In this unventilated and diabolical hollow, dreadful indeed were the sufferings in store both for man and beast. Not a drop of fresh water existed within many miles; and, notwithstanding that every human precaution had been taken to secure a supply, by means of skins carried upon camels, the very great extent of most impracticable country to be traversed, which had unavoidably led to the detention of nearly all, added to the difficulty of restraining a multitude maddened by the tortures of burning thirst, rendered the provision quite insufficient; and during the whole of this appalling day, with the mercury in the thermometer standing at 126 degrees under the shade of cloaks and umbrellas--in a suffocating Pandemonium, depressed five hundred and seventy feet below the ocean, where no zephyr fanned the fevered skin, and where the glare arising from the sea of white salt was most painful to the eyes; where the furnace-like vapour exhaled, almost choking respiration, created an indomitable thirst, and not the smallest shade or shelter existed, save such as was afforded, in cruel mockery, by the stunted boughs of the solitary leafless acacia, or, worse still, by black blocks of heated lava, it was only practicable, during twelve tedious hours, to supply to each of the party two quarts of the most mephitic brick-dust-coloured fluid, which the direst necessity could alone have forced down the parched throat, and which, after all, far from alleviating thirst, served materially to augment its insupportable horrors.
