Hare thought there must be an end to it some time, yet it seemed as though he were never to cross that black forbidding inferno.  Blistered by the heat, pierced by the thorns, lame from long toil on the lava, he was sorely spent when once more he stepped out upon the bare desert.  On pitching camp he made the grievous discovery that the water-bag had leaked or the water had evaporated, for there was only enough left for one more day.  He ministered to thirsty dog and horse in silence, his mind revolving the grim fact of his situation.

His little fire of greasewood threw a wan circle into the surrounding blackness.  Not a sound hinted of life.  He longed for even the bark of a coyote.  Silvermane stooped motionless with tired head.  Wolf stretched limply on the sand.  Hare rolled into his blanket and stretched out with slow aching relief.

He dreamed he was a boy roaming over the green hills of the old farm, wading through dewy clover-fields, and fishing in the Connecticut River.  It was the long vacationtime, an endless freedom.  Then he was at the swimming-hole, and playmates tied his clothes in knots, and with shouts of glee ran up the bank leaving him there to shiver.

When he awakened the blazing globe of the sun had arisen over the eastern horizon, and the red of the desert swathed all the reach of valley.

Hare pondered whether he should use his water at once or dole it out.  That ball of fire in the sky, a glazed circle, like iron at white heat, decided for him.  The sun would be hot and would evaporate such water as leakage did not claim, and so he shared alike with Wolf, and gave the rest to Silvermane.

For an hour the mocking lilac mountains hung in the air and then paled in the intense light.  The day was soundless and windless, and the heat-waves rose from the desert like smoke.  For Hare the realities were the baked clay flats, where Silvermane broke through at every step; the beds of alkali, which sent aloft clouds of powdered dust; the deep gullies full of round bowlders; thickets of mesquite and prickly thorn which tore at his legs; the weary detour to head the canyons; the climb to get between two bridging mesas; and always the haunting presence of the sad-eyed dog.  His unrealities were the shimmering sheets of water in every low place; the baseless mountains floating in the air; the green slopes rising close at hand; beautiful buttes of dark blue riding the open sand, like monstrous barks at sea; the changing outlines of desert shapes in pink haze and veils of purple and white lustre—­all illusions, all mysterious tricks of the mirage.

In the heat of midday Hare yielded to its influence and reined in his horse under a slate-bank where there was shade.  His face was swollen and peeling, and his lips had begun to dry and crack and taste of alkali.  Then Wolf pattered on; Silvermane kept at his heels; Hare dozed in the saddle.  His eyes burned in their sockets from the glare, and it was a relief to shut out the barren reaches.  So the afternoon waned.
