He was so intent on the prospect of a feast off the dead guanaco that he did not see us.  He crawled up near it, and then sprang on the carcass. We did not like to have our game destroyed, so we could not help shouting out, "Get off from that, you beast!"  Our voices startled the puma, and looking round and seeing us, and Surley approaching with an angry growl, he trotted off down the mountain.  We agreed that he was probably an old fellow, and that, having lost his activity, he could not catch the live animals.  We both fired, but we were not near enough, and missed him.  Away he bounded down the mountain without once stopping to look behind him.
