The schooner, although riding safely at anchor near the western extremity, was altogether concealed by precipitous walls that towered above her raking masts, and kept the party in uncertainty of her arrival. Crossing the lone valley of Marmoriso, a remnant of volcanic action, rent and seamed with gaping fissures, the road turned over a large basaltic cone, which had brought fearful devastation upon the whole surrounding country, and here one solitary gazelle browsed on stubble-like vegetation scorched to a uniform brown. Skirting the base of a barren range, covered with heaps of lava blocks, and its foot ornamented with many artificial piles, marking deeds of blood, the lofty conical peak of Jebel Seearo rose presently to sight, and not long afterwards the far-famed Lake Assal, surrounded by dancing mirage, was seen sparkling at its base. The first glimpse of the strange phenomenon, although curious, was far from pleasing. An elliptical basin, seven miles in its transverse axis, half filled with smooth water of the deepest caerulean blue, and half with a solid sheet of glittering snow-white salt, the offspring of evaporation--girded on three sides by huge hot-looking mountains, which dip their bases into the very bowl, and on the fourth by crude half-formed rocks of lava, broken and divided by the most unintelligible chasms,--it presented the appearance of a spoiled, or at least of a very unfinished piece of work. Bereft alike of vegetation and of animal life, the appearance of the wilderness of land and stagnant water, over which a gloomy silence prevailed, and which seemed a temple for ages consecrated to drought, desolation, and sterility, is calculated to depress the spirit of every beholder. No sound broke on the ear; not a ripple played upon the water; the molten surface of the lake, like burnished steel, lay unruffled by a breeze; the fierce sky was without a cloud, and the angry sun, like a ball of metal at a white heat, rode triumphant in a full blaze of noontide refulgence, which in sickening glare was darted back on the straining vision of the fainting wayfarer, by the hot sulphury mountains that encircled the still, hollow, basin. A white foam on the shelving shore of the dense water, did contrive for a brief moment to deceive the eye with an appearance of motion and fluidity; but the spot, on more attentive observation, ever remained unchanged--a crystallised efflorescence.
