“And you may, indeed, help us,” interposed Isabel, fixing her dark eyes on the missionary. “What shall we do on board an English brig, with no one to understand us. But will not the senhor be too weak if we leave to-morrow?”

As she stood there, with the stars shining upon her, and the fire-flies playing like an aureole round her head, it occurred to Hughes that he was strong enough to follow her anywhere. The missionary looked at him inquiringly.

“Every day will bring me strength,” he replied; “and I shall be very glad to get to the sea once more. Senhor Dom Francisco Maxara, I accept your kind and generous offer, with many thanks.”

“And I also,” joined in Wyzinski.

“Then, Senhor Commandant, we will start to-morrow evening. I shall leave my staff here until the surveys, estimates, and plans be completed, and you shall have your revenge when you come home.”

“All shall be in readiness,” replied Mujaio, as he took a whistle from his neck, and sounded a shrill call. A boat shot across the stream from the fort; the noise of the oars straining in the rowlocks was heard, and the bowman jumped ashore, holding the boat’s painter in his hand.

“Good-night, gentlemen,” said the noble. “I shall have much business to transact with the Senhor Commandant to-morrow, and may not see you. My daughter, Dona Isabel, will hope to have that pleasure in my absence. The smaller of the two boats allotted us you will look upon as yours.”

Moving towards the river, his daughter on his arm, the stately Portuguese took off his broad-brimmed hat most courteously. Senhor Mujaio followed, having first handed the missionary the silver whistle.

“When you require the boat you have only to use this. Good-night, gentlemen.”

A dark spot shot off from the bank into the starlight; the noise of the oars was again heard, and then the sound of a merry Portuguese air, in the chorus of which even the boatmen joined, though the soft, silvery female voice told who was the principal singer. Then the dark shadow thrown across the river received the boat, and all was silent. With a sigh of gratification, Hughes threw himself back on the cushions.
