The man now stood intently regarding the dog, with a more sinister expression than usual upon his cruel face, and the boy could scarcely restrain himself from flying away from the spot. Nothing short of his loyal devotion to his patron could have kept him there. At last he said huskily—

"It is useless so to examine this dog, for, strong or weak, you can have nought to do with it, since it belongs to the Señor Diego, and he chooses not that it should be used for your purposes."

De Tivoli uttered a short, hard laugh, and his eyes glittered as he said slowly—

"Ah! yes. It is the Señor Montoro de Diego's dog—-his favourite. And verily it is a fine animal, and powerful, and will do a day's work well for us. That dog of a slave Guatchi has run away, and, dead or alive, yon pet of our Señor Diego shall bring him back to us."

Bautista flung himself down again beside the dog, and threw his arms about its neck, as he exclaimed with the courage of affection—

"No! I tell thee no, Señor Tivoli. Señor Diego has left it to me to guard his dog from doing harm, and I will keep my charge."

De Tivoli's thin lips curled; but ere he could reply other footsteps were heard approaching, and Don Alonzo himself appeared upon the scene.

"How now, De Tivoli," he exclaimed hastily. "Why dost thou waste time? The idle rascal Guatchi hath had start enough, I trow, to breathe the dog e'en now; why dost thou delay?"

"It is but for a minute, Don Alonzo," replied the other coolly. "Yon boy declares that, for Don Diego's sake, it shall not be sent hunting."

"And I," retorted Don Alonzo, "swear by St. Jago that it shall."
