Like automatons the silent laborers started the car.
“Drill, ye terriers, drill! Drill, ye terriers, drill!” sang Casey, as he stood at the wheel-brake.
The car gathered momentum. McDermott was the last to let go.
“Good luck to yez!” he shouted, hoarsely.
“Mac, tell thim yez saw me!” called Casey. Then he waved his hand in good-by to the crowd. Their response was a short, ringing yell. They watched the car glide slowly out of sight.
For a few moments Casey was more concerned with the fact that a breeze had blown out his pipe than with anything else. Skilful as years had made him, he found unusual difficulty in relighting it, and he would not have been beyond stopping the car to accomplish that imperative need. When he had succeeded and glanced back the station was out of sight.
Casey fixed his eyes upon the curve of the track ahead where it disappeared between the sage-covered sandy banks. Here the grade was scarcely perceptible to any but experienced eyes. And the gravel-car crept along as if it would stop any moment. But Casey knew that it was not likely to stop, and if it did he could start it again. A heavy-laden car like this, once started, would run a long way on a very little grade. What worried him was the creaking and rattle of wheels, sounds that from where he stood were apparently very loud.
He turned the curve into a stretch of straight track where there came a perceptible increase in the strength of the breeze against his face. While creeping along at this point he scooped out a hole in the gravel mound on the car, making a place that might afford some protection from Indian bullets and arrows. That accomplished, he had nothing to do but hold on to the wheel-brake, and gaze ahead.
It seemed a long time before the speed increased sufficiently to insure him against any danger of a stop. The wind began to blow his hair and whip away the smoke of his pipe. And the car began to cover distance. Several miles from the station he entered the shallow mouth of a gully where the grade increased. His speed accelerated correspondingly until he was rolling along faster than a man could run. The track had been built on the right bank of the gully which curved between low bare hills, and which grew deeper and of a rougher character. Casey had spiked many of the rails over which he passed.
He found it necessary to apply the brake so that he would not take the sharp curves at dangerous speed. The brake did not work well and gave indications that it would not stand a great deal. With steady, rattling creak, and an occasional clank, the car rolled on.
