On emerging from the forest I found the adjacent plain covered with cattle quietly grazing. Any attempt to pass through the herd would have been almost certain death, as these more than half-wild beasts will always take revenge on their master man when they catch him dismounted in the open. As they were coming up from the direction of the river, and were slowly grazing past the wood, I resolved to wait for them to pass on before leaving my concealment. I sat down and tried to be patient, but the brutes were in no hurry, and went on skirting the wood at a snail's pace. It was about six o'clock before the last stragglers had left, and then I ventured out from my hiding-place, hungry as a wolf and afraid of being overtaken by night before finding any human habitation. I had left the trees half a mile behind me, and was walking hurriedly along towards the valley of the Yí, when, passing over a hillock, I suddenly found myself in sight of a bull resting on the grass and quietly chewing his cud. Unfortunately the brute saw me at the same moment and immediately stood up. He was, I think, about three or four years old, and a bull of that age is even more dangerous than an older one; for he is quite as truculent as the other and far more active. There was no refuge of any kind near, and I knew very well that to attempt to escape by running would only increase my danger, so after gazing at him for a few moments I assumed an easy, unconcerned manner and walked on; but he was not going to be taken in that way, and began to follow me. Then for the first, and I devoutly hope for the last, time in my life I was compelled to resort to the gaucho plan, and, casting myself face downwards on the earth, lay there simulating death. It is a miserable, dangerous expedient, but, in the circumstances I found myself, the only one offering a chance of escape from a very terrible death. In a few moments I heard his heavy tramp, then felt him sniffing me all over. After that he tried unsuccessfully to roll me over, in order to study my face, I suppose. It was horrible to endure the prods he gave me and lie still, but after a while he grew quieter, and contented himself by simply keeping guard over me; occasionally smelling at my head, then turning round to smell at my heels. Probably his theory was, if he had one, that I had fainted with fear at the sight of him and would recover presently, but he was not quite sure at which end of me returning life would first show itself. About once in every five or six minutes he seemed to get impatient, and then he would paw me with his heavy hoof, uttering a low, hoarse moaning, spattering me with froth from his mouth; but as he showed no disposition to leave, I at last resolved to try a very bold experiment, for my position was becoming unendurable. I waited till the brute's head was turned from me, then worked my hand cautiously down to my revolver; but before I had quite
