but a goat or an Indian could have stood. One of these ropes was nearly thirty feet in length; our guides offered to help us up this pass, but rather recommended one lower down, a few hundred yards away, which was much less dangerous. We did not choose to venture on it, as the sight which was to reward our hazard was nothing but a grove of vae trees, such as we had often seen before.
In the whole course of this walk the rocks were almost constantly bare to the view, so that I had a most excellent opportunity of searching for any appearance of minerals, but saw not the smallest sign of any.

I have very little doubt of the former, especially, coming to perfection, as I have given away large quantities of seed among the natives; I planted some also in the woods. The natives now continually ask me for seeds, and have already shown me melon plants of their raising which
