The work made good progress, so that we were both back again at the Cerro a little before twelve o'clock. When I saw Correo he told me a Swiss baker had called during our absence, on his way outside with bread, and that he had bought three loaves from him. We were glad of this, as being a pleasant change from the "galleta," or hard camp biscuit. According to our usual custom, we were both again up on the "azotea" about four o'clock in the afternoon. Everything seemed quiet, but we had not been there long before our attention was arrested by what looked like a covered cart slowly crossing the camp, about a mile and a half away, in the direction of the Canyada Grande, opposite to Laborde's puesto. Every now and again it seemed to stop, and the two horses, which we could see were drawing it, appeared to be grazing. Altogether, it gave us the impression that either there was no driver in the cart, or that if one was there, he was either drunk or incapable. I then decided to send Justiniano to see what was the matter. He had the bay colt his uncle had tamed saddled, whose shoulder was even yet not quite sound. I told him if he found anything wrong to make his lasso fast to the horses, and so bring them cart and all, up to the Cerro. By this time, from Correo's description, we had identified the cart as belonging to the Swiss baker, who had passed in the morning. Of course, it was possible that he had somehow got separated from his cart, which was now moving towards home without him. Meanwhile, we watched Justiniano reach the cart, get off his horse, and go round to the back to look in behind. He then came round and made fast his lasso to the horses' heads, remounted, and made start with the cart in tow in the direction of the Cerro. All this we could see quite clearly through the telescope. When he arrived, I went down to meet him, and Correo and Pedrito and uncle Juan were all in attendance. I saw at once from Justiniano's countenance, that something serious had happened. Our consternation may be imagined when he told us that the body of the baker was lying inside the cart, and that he was quite dead, with his throat cut from ear to ear. How he had come to his death we were unable to form any idea. We could only suppose that two or three "matreros" had come across him in the open camp, far from any dwelling, and that they had done the dastardly deed from sheer devilry. The poor man apparently had no revolver or weapon with him in the cart; if he had one it had been taken away, neither was there any sign of shots having been fired at him; nor was either of the horses in any way maimed or injured. In fact the whole thing was a complete mystery. Correo and the Indians seemed greatly impressed. Naturally, the former could identify the body and the cart as being that of the man from whom he had bought the three loaves of bread in the morning, but beyond that there was nothing whatever to point as to how the tragedy had come about.
