The southern parts of Libya are all deep sand and parched soil, a desert of wide extent that produces nothing, one vast plain destitute of grass, herb, vegetation, and water; or if a remnant of the scanty rain stands here and there in a hollow. place, it is turbid and evil-smelling, undrinkable even in the extremity of thirst. The land is consequently uninhabited; savage, dried up, barren, droughty, how should it support life? The mere temperature, an atmosphere that is rather fire than air, and a haze of burning sand, make the district quite inaccessible.
