The shadows were creeping up the mountain side. Overhead the wide sweep
of sky began to glitter with white stars. A little chill breeze sprang
up in the west and fanned the fire, sending a fairy shower of tiny
lemon-yellow sparks into the air. And borne on the breeze came a hoarse
pounding and drumming that grew momentarily louder and reverberated from
wall to wall. The ground trembled and the grazing burros lifted their
shaggy heads inquiringly.

"She's almost up," said Wade. Craig nodded and replaced his pipe between
his teeth. The noise became multisonous. With the clangor of the
pounding wheels came the stertorous gasping of the engines, the creak
and clatter of protesting metal. The uproar filled the pass deafeningly.

"She's making hard work of it," shouted Craig.

"Probably a heavy train," Wade answered.

Then a path of pale light swept around the elbow of the mountain and the
wheezing, puffing monsters reached the head of the grade. The watchers
could almost hear the sighs of relief from the two big mountain-climbers
as they found the level track beneath them. Their breathing grew easier,
quieter as they clanged slowly across the pass a few rods below the
camp. The burros, having satisfied their curiosity, went back to supper.
The firemen in the cab windows raised their hands in greeting and the
campers waved back. Behind the engines came a baggage and express car,
then a day coach, a diner and a sleeper. Slower and slower moved the
train and finally, with a rasping of brakes and the hissing of released
steam, it stopped.

"What's up?" asked Wade.
