many curious articles in clay and obsidian, which we bought and deposited in two great bags of aloe-fibre which our man carried at his saddle-bow. Among the articles we bought were various pipes or whistles of pottery, pitos, as they are called in Spanish, and just as we were mounting our horses to ride off, a lad ran to the top of one of the mounds, and blew on one of these pipes a long dismal note that could be heard a mile off. Our friends had filled our heads so full of robbers and ambushes, that we made sure it was a signal for some one who was waiting for us, and the more so as the boy ran off as soon as he had blown his blast; and when we looked round for the people whose antiquities we had been buying, they had all disappeared.

Inside the house, pour surcroît de précaution, a servant came round to see that every one was in his room; and having satisfied himself of this, let loose in the courtyard two enormous bulldogs, which were the terror of the household and of the whole neighbourhood. On this particular night, a noise at our own door woke me from a sound sleep; and
