Slowly flapped the leaden wings of Time on that dismal day. Each weary hour brought a grievous accession, but no alleviation, to the fearful torments endured. The stagnation of the atmosphere continued undiminished; the pangs of thirst increased, but no water arrived; and the sun's despotic dominion on the meridian, appeared to know no termination. At four o'clock, when the heat was nothing abated, distressing intelligence was received that one of the seamen, who during the preceding night had accompanied the captain of the schooner-of-war from Goobut el Kharab, and had unfortunately lost his way, could nowhere be found--the gunner, with six men, having long painfully searched the country side for their lost messmate, but to no purpose; Abroo, the son of whom old Aboo Bekr was justly proud, and who was indeed the flower of his tribe, immediately volunteered to go in quest of the missing sailor, and he subsequently returned with the cheering intelligence that his efforts had been crowned with success. Overwhelmed by heat and thirst, the poor fellow, unable to drag his exhausted limbs further, had crept for shelter into a fissure of the heated lava, where he had soon sunk into a state of insensibility. Water, and the use of a lancet, with which the young midshipman who heroically accompanied the exploring party had been provided, restored suspended animation sufficiently to admit of his patient being conveyed on board the "Constance" alive; but, alas! he never reached Tajura; neither did one of the brave tars who sought their lost comrade under the fierce rays of the sun, nor indeed did any of the adventurous expedition, escape without feeling, in after severe illness, the unwholesome influence upon the human constitution of that waste and howling wilderness.
