TWO switch lights twinkled; one at the east, and one at the west end of the siding. For the rest all was blackness. Half way between the switch lights, snuggled close against the single-tracked main line, the station, little more than a shanty and too insignificant to boast a night operator, loomed up shadowy and indistinct. Away to the westward, like jagged points sticking up into the night and standing out in relief against the skyline, the Rockies reared their peaks. And the spell of the brooding mountains seemed to lie over all the desolate, butte-broken surrounding country-for all was utter silence. And then there came a sound, low at first, like a strange muttering from somewhere to the westward. It died away, grew louder, was hushed again-and broke into a sustained roar. Came then the quick, short gasps of the exhaust-it was a freight, and a heavy one. And suddenly, from up the track, circling an intervening butte, an electric headlight cut streaming through the black. It touched the little station in a queerly inquisitive way in the sweep of its arc, lingered an instant over the platform, then swung to the right of way, and held there, the metals glistening like polished silver ribbons under the flood of light.
