While the Arabs were preparing breakfast, Edgar searched for a spot where the sheik could lie in shelter during the mid-day heat; for, hot as it was on the desert sands, the heat was fully as great on the bare rocks of the hills. After some search he found a spot where two ledges of rock ran parallel to each other, with a passage of some six feet between them, on each side of which they rose perpendicularly some twelve feet in height. The fissures ran nearly north and south, and therefore, except for an hour at noon, the bottom was entirely in shade.
