Immediately opposite to Oomergooloof is a projecting spur from Jebel Oobnoo, a lofty range visible to the westward; and this divides the plain into two valleys, whereof the southern-most is denominated Wady Arfa. The Marie range here towers overhead, steep and precipitous, to the height of about nine hundred feet; stupendous masses of rock which have been detached from the summit, and strew the entire base, corroborating the assertion of the Danakil that earthquakes are frequently felt in the vicinity. Nomade tribes with their families and flocks, having settled at the wells which exist at a distance, had compelled the gentler portion of the Libyan creation to resort to regions more blest with water; and not even a desert-loving gazelle was espied during the march of twelve miles. Ibrahim Shehem Abli had long viewed with the eye of bigoted disapproval, the attentions paid by one of the Mohammadan followers to two canine companions of the party, pets that had survived the passage of the fiery Tehama, but whose feet had become so lacerated by the hot lava boulders as to incapacitate them from walking. Quilp--for so the offending Moslem was styled from his striking resemblance to that notable character--was in the act of extricating his wire-haired charge from the panniers wherein they travelled, when the irascible little warrior approached, and, drawing his trenchant blade, swore with a dreadful anathema to exterminate him on the spot. "Dog, and father of dogs," he exclaimed, seizing the dismayed mortal by the throat, "beware how thou again defilest thy fingers with those accursed curs, or by the beard of the Prophet I will sever thy gullet as one who has brought foul discredit upon the faith." Then relaxing his grasp, and sheathing his creese with a horizontal flourish, he threw himself into the attitude of a slaughtered victim, and closed the significant lecture by mimicry of the gurgle heard in a divided windpipe, whence the tide of life is welling.
