four feet;
they stood just about seven feet apart, all over the vast desert; each of
them was a mere snow-mound, now; in any direction that you proceeded (the
same as in a well laid out orchard) you would find yourself moving down a
distinctly defined avenue, with a row of these snow-mounds an either side
of it--an avenue the customary width of a road, nice and level in its
breadth, and rising at the sides in the most natural way, by reason of
the mounds. But we had not thought of this. Then imagine the chilly
thrill that shot through us when it finally occurred to us, far in the
night, that since the last faint trace of the wheel-tracks had long ago
been buried from sight, we might now be wandering down a mere sage-brush
avenue, miles away from the road and diverging further and further away
from it all the time. Having a cake of ice slipped down one's back is
placid comfort compared to it. There was a sudden leap and stir of blood
that had been asleep for an hour, and as sudden a rousing of all the
drowsing activities in our minds and bodies. We were alive and awake at
once--and shaking and quaking with consternation, too. There was an
instant halting and dismounting, a bending low and an anxious scanning of
the road-bed. Useless, of course; for if a faint depression could not be
discerned from an altitude of four or five feet above it, it certainly
could not with one's nose nearly against it.

CHAPTER XXXII.

We seemed to be in a road, but that was no proof. We tested this by
walking off in various directions--the regular snow-mounds and the
regular avenues between them convinced each man that he had found the
true road, and that the others had found only false ones. Plainly the
situation was desperate. We were cold and stiff and the horses were
tired. We decided to build a sage-brush fire and camp out till morning.
This was wise, because if we were wandering from the right road and the
snow-storm continued another day our case would be the next thing to
hopeless if we kept on.

All agreed that a camp fire was what would come nearest to saving us,
now, and so we set about building it. We could find no matches, and so
we tried to make shift with the pistols. Not a man in the party had ever
tried to do such a thing before, but not a man in the party doubted that
it could be done, and without any trouble--because every man in the party
had read about it in books many a time and had naturally come t
