ejection of molten lava to a great
height from active volcanoes; these had become globular in falling, and,
having cooled before they reached the earth, they retained their forms
as hard spherical bodies, precisely resembling cannon shot. The exterior
was brown, and appeared to be rich in iron. The smaller specimens
were the more perfect spheres, as they cooled quickly; but many of
the heavier masses had evidently reached the earth when only half
solidified, and had collapsed upon falling. The sandy plain was covered
with such vestiges of volcanic action, and the infernal bombs lay as
imperishable relics of a hailstorm such as may have destroyed Sodom and
Gomorrah.

Passing through this wretched solitude, we entered upon a scene of
surpassing desolation. Far as the eye could reach were waves like a
stormy sea, gray, coldlooking waves in the burning heat; but no drop of
water. It appeared as though a sudden curse had turned a raging sea to
stone. The simoom blew over this horrible wilderness, and drifted the
hot sand into the crevices of the rocks, and the camels drooped their
heads before the suffocating wind; but still the caravan noiselessly
crept along over the rocky undulations, until the stormy sea was passed;
once more we were upon a boundless plain of sand and pebbles.

In forty-six hours and forty-five minutes' actual marching from Korosko,
we reached Moorahd, "the bitter well." This is a mournful spot, well
known to the tired and thirsty camel, the hope of reaching which has
urged him fainting on his weary way to drink one draught before he dies.
This is the camel's grave. Situated half way between Korosko and Abou
Hammed, the well of Moorahd is in an extinct crater, surrounded upon all
sides but one by precipitous cliffs about three hundred feet high. The
bottom is a dead flat, and forms a valley of sand about two hundred and
fifty yards wide. In this bosom of a crater, salt and bitter water is
found at a depth of only six feet from the surface. To this our tired
camels frantically rushed upon being unloaded.

The valley was a "valley of dry bones." Innumerable skeletons of camels
lay in all directions-the ships of the desert thus stranded on their
voyage. Withered heaps of parched skin and bone lay here and there, in
the distinct forms in which the camels had gasped their last. The dry
desert air had converted the hide into a coffin. There were no flies
here, thus there were no worms to devour the carcasse
