But on the siding stood a couple of flats, empty; and with his hair straight on centres, the little wiper ran for them and mounted the nearest. The steel train was jumping. Aloysius, bunching his muscle, ran the length of the two flats for a head, and, from the far corner, threw himself across the gap, like a bat, on a load of the runaway steel. Scrambling to his feet, he motioned and yelled to the hoboes, who were pouring frantic out on the hind flat of the string, to set brakes; then he made ahead for the engine. It was a race with the odds all wrong, for with every yard Aloysius gained, the train gained a dozen. By the time he reached the tender, breathless, and slid down the coal into the deserted cab, the train was heading into Little Horn gap, and every Italian aboard, yelling for life. Aloysius jumped into the levers, poked his head through the window, and looked at the drivers. They were in the back motion, and in front of them the sand was streaming wide open. The first thing he did was to shut half it off--the fight could not be won by wasting ammunition. Over and over again he jerked at the air. It was refusing its work. Where so many a hunted runner has turned for salvation there was none for Aloysius. He opened and closed, threw on and threw off; it was all one, and all useless. The situation was as simple as it was frightful. Even if they didn't leave the track, they were certain to smash into Number Sixteen, the up-passenger, which must meet them somewhere on the hill. Aloysius's fingers closed slowly on the sand lever. There was nothing on earth for it but sand, merely sand; and even the wiper's was oozing with the stream that poured from the tank on the whiskered rails. He shut off a bit more, thinking of the terrific curves below, and mentally calculated--or tried to--how long his steam would last to reverse the drivers--how he could shovel coal and sand the curves at the same time--and how much slewing the Italians at the tail of the kite could stand without landing on the rocks. The pace was giddy and worse. When his brain was whirling fastest, a man put a hand on his shoulder. Aloysius started as if Davy Jones had tapped him, and between bounces looked, scared, around. He looked into a face he didn't know from Adam's, but there was sand in the eyes that met his. "What can I do?" Aloysius saw the man's lips move, and, without taking his hands from the levers, bent his head to catch the words. "What can I do?" shouted the man at his elbow. "Give me steam--steam," cried the wiper, looking straight ahead. It was the foreman of the steel gang from the caboose. Aloysius, through the backs of his eyes, saw him grab the shovel and make a pass at the tender. Doing so, he nearly took a header through the gangway, but he hung to the shovel and braced himself better.
