Started at day-break from San Luis, to go to the Gold Mines and Lavaderos of La Carolina, which are in the mountains on the north of the town.

Drove a set of loose horses before us, and, about twelve o'clock, stopped to change.

The horses were driven to the edge of a precipice which was quite perpendicular, and which overhung a torrent, and we formed a semicircle about them while the peons began to catch them with the lasso, which they were much afraid of. The horses were so crowded and scared, that I expected they would all have been over the precipice: at last the hind-legs of one horse went down the cliff, and he hung in a most extraordinary manner by the fore-legs, with his nose resting on the ground, as far from him as possible, to preserve his balance. As soon as we saw him in this situation, we allowed the other horses to escape, and in a moment the peon threw his lasso with the most surprising precision, and it went below the animal's tail like the breeching of harness. We then all hauled upon it, and at last lifted the horsey and succeeded in dragging him up: during the whole time time he remained quiet, and to all appearance perfectly conscious that the slightest struggle would have been fatal to him.
