we learnt that slavery is still a very active pursuit and a flourishing business in Central Africa). Generally these caravans were going in the direction opposite to ours, but we had to join them or perish in the waterless desert.
Sometimes we were hunted by gangs larger than our own; sometimes we were met at villages with volleys of rifle-fire (being taken, naturally, for what we pretended to be); sometimes we reached an oasis only to find it occupied by a patrol of French Senegalese troops--far more dangerous to us than the nomadic robbers for whom we were a match when not hopelessly outnumbered.
Whether we did what no Europeans have ever done before, I do not know, but we certainly went to places where Europeans had never been before, and "discovered" desert cities which were probably prehistoric ruins before a stone of Damascus was laid.
We encountered no Queens of Atlantis and found no white races of Greek origin, ruled by ladies of tempestuous petticoat, to whom it turned out we were distantly related.
Alas, no. We found only extremely poor, primitive, and dirty people, with whom we sojourned precisely as long as untoward circumstance compelled.
Of course, we could never have survived for a single month of those years, but for the desert-skill, the courage, resourcefulness, and experience of Hank and Buddy.
On the other hand, the ready wits of Digby, and our knowledge of Arabic, saved the situation, time after time, when we were in contact with our fellow-man.
On these occasions we became frightfully holy. Hank and Buddy were marabouts under a vow of silence, and we were Senussi on a mysterious errand, travelling from Kufra in the Libyan desert to Timbuktu, and visiting all sorts of holy places on the way.
Luckily for us, there were no genuine Senussi about; and the infinite variety of sects, with their different kinds of dervishes, and the even greater variety of people who spoke widely differing dialects of Arabic, made our task comparatively easy.
Probably our rifles, our poverty, and our obvious truculence did still more in that direction.
We suffered from fever, terrific heat, poisonous water, bad and insufficient food, and the hardships of what was one long campaign of active warfare to live.
At times we were very near the end, when our camels died, when a long journey ended at a dried-up well, when we were surrounded by a pack of the human wolves of the desert, and when we were fairly captured by a harka of Touaregs, suspicious of our bona fides. . . .
As I have said, an account of our katabasis would fill a volume, but the description of a few typical incidents will suffice to give an idea of it, without rendering the story as wearisome as was the journey.
For example, our discovery of the place where there certainly ought to have been "a strange fair people of a civilisation older, and in some ways higher, than our own; ruled over by a woman, so incredibly beautiful, so marvellously . . ." etc.
One day we rode over the crest of a long ridge of sand-covered rock--straight into a band of armed men who outnumbered us by ten to one, at least, and who were ready and waiting for us with levelled rifles.
We did as we had done before, on similar exciting occasions. The Holy Ones, Hank and Buddy, fell dumb, and Digby became the emissary of the Senussi Mahdi; I, his lieutenant.
Digby rode forward.
"Salamoune aleikoumi Esseleme, ekhwan" (Peace be unto you, brothers), said he, in solemn, sonorous greeting, to which a fine-looking old man replied, to my great relief, "Aselamu, alaikum, marhaba, marhaba" (Greetings to you and welcome), in a different-sounding Arabic from ours. It turned out later that the old gentleman took us for an advance-party of a big band of Touaregs who were near, and was only too charmed to find us so charming.
Digby then proceeded with the appropriate account of ourselves, alluding to the dumb forbidding Hank and Buddy, as most holy men, khouans, hadjis, marabouts, under a strict vow of silence that it would be ill work for any man to attempt to break. Himself and me he described as m'rabets, men hereditarily holy and prominent in faith and virtue.
How much of this our hearers understood, and how much of what they understood, they believed, I could not tell, but they were obviously relieved to find us friendly and not part of a larger force.
We were promptly invited to come along, and thought it best to comply, there being little reason against doing so and much against refusing. In any case they had "got us," from the moment we came upon their levelled rifles, our own slung behind us; and we were at their mercy. As we rode along, nominally guests, but feeling we were prisoners, I was interested to hear Digby assuring the old sheikh that though we were as holy as it is given to mere men to be, we were nevertheless good hefty proselytisers who carried the Q'ran in one hand and the sword in the other, fighting-men who would be pleased to chip in, if the Touaregs attacked his band.
The old gentleman returned thanks and said that, once home, they did not fear all the Touaregs in the Sahara, as the place was quite impregnable. This sounded attractive, and proved to be perfectly true.
What did trouble them, was the fact that when they set off with a caravan of camels for sale at Tanout, it was more than likely that they would, for months, have to fight a series of pitched battles or lose the whole of the wherewithal to purchase grain for their subsistence, for there was nothing a Touareg robber desired more than camels.
"It is the only wealth that carries itself," observed Digby sententiously.
After riding for some three or four hours towards some low rocky mountains, we reached them and approached a narrow and lofty pass. This we threaded in single file, and, coming to the top, saw before us an endless plain out of which arose a gara, an abrupt and isolated plateau, looking like a gigantic cheese placed in the middle of the level expanse of desert.
Toward this we rode for another hour or two, and discovered it to be a precipitous mountain, sheer, cliff-sided, with a flat top; the whole, I suppose, about a square mile in area.
Apparently it was quite inaccessible and untrodden by the foot of man, or even of mountain sheep or goat. Only an eagle, I imagined, had ever looked upon the top of that isolated square mile of rock.
I was wrong, however, the place proving to be a gigantic fort--a fort of the most perfect kind, but which owed nothing whatever to the hand of man.
Circling the cliff-like precipitous base of the mountain, we came to a crack in the thousand-foot wall, a crack that was invisible at a hundred yards.
Into this narrow fissure the sheikh led us in single file, and, squeezing our way between gigantic cactus, we rode along the upward-sloping bottom of a winding chasm that was not six feet wide.
Suddenly our path was cut by a deep ravine, some three yards wide, a great crack across the crack in which we were entombed. Bridging this was laid a number of trunks of the dôm palm, and over these a matting of palm-leaf and sand made a narrow but safe path for camels.
Obviously this bridge could easily be removed if necessary, and the place defended with the greatest ease, if any enemy were foolish enough to attempt to bridge the abyss while the defenders dropped boulders from terrific heights, and fired their rifles at point-blank range from behind the strong stone wall that faced the chasm.
Having crossed the bridge, we rode on upward to where this narrow slit in the mountain opened out into a big rock-enclosed square like a landing on a staircase--beyond which
