Beyond we had an easy descent into Wadi Murrmiya, whose middle bristled with lava like galvanised iron, on each side of which there were smooth sandy beds, good going. After a while we came to a fault in the flow, which served as a track to the other side. By it we crossed over, finding the lava pocketed with soils apparently of extreme richness, for in them were leafy trees and lawns of real grass, starred with flowers, the best grazing of all our ride, looking the more wonderfully green because of the blue-black twisted crusts of rock about. The lava had changed its character. Here were no piles of loose stones, as big as a skull or a man’s hand, rubbed and rounded together; but bunched and crystallised fronds of metallic rock, altogether impassable for bare feet.
