It is afternoon, but the sun's rays still pour down with great power upon rock and sand. How great the heat has been at midday may be seen by the quivering of the air as it rises from the ground and blurs all distant objects. It is seen, too, in the attitudes and appearance of a large body of soldiers encamped in a grove. Their arms are thrown aside, the greater portion of their clothing has been dispensed with. Some lie stretched on the ground in slumber, their faces protected from any chance rays which may find their way through the foliage above by little shelters composed of their clothing hung on two bows or javelins. Some, lately awakened, are sitting up or leaning against the trunks of the trees, but scarce one has energy to move.
