The day following, we were in an open country. We had passed over the hills, and travelled through plains, filled with calcined flint-stones, which resembled smith's charcoal. Above these stones, arose at a little distance, a whitish earth, upon which we saw great trunks of trees, heaped upon one another, the roots of which were torn off. The bark was entirely stripped off, and the branches, brittle as glass, were twisted like cords. The wood was of a yellowish colour, like the wood of liquorice, and besides, the inside of these trees was filled with a powder, very hard to the touch. All this announced to me a very extraordinary revolution. I was anxious to learn, if these trunks had any taste of sulphur; but neither the wood, the dust enclosed in the heart of the trees, nor the calcined stones, had either taste or smell.
At some distance, we found the mountains of a prodigious height, appearing as if they were piled one above another. The rocks, which were detached, had formed, by their crumbling down, as it were precipices. Others, suspended in the air, threatened to crush in pieces the traveller below. Others, again, in their striking one upon another, by receiving in their shock, slimy earth, which hurled down continually, formed frightful caverns. The surrounding valleys were filled with rocks, which appeared to rise one above another, and produced new masses, not less frightful. To conclude, it appeared like a long range of mountains, from which pieces of a great size were frequently falling, which were reduced to dust, before they reached the ground.
From another side issued two fountains, one of which drew along with it, in its course, a black slimy stuff, which occasioned a sulphurous smell. The other, separated from the first, by a small isthmus of sand, from twelve to fifteen paces broad, is clearer than crystal. The taste of these waters is pretty agreeable; the bottom of their bed is filled with small stones of various colours, which presented to the eye a delightful prospect.
It was in the same place I observed a singularity, which I submit to the understanding of my readers. In a valley, which appeared at first sight, to be very much circumscribed by the number of surrounding mountains, across threatening vaults, formed by the falling of different rocks, heaped upon one another, I discovered an immense region, which astonished me by the variety which it presented to our view. At the first entrance of this valley, the ground is moist and furrowed, as if rivulets had formerly winded through it. The borders of these furrows were covered with many beds, and thickly spread over with a nitrous kind of ice. The rocks, which served to enclose them, were covered with the same, and had a near resemblance to cascades. The thick reddish roots, and the branches, covered with leaves, like those of the laurel tree, crept across the different crevices. At a greater distance, on advancing towards the west, we saw pyramids of great stones, as white as alabaster, towering one above another, which seemed to indicate the border of a bank, and above which very high date-trees grew up, of which the trunks were warped round even to the top. The palm trees, extended upon a mass of stones, by their length and colour, gave proof of their antiquity. Others, lying across here and there, and wholly stripped of their bark, afforded a very dismal spectacle.
I split one of the palm-trees with my nails, and put a piece of it in my mouth; it had a taste, at once bitter and salt, but no smell. Those which were overturned, fell in pieces immediately upon my touching them; and the filaments which remained under the bark, were covered over with a saltish powder, as clear as crystal. The roots which hung far down from the rocks were glutinous, and the bark broke off with the least touch. I plucked up several branches of wild laurel, from which I immediately distilled some white drops, one of which, having fallen upon my hand, occasioned a very smart pain, and a black spot, which took off the skin. I durst not venture to taste it. In a word, the stones, the nitrous beds, the overturned date-trees and others, enveloped to the very top the immense plain covered with an extremely fine salt, the ground cut and furrowed, which appeared to have been turned up by the torrents, those rent mountains, if I may use the expression, all seemed to indicate, that at some former period, the scum of the sea had been carried into these places. I asked at Sidy Sellem, if we were far from the sea, and if ever it had passed that way? He told me, that we were perhaps the first of the human race who had landed there; that he was looking for the sea, which ought to be before us, in order to discover the places where, he had been told, some Arab camps were to be found, among whom he had friends who had accompanied him in a journey to Mecca.
"Keep yourself easy," added he, "the sun is my guide, he will conduct me where I wish to go. You may therefore follow, without fear, the footsteps of the camels." Indeed, I thought that I walked with considerable ease; but it was not long, when I began to feel excessive pain, as my feet, severely torn, were filled with a kind of saltish dust. How greatly was I astonished, when, after two days' travelling, I found we were on the brink of the sea, and perceived below me the rolling waves foaming upon a frightful precipice! Towards the east, where I then was, its course was limited by immense rocks. On considering this elevation, I could not persuade myself, that ever this element had carried its waves to such a height. The rocks, said I to myself, would then serve for a bed to it. I lost myself in my conjectures;—besides, I set out at first to report facts, and it is not my province to make learned dissertations.
After some days journey farther, gradually advancing towards Morocco, we found other mountains no less elevated than the first, covered with stones of rose, violet, citron and green colours, and I observed extensive forests at a distance. I had not seen any before all the thirteen months I had been in the deserts. I was astonished to see the trunks of trees coming out of the centre of rocks, and to appearance hanging down like fruits. I saw with surprise also the roebucks running after one another, upon these same trees, leaping on the hanging rocks with incredible velocity, when they perceived any one following them. The moment one of them took to flight, the rest immediately followed. I observed, among many other trees, that of which the leaf resembled the gum-tree, or our parsley, to be the only one of the different kinds which I had seen, in all these countries, that had suffered from lightning. The thunder had no influence upon the rest.
We travelled through the forests for three days. We had spent already four nights, and, during that time, had not heard any thing of the fierce animals, with which the deserts of Africa are overspread. They must certainly inhabit the country which lies far to the eastward; but how do they procure water?
The more we advanced, the more my distress abated. We frequently found fields of barley ready to be reaped. I sat down and ate, with a degree of pleasure which I cannot express. The water now also became more abundant. On every side, we frequently fell in with villages, where we were well received. In others, where we would not have been so safe, Sidy Sellem was much respected, as he had formerly made a journey to Mecca. However, the Arabs of the tribe of Telkoennes exceeded all in their attention to us.
After having paid Sidy Sellem all the customary honours due to a stranger, they caused to be set before him, at the usual hour, barley, meal, and milk. He gave me the remainder of his supper, which I went to eat apart with my new comrade the baker; for, especially on a journey, a Christian ought neither to eat nor drink, and far less to sleep, beside his master. My repast being ended, I dug a hole in the sand, in order to screen myself from the cold. To prevent the sand from entering into my eyes, I covered my head with a piece of packing-cloth, which I wore about my middle. But I had scarcely closed my eyes, when I heard the report of two gunshots, which appeared to have been fired hard by me, and immediately I was seized by the body. I very readily threw off me the covering of sand which I had made myself, and which was warm. One of those who held me, asked me if I was wounded. I supposed that the fire, which had taken hold of my linen, had come from the wadding of the gun. "No," replied I, "but on what account do you treat me in this manner?"—"Sir,"[30] answered he, "follow us." My master, who had been awakened by the report of the gun, ran towards the place where he had heard my voice. He complained of their abusing in such a manner one of his slaves, and that they had violated the laws of hospitality towards such a man as he was. The Arab of the mountains, in reply, told him, with an imperious tone, that during the night he watched his flock, not knowing that I belonged to his retinue; and having seen a man conceal himself in the sand, he had supposed him to be one of those robbers, who, during the night, come to carry off their young goats. Sidy Sellem pretended to believe him, commended his zeal, and took me out of his hands. As soon as he imagined that the village was all quiet, he left a place where he was as much afraid of his own safety as mine.
