The captain waved the glasses back with something like a shudder.
"I am sorry," he said, quietly. "The poor chap was only doing his duty. I aimed at metal and not human bodies. I hope he is not much hurt."
He turned to the rail again, touched the spring, and the gun slowly sank out of sight, the section of the deck that concealed it slipping into place again with a click. Putting on his coat he entered the cabin, leaving the boys in possession of the glasses. For some time they were greatly interested in watching, turn by turn, the proceedings on the deck of the gunboat, but finally the _Mariella_ made such good use of her heels that even with the glasses, they could make out nothing but the outlines of the Spaniard.
When they turned again to the deck of their own steamer, they were surprised to see that it had once more resumed its usual appearance. The armed men had disappeared, the second mate paced the bridge, and only the lookouts occupied the decks. It was now twelve o'clock, and eight bells sounded clearly on the still, tropical air. The boys recollected for the first time that they had had no breakfast, just as Captain Dynamite stuck his head out of the cabin door.
"Come on, lads," he called, cheerily; "sure we've let the Spanish terrier cheat our stomachs."
The exciting events of the morning had not impaired the boys' appetites, and they promptly responded to the call. When they went on deck again only a speck on the horizon marked the pursuing gunboat.
"Few of their old tubs can measure paces with the old _Mariella_," said the captain, with satisfaction, as he swept the sea with his glasses.
"She looked as if she had once been a pleasure yacht," said Harry.
"So she was, my boy. The Spaniards bought her from a New York millionaire, but she was an old model then, and they have top-hampered her with armor and guns until they have knocked what little speed she had out of her. We'll not even see a whiff of their smoke in half an hour."
"O, sure she will. She hopes to trap us down the coast. See, there are the shores of Cuba."
The boys turned quickly as he pointed over their starboard bow and saw a low dark line in the distance.
"Hurrah for what?" asked the captain, smiling at the enthusiastic boy who swung his cap as he shouted.
