboo, called off the dogs, and the animal was at our mercy.
