descends on one with an intolerable oppression.

The road traverses no villages, and not even a ring of nomad tents is
visible in the distance on the wide stretches of arable land. At
infrequent intervals our motor passed a train of laden mules, or a group
of peasants about a well, and sometimes, far off, a fortified farm
profiled its thick-set angle-towers against the sky, or a white _koubba_
floated like a mirage above the brush, but these rare signs of life
intensified the solitude of the long miles between.

At midday we were refreshed by the sight of the little oasis around the
military-post of Settat. We lunched there with the commanding officer,
in a cool Arab house about a flowery patio, but that brief interval
over, the fiery plain began again. After Settat the road runs on for
miles across the waste to the gorge of the Oued Ouem, and beyond the
river it climbs to another plain so desperate in its calcined aridity
that the prickly scrub of the wilderness we had left seemed like the
vegetation of an oasis. For fifty kilometres the earth under our wheels
was made up of a kind of glistening red slag covered with pebbles and
stones. Not the scantest and toughest of rock-growths thrust a leaf

the wicked glister of their purple flanks seemed like a volcanic
upheaval of the plain. For some time we had watched the clouds gathering
over them, and as we got to the top of the defile rain was falling from
