But God still had pity on me, and inspired me with the thought of going to the river, which lost itself in the hollow of the cave. I examined it with great attention, and it occurred to me, that as the river ran under ground, it must in its course come out to day-light again; if I construct a raft, thought I, and place myself on it, the current of the water may perhaps bring me to some inhabited country; if I perish, it is but changing the manner of my death; but if, on the contrary, I get safely out of this fatal place, I shall not only avoid the cruel death by which my companions perished, but may also meet with some fresh opportunity of enriching myself. Who knows, that fortune does not await me on my arrival out of this frightful cavern, to recompense me for all the losses I have sustained.

I worked at my raft with fresh vigour after these reflections; I made it of thick pieces of wood and great cables, of which there was an abundance; I tied them closely together, and formed a strong vessel: when it was completed, I placed on it a cargo of rubies, emeralds, ambergris, crystal, and also some gold and silver stuffs. Having placed all these things in a proper equilibrium, and fastened them to the planks, I embarked on my raft with two little oars, which I provided myself with, and trusting to the current, I resigned myself to the will of God.

As soon as I was under the vault of the cavern I lost the light of day; and the current carried me on without my being able to discern its course. I rowed for some days in this obscurity, without ever perceiving the least ray of light. At one time the vault of the cavern was so low, that it almost knocked my head, which rendered me very attentive to avoid the danger again. During this time I consumed no more of my provisions than was absolutely necessary to sustain nature: but however frugal I might be, I consumed them all. I then fell into a sweet sleep. I cannot tell whether I slept long, but when I awoke I was surprised to find myself in an open country, near a bank of the river, to which my raft was fastened, and in the midst of a large concourse of blacks. I rose as soon as I perceived them, and saluted them; they spoke to me, but I could not understand their language.
