“ Then the sand is dotted with clumps of the zumaran, and other thick-leaved plants, whose roots, stretching along the surface, draw sufficient moisture for their existence from the air; round these may be marked the tiny footprints left by the nightly gambols of the gerboa. A clump of palm-trees, or a few mimosas, are at last seen on the horizon, and welcomed with joy by the thirsty caravan; the camels now increase their pace, the Arab’s step becomes more elastic, though it will be hours before the wished-for spring is reached. ”
