“Steady, my boy--no you don't!” This as Diablo stuck his neck straight out like an arrow and sought to hold the bit tight against the bridle teeth, that he might race at his own sweet will. Back came the right hand, then the left, three vicious saws, and the bit was loose and Diablo's head drawn down again close to the martingale. Lucretia and Lauzanne were pulling to the front.
“Go on!” called Porter to Ned Carter; “I want to see the little mare in her stride. Take them out at three-quarter gallop down the back stretch. I'll be treading your heels off.”
By this they were opposite the old stand, where Shandy was hiding. The boy, surmising that a gallop was on, and anxious to see them as they rounded the turn going down the back, had knocked a board loose to widen the crack. As the horses came abreast, Shandy, leaning forward in his eagerness, dislodged it at the top, and it fell with a clatter, carrying him half through the opening. The wind was blowing fair across the little stand, so the scent of the boy came to Diablo's nostrils at the same instant the startling noise reached his nervous ears. In a swerve he almost stopped, every muscle of his big body trembling in affright. Porter was nearly thrown from his seat by this crouching side step; the horse seemed to shrink from under him. Just for an instant, but the reins had flapped loose against the wet neck and Diablo felt freedom. With a snort he plunged forward like a wounded buck, and raced madly after Lucretia, who had bolted when the crash came.
Porter had lost a stirrup in the sudden twist, and the reins had slipped through his fingers as he grabbed the mane on Diablo's wither to pull his weight back into the saddle.
Now the black neck was straight and taut, flatcapped by the slim ears that lay close to the throatlatch. The thunder of his pounding hoofs reached to the ears of Lucretia and Lauzanne in front, and urged them onward. Carter had sat down in the saddle, and taken a steadying pull at the brown mare. Even Lauzanne seemed lifted out of his usual lethargy, and, widemouthed, was pulling Allis out of the saddle.
“Curse the brute!” gasped Porter, burying his knees in the saddle flaps, and searching for the dangling stirrup with the toe of his right foot. Once he almost had it, but missed; the iron, swinging viciously, caught Diablo in the flank--it made little difference, his terror was complete. All the time Porter was kneading the dangling reins back through forefinger and thumb, shortening his hold for a strong pull at the galloping brute's head.
