“‘In that case you are at liberty to go to the Bagnio and take him out. Here is my ring.’

“Now, Foster,” continued the Moor, drawing the ring in question from his vest-pocket, “take this. Show it to the captain of the guard at the Bagnio, who will admit you. Tell him that I sent you for one of the slaves. After that your own intelligence must guide you. Go, and God go with you.”

“I will do as you command, Ben-Ahmed,” said Foster; “but I must tell you frankly that I will not—”

“Silence!” thundered the Moor, with a look of ferocity which the amazed midshipman could not account for. “Have you not understood me?”

“Yes, sir, perfectly, but—”

“When a slave receives a command,” cried Ben-Ahmed in rising wrath, “it is his duty to obey in silence. Again I say—go!”

The middy bowed with feelings of indignation, but on reaching the door paused, and again essayed to speak.

“I give you fair warning, Ben-Ahmed, that I will not—”

“Silence!” again roared the Moor, seizing an ornamental box and hurling it violently at his slave, who, dipping his head, allowed it to go crashing against the wall, while he went out and shut the door.

“Well, old boy, I’m absolved from any allegiance to you,” he muttered, as he walked smartly down the garden walk towards the gate; “so if I do a good deal more than your bidding you mustn’t be surprised. But your sudden burst of anger is incomprehensible. However, that’s not my business now.”
