"Castro," said I, "we carry bad news, and bad news flies apace. Let us keep up the reputation of the old proverb. Half an hour or so may make all the difference in the world." He made a grimace as if to say that a few minutes more or less would matter little; but he saddled his horse promptly, nevertheless, and was ready to start as soon as I. "I reckon," he said, "that we may strike the road from Tacna to Arica by midnight to-morrow, unless our animals founder by the way. Can you trust your horse?" "The colonel selected him." "That ought to be sufficient warrant. The chief knows a horse, though he will ride in the absurd English style." There were few men in the country who would have cared to cut themselves adrift as Castro did on this ride of ours to intercept the marching Patriots. His only guides were those he could interpret from nature. While daylight lasted, he steered by the sun; at night, by the stars and the faint wind that fanned our faces. For twenty-four hours, during which time we rested, of course, both for our own sakes and for the sakes of our animals, not one human being crossed our path, or even came within sight of us. And during that time, also, we saw neither bird nor beast, nor any manner of living thing, save only ourselves and our animals. And then, quite unexpectedly to me, we came upon an oasis in the dreary desert--a little hamlet with mud-walled hovels, but better than those at Ilo, and having patches of cultivated ground enclosed. The natives had reclaimed this piece of land by means of the waters of a moderate-sized stream, and lived in almost as great isolation as if they had been on Robinson Crusoe's island. They were neither Patriots nor Royalists, and I doubt much whether they knew of the struggle going forward; but they had kind hearts, and gave us a warm welcome, pressing upon us gifts of fruits and vegetables to the limits of their scanty stock. They found ample forage, too, for the weary animals, and we stayed there a matter of three hours to rest Castro's horse, which had shown symptoms of breaking down. I seized this opportunity to snatch an hour's sleep; but my guide was kept chattering by the natives, who listened with amazement to his news. They knew no Spanish, and could not understand the native patois I spoke; neither could I understand a word of what they said. As for Castro, I suppose no man in South America had the gift of so many Indian dialects. "After all, lieutenant," exclaimed he, as we took leave of this simple community, "I doubt if these people have not the best of life. They eat, drink, and are at peace, caring no more for a president than for a king." "And doing nothing for either," I replied, laughing. "How does the horse seem now?" "I think he will do this journey. But if I'm to ride with the colonel, he will have to provide me with another."
