"And I, in the name of one higher," exclaimed Montoro de Diego, thus unexpectedly making his own appearance on the scene again, "I declare, with Bautista, that it shall not go."

Don Alonzo started slightly, and his face flushed for a moment with ill-restrained annoyance and uneasiness as he saw that set, resolute countenance before him; but he tried to assume an air of carelessness, and to laugh away the matter with an off-hand—

"Why, my mentor, how have you contrived to accomplish the business you had in hand so quickly? What brings you back so soon?"

"Your good genius, I feel inclined to imagine," was Montoro's answer, in tones somewhat quieter than those of his first exclamation. But the fading sparkle in his eyes rekindled as his companion replied irritably—

"Then I wish the meddlesome beast had minded its own business, instead of sending you back here to pull a long face over what I mean to do in spite of it."

As he spoke he walked up to where the dog Don lay tethered, held a strip of cotton cloth to its nose, and then muttering viciously—

"Find him, Don, find him!" pressed his finger hastily on the spring of the dog's collar, and set it free.

The great animal bounded forward. The next instant there was a howl, a moan, and Don lay dying at Montoro's feet; rather, one should say, at Montoro's knees, for the young man had sunk on to them almost as soon as his own fist had fallen with that lightning stroke, and the same hand that had dealt the death-blow was now soothing the poor brute's last agonies. It was Montoro de Diego who had killed it, and yet it was to Montoro's face that the pleading brown eyes were lifted with their last gaze of affection, and it was Montoro's hand that the dying tongue licked with the last breath.

"My poor old Don," muttered Montoro huskily, as he tenderly pressed the side quivering with the death struggle; "poor old Don."

"It's fine for thee to pity the poor brute when it owes its sufferings to thy malice," exclaimed Don Alonzo furiously, and with fingers on the hilt of his dagger, as though they itched to lay his companion beside the animal.
