Towards the end of the next week, Henriquez said he should like to ride over and visit a friend who lived at a small native place on the other side of Guaycoru. So it was arranged he should go on Saturday morning, returning home on the Monday, and that I should keep an eye on the flock of sheep. They did not feed far distant from the house, and when once turned early in the afternoon, usually fed quietly on their way home. So on Saturday morning after coffee, Henriquez caught and saddled up his chestnut, putting on his best gear, and wearing a clean white shirt, a black jacket and waistcoat, and a pair of black "merino bombachos," or wide trousers, tucked inside a pair of carefully polished long boots. On these he buckled a pair of silver spurs, of which he was very proud, as also of the handsome silver buttons fastening the wide belt of carpincho skin he wore round his waist. Finally he put on his summer poncho, a very nice one, and a soft broad-brimmed felt hat completed his appearance, which seemed to give him every satisfaction. Just before mounting his horse he examined his revolver, which he carefully fixed in its proper place inside his belt. I rode with him for about half a mile, and the last I saw of him was as he turned round the corner of a large grey mass of rock which bordered the track, and so disappeared from view. He did not return on the Monday as expected, and on the Tuesday morning when the boy drove up the riding horses to the corral, much to our surprise his chestnut was among them, with a bit of broken hide hanging loosely down from where it was fastened round the horse's neck. We supposed, however, it had been collared to a mare where Henriquez was staying, as was a usual custom, and had broken away during the early part of the previous night, and so found its way home. However, both Tuesday and Wednesday passed and he did not return, as we felt quite sure he would do, on a horse borrowed from his friends. So on Thursday morning I started to ride over to the place where Henriquez had gone, and during my absence the boy was to watch the sheep. Arriving there, as I did, about nine o'clock, my surprise may be imagined when I was told that Henriquez had left them about two o'clock on the Monday afternoon, quite well, mounted on his own horse, and that he seemed anxious to reach home with as little delay as possible. I stayed about half an hour discussing the situation, and then started to ride to the pulperia at Guaycoru, to make further enquiries. When I got there the owner knew nothing, nor had he heard anything regarding Henriquez from anyone who had come to his pulperia. He was a kind little man, and much concerned at my news, and he promised to enquire from anyone who called at his house if perchance they might have seen Henriquez, or heard any news of him. I stayed a little while and got some coffee and two or three biscuits, and then remounted a big brown horse I was riding, somewhat
