Meantime Claude, who had lost all consciousness of an audience in his joy at being again upon the back of a fine animal, was increasing the pace of his steed. The long, light steps multiplied in number, the black hoofs flew faster yet, till the on-lookers marvelled at the ease of the tremendous speed, and Will Paca shook his head as he thought of his Doris and her rider.

"I'll give you three lengths start on the track, Will," cried Trevor, as de Mailly flew by for the fourth time, never moving a hair's-breadth in the saddle.

"Egad, he'll need it!" put in Sir Charles.

Deborah, her cheeks slightly flushed, moved to one side where she could watch without interruption. She saw Claude pass the stable and reach the far corner of the paddock. There something happened. A thing which looked, at the distance, like a black thread, shot suddenly up from the ground and struck at Castor's leg as he passed. The horse gave a quick, terrified plunge, which made de Mailly reel in the saddle, and then the animal, maddened with fear, started forward like a whirlwind. He had reared completely about and was running frantically towards the open gateway. At the beginning there had been a slight scream from Lucy, and now the men, their faces very pale, pulled the women quickly away from the opening. Deborah moved of her own accord, her eyes fixed fast on the horse, for she had seen what started its flight. In an instant horse and rider had flashed, comet-like, out at the gate, and, as they passed, Deborah knew that de Mailly had looked at her, and she had seen something very like a smile cross his set lips. Beyond the gate the horse veered again and made towards the south, in the direction of the tobacco-fields.

"HORSE AND RIDER HAD FLASHED OUT AT THE GATE"

Claude saw, with relief, that he had an apparently unobstructed space before him. It was all that he could do now to keep himself on the horse, who no longer went at an even gait, but varied his gallop with leaps and plunges caused by pain. He was utterly beyond all control. Claude lay over on his back, both hands twisted in the long mane, his eyes half closed, breathing with some difficulty, but quite sure of himself so long as his way was clear. Suddenly, however, as he caught a glimpse of the fields beyond, his heart rose into his throat, and then sank again with a sensation which made him dizzy. A hundred yards ahead was a twenty-foot ditch of water, which no living horse could clear. If Castor saw it, and had still sense of his own, he might turn off. If not, the horse was lost, and Claude himself must take desperate chances. Many things flashed through his mind in the ensuing seconds. Most vividly of all the figure of Deborah, as he had seen her a moment before, stood out before him. Then for one more instant his mind was a white blank. They were ten yards from the stream now, and the horse was moving straight on. Mechanically, Claude took his left foot from the stirrup and swung it over Castor's back. For one frightful instant he lay full along the animal. Then, not very much aware of what he was doing, he had let himself over the side, felt solid ground whirl under his feet, and knew that all was well with him. A moment later he vaguely heard the heavy splash and the human-like scream that told of the good animal's death. Not very long after that he was looking into Vincent's face, and, as a brandy flask was held out to him, he murmured, with as much feeling as he was capable of just then:

"Monsieur, I shall never be able to express to you my regret. I have not an idea how it occurred. Believe me—"

But Vincent was actually laughing as he replied: "My dear sir, when a poisonous snake sends its fangs into your horse's leg, its rider need offer no excuse for being run away with. And, 'pon my soul, for the sake of learning how to ride as you have done, I'd sacrifice every beast that ever was stalled on this place.—Eh, Charlie?"
