Having remained eight days at Siwah; on the 29th of September, at three in the afternoon, we broke up our encampment, and proceeded a three hours march, when we again pitched our tents at foot of a hill. The next day we began our journey late, being delayed till one o’clock, in search of a slave who belonged to a court-officer of the Sultan of Fezzan, and who had absconded from the caravan. Whilst the man was looking for, I set out with a view of inspecting some catacombs which I descried on the neighbouring hills, but was stopped at some distance by a lake of seven or eight miles in circumference, formed at the base of the mountain by the conflux of springs and small pools of water, which the rains at this season had swollen and brought together. Returning to the camp, I took my telescope to examine the appearances I was not enabled closely to inspect, when the first object on the mountain which presented itself to my view was the Negro after whom the search was making. I gave no notice of my discovery, the poor fellow having a good character, and having been driven to the attempt of flight by the extreme severity of his master. I am sorry to say there was little hope of his final escape, the Siwahans having promised to deliver him up. This day we travelled till half an hour after sun-set. The next day we marched at two hours before day-break, and halted at nine. The fourth day brought us to the fruitful valley of Schiacha.

The mountains by which we travelled from Siwah to this spot, are branches of those which I have mentioned as appearing, at all times, to north of our way through the Desert, and often at but little distance. They rise abruptly, and as precipices, from the level ground, and shew a face of mere rock, without the least covering of soil or even of sand. Their appearance, taken together with that of the sea-sand which covers the Desert, indicate this vast tract to have been flooded, and at a period later than the great deluge. In the sandy plain below these mountains is seen the surface of a vast calcareous rock, containing no substance of petrifaction, whereas the mountains near consist of limestone, crowded and filled with fragments of marine animals and shells. The strata of all these rocky hills lay horizontal.

Westward of Siwah, I found two banks or heaps of calcined shells, some of the size of two inches over. My interpreter told me, that taking his road at some distance from me, he saw a mountain standing singly and unconnected with others, composed entirely of shells. Many such vast isolated mounds are to be seen throughout the whole of this district, and the bed-joints or interstices of their strata of stone (always horizontal), being filled up with a reddish, friable, calcareous substance, they often resemble pyramids, and in so exact and illusive a manner, that more than once I was deceived into expectation of arrival at such building. The architecture of the ancient Egyptians was of the vast and gigantic kind; and builders of such ambitious temper and stupendous scheme, might readily entertain the idea of transforming a mountain into a pyramid, shaping the huge rock, already in form partly adapted, and casing it with wrought stones on the outside, as they might prefer. Some of the learned have given an opinion, that the Pyramids of Giza and of Saccara, were not originally erections from the base, but merely hills of earth or stone, shaped and covered by the labour of man. The idea is plausible, though certainly to be controverted, by reasons to be drawn from history, and from other the best sources of fact and argument.

I now proceed to the recital of an event in which I was personally and principally concerned. I shall give the recital in detail, as, in its consequences, being of the highest import to the future safety of myself, and therewith to the progress of discovery which I have engaged in; and, as it has afforded me self-confidence and new encouragement, ever favourable to the success of enterprize, so will it, I trust, give satisfaction to those who have employed me, inspiring just and well-founded hopes of my finally accomplishing the great purpose entrusted to my care.

The state of quiet and security usually attending our encampments was interrupted, whilst at Schiacha, by the arrival of some Siwahans, who, about eight o’clock in the evening, came with intelligence, that a numerous horde of Arabs from the vicinity of Faiume were hovering in the Desert, ready to fall upon our caravan. These messengers at the same time assured us, that the people of Siwah had resolved to come to our assistance, and to escort us to the next watering-place; adding, “that their little army would arrive in a few hours, determined to risk with us every thing in opposing the attack of the Bedouins, whose force they represented as consisting of from 800 to 1000 men. Our leader, the Sheik of the Twaters, immediately assembled the principal people of the caravan, when it was decided not to desert our post, but to await the enemy. Scarcely was our little council broke up, when we heard from afar the braying of some hundred asses, giving notice of the approach of the Siwahans. They use this animal on their military excursions, from the advantage it affords of more easily proceeding by narrow and rugged passes among the mountains, and evading or attacking any enemy, who from ignorance of the country, or from the nature of its cattle requiring safer roads, is obliged to confine its march to broader defiles or vallies. Some men were immediately dispatched from the caravan, requiring the Siwahans to halt at half a mile distance from our post. The night passed in disquietude and alarm: each got his arms in readiness, and prepared for a battle on the ensuing day. A little before sun-rise, the Siwahans advanced on foot, and gave apprehension of immediate attack. Some Augilans rode forward, to inquire their intentions, and were answered, “that the caravan had nothing to fear;” on reporting this to the Sheik, he sent the messengers back, to say he should consider and treat them as enemies, if they advanced a step further. On this message the Siwahans halted, formed a circle, and invited some Augilans to a conference. During all this time, I remained quiet with my baggage, having sent my interpreter to collect intelligence of what was passing. Seeing him return, and judging from his manner and haste, that he had something of importance to communicate, I ran to meet him. He immediately accosted me with, “cursed be the moment, when I determined upon this journey; we are both of us unavoidably lost men; they take us for Christians and spies, and will assuredly put us to death.” With these words he left me, and ran to the baggage, where he exchanged his single gun for my double barrelled one, and armed himself with two brace of pistols. I upbraided him with his want of firmness, told him “a steady and resolute conduct could alone preserve ourselves and friends, and reminded him that his present behaviour was precisely such as to give weight to the suspicions entertained:” I further urged, “that on his own account he had nothing to fear, having for twelve years been a Mahommedan, and perfectly acquainted with the religion and customs; that myself alone was in danger, and that I hoped to avert it, provided he did not intermeddle with my defence.” “Friend, (answered he,) you will never hear of danger: but this time you will pay for your temerity.”

Perceiving that terror had wholly deprived him of the necessary temper and recollection, I now left him to himself, and walked up unarmed, but with a firm and manly step, to this tumultuous assembly.

I entered the circle, and offered the Mahometan salutation, “Assulam Alckum,” but none of the Siwahans returned it. Some of them immediately exclaimed,—“You are of the new Christians from Cairo, and come to explore our country.” Had I at this time, been as well acquainted with Mahometan fanaticism, and the character of the Arabs, as I have been since, I should have deduced my defence from the very terms of the accusation, and stated that I was indeed from Cairo, having fled from the Infidels; as it was, I answered nothing to this general clamour, but sat down and directed my speech to one of the Chiefs, whose great influence I knew, and who had been often in my tent whilst at Siwah. “Tell me, brother, (said I,) hast thou ever before known 300 armed men take a journey of three days, in pursuit of two men, who dwelt in their midst for ten days, who had eaten and drank with them as friends, and whose tents were open to them all? Thyself hast found us praying and reading the Koran; and now thou sayest we are Infidels from Cairo; that is, one of those from whom we fly! Dost thou not know, that it is a great sin to tell one of the faithful that he is a Pagan?” I spoke this with an earnest and resolute tone, and many of the congregation seemed gained over by it, and disposed to be favourable to me: the man replied, “that he was convinced we were not Infidels, that he had persuaded no one to this pursuit, and as far as depended on him alone, he was ready to return to Siwah.” On this I turned to one of the vulgar, who was communicating some of the accusations against me to the people of our caravan. “Be thou silent, (said I,) would to God, that I were able to speak well the Arabic, I would then ask questions of thee, and of hundreds like thee, who are less instructed in the Islam than I am.” An old man on this observed, “This man is younger than the other, and yet more courageous!” I immediately continued, “My friend is not afraid of thee, but thou oughtest to have fears of my friend: dost thou know what it is to reproach a man, who lives with sultans and with princes, with being an Infidel?” I was then asked for what purpose we carried Christian papers. I now found that my interpreter had unwarily shewn a passport which I had obtained from General Bonaparte, with a view not to be detained at the French posts through which I was to pass to the caravan. My interpreter at this moment came up, and finding me alive, and the assembly less angry and violent, than when on being first questioned, he had exasperated them by inconsiderate and perplexed answers; he recovered himself, and stood sufficiently composed and collected, whilst I explained partly in German, partly in Arabic, what had passed. Knowing, however, that the paper in question would be demanded, and not choosing to trust to his prudence in the manner of producing it; I went myself for it to the tent, and returning, brought likewise a Koran with me. I immediately tendered the paper to a Chief of the Siwahans, who having unfolded it, asked, “if any by-stander could read it.” I could not help smiling at the question, perilous as was my situation. The same question was then put to us, when I answered, “that we did not understand what it contained, but were told, it would allow us to quit Cairo without being molested.” “This is the book, (interrupted my interpreter,) which I understand:” and immediately took the Koran from my hand. We were ordered, by reading in it, to give proof of our being truly of the religion. Our learning in this respect went far indeed beyond the simple ability of reading. My companion knew the entire Koran by heart, and as for me, I could even then write Arabic, and well too: which with these people, was an extraordinary proficiency in learning. We had scarcely given a sample of our respective talents, when the chiefs of our caravan, who to this moment had been silent, now took loudly our part; and many of the Siwahans too, interfered in our favour. In short, the inquiry ended to our complete advantage, though not without the murmuring of some in the multitude, who lost the hopes of plunder which the occasion might have afforded.

Thus the character of Mussulman which I assumed was firmly established, and I shall not be subjected in future, to like inquiries, on which, perhaps, more decisive proofs might be required, and which I could not give. The security of my future voyage is thus assured, and so great an advantage more than compensates for some losses attending the above incident, but which yet I must regret.

During the time I was first in conference with the people of Siwah, and those of the caravan, my baggage was left with my interpreter; who in the paroxysms of his fears, and indeed with no light apprehensions of our bales of goods being searched, took my remains of mummies, my specimens of mineralogy, my more detailed remarks, made on my way from Cairo to Schiacha, and generally my books, and gave them to a confidential slave of my Arab inmate, to bury them in a bog; this was done, and I never afterwards could retrieve them.
