ere now upon the level terrace, and the storm
apparently spending its fury high up and behind them. But in spite of
the clearing of the air, he could not but notice that it was singularly
dark. What was more singular, the darkness seemed to have risen from
below, and to flow in upon them as they descended. A curtain of profound
obscurity, darker even than the mountain wall at their side, shut out
the horizon and the valley below. But for the temperature, Masterton
would have thought a thunderstorm was closing in upon them. An odd
feeling of uneasiness crept over him.

A few fitful gusts now came from the obscurity; one of them was
accompanied by what seemed a flight of small startled birds crossing the
road ahead of them. A second larger and more sustained flight showed his
astonished eyes that they were white, and each bird an enormous flake
of SNOW! For an instant the air was filled with these disks, shreds,
patches,--two or three clinging together,--like the downfall shaken from
a tree, striking the leather roof and sides with a dull thud, spattering
the road into which they descended with large rosettes that melted away
only to be followed by hundreds more that stuck and STAYED. In five
minutes the ground was white with it, the long road gleaming out ahead
in the darkness; the roof and sides of the wagon were overlaid with it
as with a coating of plaster of Paris; the harness of the horses,
and even the reins, stood out over their steaming backs like white
trappings. In five minutes more the steaming backs themselves were
blanketed with it; the arms and legs of the outside passengers pinioned
to the seats with it, and the arms of the driver kept free only by
incessant motion. It was no longer snowing; it was "snowballing;" it
was an avalanche out of the slopes of the sky. The exhausted horses
floundered in it; the clogging wheels dragged in it; the vehicle at last
plunged into a billow of it--and stopped.

The bewildered and half blinded passengers hurried out into the road
to assist the driver to unship the wheels and fit the steel runners
in their axles. But it was too late! By the time the heavy wagon was
converted into a sledge, it was deeply imbedded in wet and clinging
snow. The narrow, long-handled shovels borrowed from the prospectors'
kits were powerless before this heavy, half liquid impediment. At last
the driver, with an oath, relinquished the attempt, and, unhitching his
horses, collected the passenger
