"And be put in irons! Perhaps you think that's a subject for cheerfulness?" "We shouldn't be able to risk our lives again, at all events." "Oh, go to sleep," exclaimed Alzura, "if you've nothing more sensible than that to say!" and he rolled a little nearer the fire. The next morning the Indians resumed their journey, and after a weary tramp of many miles, encamped on the side of a mountain, where stood several huts in a half-ruined state. One of these was set aside for us, and a sentry was placed at the door. Here we remained for three weeks while our captors made frequent excursions, starting early in the morning and returning late at night, though of their object we had not the faintest idea. At the end of that time we were taken with them; and from morn till night, for several days in succession, we roamed about those dreadful mountains, till every muscle in our bodies ached with fatigue. "What is the use of it all?" I asked Alzura gloomily. "What do they expect to gain by this continual tramp up and down?" "It's my belief that they can't help themselves," he replied. "It's a disease, a form of madness, which keeps them continually on the move. Yesterday we climbed the same hill a dozen times, and finished at the starting-point. Or perhaps it's some new kind of warfare they've invented." "It's awfully ridiculous, anyhow, and I don't see that we've gained much by leaving the island--unless it's exercise." "When the war is over, I'll give up walking altogether," said my chum resolutely. "When I'm not on horseback, or in a carriage of some kind, I'll be carried about in a chair. If this lasts much longer, my feet will be worn out." That evening the Indians lit their fire earlier than usual--a circumstance for which we were duly grateful. We ate our supper, and sat chatting together cheerfully, being put in good humour by the warmth and brightness of the ruddy flames. Suddenly we heard in the distance the long-drawn-out note of a night bird, repeated again and again, and each time nearer to us. It was answered by our sentries; but the men round the fire made no movement, nor did they show the slightest interest when half a dozen horsemen rode up. The leader, however, rose slowly and talked to the strangers, who, after seeing to their horses, came and sat down. "Juan," said Alzura, "these fellows belong to a different tribe. Perhaps we shall have a chance of making ourselves understood." "They are looking at us very pointedly," I answered; and raising my voice, I said, "Can any of you talk Spanish?" "Yes," cried several together, coming near to us; "what do you want?" "To make ourselves known," I replied. "These worthy fellows can't understand us, and we're tired of playing hide-and-seek in the mountains." "Who are you? Where do you come from? Are you for the king?" asked one.
