Fleming and his old shipmate, Tom Carver, kept spinning their interesting yarns about Lord Cochrane's gallant deeds till a late hour. At last it was time to go to sleep; so we wrapped ourselves up as closely as we could in our cloaks, with our feet to the fire and our backs to the rock, to seek repose.  Fleming, and Tom, and the doctor, however, kept watch one after the other, both to keep up the fire and to prevent our being taken by surprise by the visit of a puma, or any other unwelcome visitor.  By-the-by, the doctor told us that the puma very seldom seeks his prey in the day-time, or attacks men, though he has been known to do so at times.  The fellow we killed measured fully five feet from the nose to the tail, which was itself, in addition, two feet and a half long.  The back was of a brownish-red colour, and the breast of a reddish ash colour, and the lower jaw and throat white.  Its face was like that of a huge cat, and it is said to be able to climb trees, and to drop down from them on its prey.  Its ordinary way of seizing its prey is to spring on the back, and draw back the head of the animal till its neck is broken.  The guanaco, which is common throughout South America, was used by the ancient Peruvians, in great numbers, as a beast of burden.  It carried about a hundredweight.  Its flesh also served them for food; of its skin leather articles were made, and its hair was woven into cloth.  When domesticated, it is known as the llama.  It feeds on vegetables, and requires no attention.  Its voice resembles the shrill neighing of a horse.  Its use as a beast of burden has been superseded by the horse, the ass, and the mule.  The fleece of the tame animal is not so long as that of the wild one.  Their appearance I have already described.  I shall never forget that night among the Andes,-- how the stars of the southern hemisphere came out, and shone with a brilliancy I had never before seen in that purest of pure atmospheres, among those grand old mountains.  For a long time I could not go to sleep: at last I did, and it seemed but a moment afterwards that Terry aroused me to go with Tom and the Indian guide to bring the guanaco and the skin of the puma.  With their aid we were not long in finding the puma, and in having his skin off him.  We found the first guanaco untouched, so we took his skin and some of the flesh.  As, however, we were looking for the spot where we had left the other, a huge condor rose into the air, followed by two or three others.
