We entered a dead level plain of orange-colored sand, surrounded by pyramidical hills. The surface was strewn with objects resembling cannon shot and grape of all sizes from a 32-pounder downward, and looked like the old battle-field of some infernal region–rocks glowing with heat, not a vestige of vegetation, barren, withering desolation. The slow rocking step of the camels was most irksome, and, despite the heat, I dismounted to examine the Satanic bombs and cannon shot. Many of them were as perfectly round as though cast in a mould, others were egg-shaped, and all were hollow. With some difficulty I broke them, and found them to contain a bright red sand. They were, in fact, volcanic bombs that had been formed by the 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
