Of all the desert superstitions the one which appealed most to my imagination was the superstition of the desert drum. The Saharaman declares that far away from the abodes of men and desert cities, among the everlasting sand dunes, the sharp beating, or dull, distant rolling of a drum sometimes breaks upon the ears of travellers voyaging through the desolation. They look around, they stare across the flats, they see nothing. But the mysterious music continues. Then, if they be Sahara-bred, they commend themselves to Allah, for they know that some terrible disaster is at hand, that one of them at least is doomed to die. Often had I heard stories of the catastrophes which were immediately preceded by the beating of the desert drum. One night in the Sahara I was a witness to one which I have never been able to forget. On an evening of spring, accompanied by a young Arab and a negro, I rode slowly down a low hill of the Sahara, and saw in the sandy cup at my feet the tiny collection of hovels called Sidi-Massarli. I had been in the saddle since dawn, riding over desolate tracks in the heart of the desert. I was hungry, tired, and felt almost like a man hypnotised. The strong air, the clear sky, the everlasting flats devoid of vegetation, empty of humanity, the monotonous motion of my slowly cantering horse—all these things combined to dull my brain and to throw me into a peculiar condition akin to the condition of a man in a trance. At Sidi-Massarli I was to pass the night. I drew rein and looked down on it with lack-lustre eyes. I saw a small group of palm-trees, guarded by a low wall of baked brown earth, in which were embedded many white bones of dead camels. Bleached, grinning heads of camels hung from more than one of the trees, with strings of red pepper and round stones. Beyond the wall of this palm garden, at whose foot was a furrow full of stagnant brownish-yellow water, lay a handful of wretched earthen hovels, with flat roofs of palmwood and low wooden doors. To be exact, I think there were five of them. The Bordj, or Travellers’ House, at which I was to be accommodated for the night, stood alone near a tiny source at the edge of a large sand dune, and was a small, earth-coloured building with a pink tiled roof, minute arched windows, and an open stable for the horses and mules. All round the desert rose in humps of sand, melting into stony ground where the saltpetre lay like snow on a wintry world. There were but few signs of life in this place; some stockings drying on the wall of a ruined Arab café, some kids frisking by a heap of sacks, a few pigeons circling about a low square watchtower, a black donkey brooding on a dust heap. There were some signs of death; carcasses of camels stretched here and there in frantic and fantastic postures, some bleached and smooth, others red and horribly odorous.
