This sufficiently showed the presence of hidden enemies. "Our situation," says Bruce, "was one of the most desperate that could be figured. We were in the middle of the most barren, inhospitable desert in the world, and it was with the utmost difficulty that, from day to day, we could carry wherewithal to assuage our thirst. We had with us the only bread it was possible to procure for some hundred miles; lances and swords were not necessary to destroy us; the bursting or tearing of a girba, the lameness or death of a camel, a thorn or sprain in the foot, which might disable us from walking, were as certain death to us as a shot from a cannon. There was no staying for one another; to lose time was to die, because, with the utmost exertion our camels could make, we scarce could carry along with us a scanty provision of bread and water sufficient to keep us alive." That desert, which did not afford inhabitants for the assistance or relief of travellers, contained, nevertheless, more than sufficient for destroying them; for large tribes of Arabs (two or three thousand encamped together) were cantoned wherever there was water enough to supply their numerous herds of cattle, and Bruce fully expected that in the morning he should be attacked by these merciless robbers. He therefore briefly addressed his people, who uttered a loud cry, "God is great! let them come!" but, when the day broke, no Arabs appeared; all was still: Bruce, however, took Ismael and two Barbarins along with him, to see who these neighbours could be. They soon traced in the sand the footsteps of the man who had been at their camels; and, following them behind the point of a rock which seemed calculated for concealing thieves, they saw two ragged, old, dirty tents, pitched with grass cords.
