When we had passed through this second valley, I perceived we came to a narrower passage, and something like the first; the entrance into it indeed was smooth, and above a quarter of a mile broad, and it went winding away to the north, and then again turned round to the north-east, afterwards almost due-east, and then to the south-east, and so to south-south-east; and this frightful narrow strait, with the hanging rocks almost closing together on the top, whose height we could neither see nor guess at, continued about three days' journey more, most of the way ascending gently before us. As to the river, it was by this time quite lost; but we might see, that on any occasion of rain, or of the melting of the snow on the mountains, there was a hollow in the middle of the valley through which the water made its way, and on either hand, the sides of the hills were full of the like gulleys, made by the violence of the rain, where, not the earth only, but the rocks themselves, even the very stone, seemed to be worn and penetrated by the continual fall of the water. Here my patron showed me, that in the hollow which I mentioned in the middle of this way, and at the bottom of those gulleys, or places worn as above in the rocks, there were often found pieces of gold, and sometimes, after a rain, very great quantities; and that there were few of the little Chilian cottages which I had seen where they had not sometimes a pound or two of gold dust and lumps of gold by them, and he was mistaken, if I was willing to stay and make the experiment, if we did not find some even then, in a very little search. The Chilian mountaineer at whose house we stopped to dine had gone with us, and he hearing my patron say thus, ran presently to the hollow channel in the middle, where there was a kind of fail or break in it, which the water, by falling perhaps two or three feet, had made a hollow deeper than the rest, and which, though there was no water then running, yet had water in it, perhaps the quantity of a barrel or two. Here, with the help of two of the servants and a kind of scoop, he presently threw out the water, with the sand, and whatever was at bottom among it, into the ordinary watercourse; the water falling thus hard, every scoopful upon the sand or earth that came out of the scoop before it, washed a great deal of it away; and among that which remained, we might plainly see little lumps of gold shining as big as grains of sand, and sometimes one or two a little bigger. This was demonstration enough to us. I took up some small grains of it, about the quantity of half a quarter of an ounce, and left my midshipmen to take up more, and they stayed indeed so long, that they could scarce see their way to overtake us, and brought away about two ounces in all, the Chilian and the servants freely giving them all they found.
