There a scene met his eye as unexpected as it was appalling. The entire surface of the Mediterranean was aglow with phosphorescence, and the sun was veiled completely by a heavy cloud that seemed to cover the whole expanse of the sky. This cloud was not black, but of a bloody hue, and the atmosphere was so densely charged with sulphur that it was almost impossible to breathe. The sea was boiling more furiously than ever, and the puffs of vapor that had before only occasionally filtered through the waves now leaped up incessantly, each puff attended with a slight explosion; the vapor was grayish when it first arose from the water, but as it ascended it became red, mingling at length with the bloody cloud that each moment acquired greater density. The wind blew fitfully, sometimes amounting to a gale and then utterly vanishing without the slightest warning. Soon the bloody cloud seemed to settle of its own weight upon the sea, growing so thick that the eye could not penetrate it, and a few feet from the yacht all was inky darkness. Monte-Cristo hurried to the captain, who was endeavoring to quiet the superstitious fears of the sailors. Drawing him aside, he said, in a low tone: "Giacomo, we are in frightful danger. This elemental disturbance is volcanic, and how it will end cannot be foretold. No doubt an earthquake is devastating the nearest land, or will do so before many hours have elapsed. At any moment rocks or islands may arise from the sea, and obstruct our passage. All we can do is to hold ourselves in readiness for whatever calamity may happen, and make for Crete as rapidly as possible, with the hope of eventually getting beyond the volcanic zone. Do not enlighten the crew as to the cause of the disturbance; did they know, or even suspect it, they could not be controlled, but would become either stupefied or reckless. Try to convince them that we are simply in the midst of a severe electrical storm that will speedily exhaust its fury and subside. Now, to work, and remember that everything depends upon your courage and resolution." Giacomo rejoined the sailors, who were huddled together at the stern of the yacht like so many frightened sheep. He spoke to them, doing his utmost to reassure them, and ultimately succeeded so well that they resumed their neglected duties with some show of alacrity and even cheerfulness. Meanwhile, Monte-Cristo, with folded arms and an outward show of calmness, was pacing the deck as if nothing unusual were in progress, and his demeanor was not without its effect on the sailors, who looked upon him with a species of awe and admiration. At times he went below to cheer the drooping spirits of his beloved Haydee, but speedily returned that the influence of his presence might not be lost.
