more gaining hard ground. But he discovered that it was useless to try
to judge distance on the desert. What had appeared miles at his last
look turned out to be only rods.

It was good to get into the saddle again and face clear air. Far away
the black spur again loomed up, now surrounded by groups of mesas with
sage-slopes tinged with green. That surely meant the end of this long
trail; the faint spots of green lent suggestion of a desert waterhole;
there Mescal must be, hidden in some shady canyon. Hare built his hopes
anew.

So he pressed on down a plain of bare rock dotted by huge bowlders; and
out upon a level floor of scant sage and greasewood where a few living
creatures, a desert-hawk sailing low, lizards darting into holes, and a
swiftly running ground-bird, emphasized the lack of life in the waste.
He entered a zone of clay-dunes of violet and heliotrope hues; and then a
belt of lava and cactus. Reddish points studded the desert, and here and
there were meagre patches of white grass. Far away myriads of cactus
plants showed like a troop of distorted horsemen. As he went on the
grass failed, and streams of jagged lava flowed downward. Beds of
cinders told of the fury of a volcanic fire. Soon Hare had to dismount
to make moccasins for Wolf's hind feet; and to lead Silvermane carefully
over the cracked lava. For a while there were strips of ground bare of
lava and harboring only an occasional bunch of cactus, but soon every
foot free of the reddish iron bore a projecting mass of fierce spikes and
thorns. The huge barrel-shaped cacti, and thickets of slender dark-green
rods with bayonet points, and broad leaves with yellow spines, drove Hare
and his sore-footed fellow-travellers to the lava.

Hare thought there must be an end to it some time, yet it seemed as
