The side of the cut was steep, and the soft sand and clay did not make a secure footing. But when the black received the signal from Trevison he did not hesitate. Crouching like a great cat at the edge, he slid his forelegs over until his hoofs sank deep into the side of the cut. Then with a gentle lurch he drew his hind legs after him, and an instant later was gingerly descending, his rider leaning far back in the saddle, the reins held loosely in his hands.
It looked simple enough, the way the black was doing it, and Trevison's demeanor indicated perfect trust in the animal and in his own skill as a rider. But the laborers ceased working and watched, grouped, gesturing; the staccato coughing of the steam shovel died gaspingly, as the engineer shut off the engine and stood, rooted, his mouth agape; the fireman in the dinky engine held tightly to the cab window. Murphy muttered in astonishment, and Carson chuckled admiringly, for the descent was a full hundred feet, and there were few men in the railroad gang that would have dared to risk the wall on foot.
The black had gained impetus with distance. A third of the slope had been covered when he struck some loose earth that shifted with his weight and carried his hind quarters to one side and off balance. Instantly the rider swung his body toward the wall of the cut, twisted in the saddle and swung the black squarely around, the animal scrambling like a cat. The black stood, braced, facing the crest of the cut, while the dislodged earth, preceded by pebbles and small boulders, clattered down behind him. Then, under the urge of Trevison's gentle hand and voice, the black wheeled again and faced the descent.
"I wouldn't ride a horse down there for the damned railroad!" declared Murphy.
"Thrue for ye--ye c'udn't," grinned Carson.
"A man could ride anywhere with a horse like that!" remarked the fireman, fascinated.
"Ye'd have brought a cropper in that slide, an' the road wud be minus a coal-heaver!" said Carson. "Wud ye luk at him now!"
The black was coming down, forelegs asprawl, his hind quarters sliding in the sand. Twice as his fore-hoofs struck some slight obstruction his hind quarters lifted and he stood, balanced, on his forelegs, and each time Trevison averted the impending catastrophe by throwing himself far back in the saddle and slapping the black's hips sharply.
