Henri's shot was equally fortunate. Apparently it hit one of the Indians in the thigh, for he dropped and lay still. The horse instantly stopped, its fore legs thrust straight in front of it. Although untouched it remained by its master.

This totally unexpected welcome was more than the cowardly Indians could stand. With wild shrieks they rode off at full gallop, leaving two of their number and three steeds on the scene of action.

"We will take that horse!" exclaimed Henri, pointing to the one that remained by the body of its rider.

So saying he advanced cautiously so as not to affright the animal. Dacres, having recharged the empty chambers of his revolver, watched the proceedings. He did not feel at all capable of tackling a partly savage animal.

The Indian to whom it belonged still lay on the grass, his body huddled up and the long hide rope that served as a bridle and tether combined grasped in his hand.

"Look out!" shouted Dacres.

The warning came a trifle too late. With a spring resembling that of a jaguar the Indian threw himself upon the unsuspecting Frenchman, who had replaced his revolver in his holster.

In vain Henri leapt backwards and raised his left arm to ward off the stroke of the Indian's keen knife. The blade glittered in the sunlight. Even as it fell Dacres raised his revolver and fired. Although the distance between him and the Indian was a good twenty yards the Englishman's aim was true. Shot through the head the fellow dropped, writhed convulsively for a few seconds and then lay quiet—as dead as the proverbial door-nail.

"Hold up, old man!" exclaimed Dacres encouragingly, but to his great consternation he saw his companion reel. Before he could get to him the young Frenchman was lying on the ground close to the body of his treacherous assailant.

A rapidly darkening stain on Henri's shirt left no doubt as to the locality of the wound. Deftly cutting away the cloth Dacres found that the knife, partially parried by de la Fosse's left arm, had missed his heart, but had made a fairly deep gash between the third and fourth ribs; while in addition there was a clean cut on his forearm about four inches from the elbow.
