"Captain Nemo, Jr.," muttered the captain. "Carramba! A fictitious name. There is a story about a Captain Nemo. Why do you talk to me like that?"
"I am telling you the truth!" answered Matt. "Will you tell me your name, sir?"
"Why do you wish to know that?"
"So I may report this conversation to the naval officer aboard the Grampus. He will enter it in his log, which, at the end of this cruise, will be submitted to the navy department of our government."
The captain's eyes glimmered like coals.
"So!" he snapped. "You think me afraid? Ah, ha! I am Captain Enrique Sandoval, of the Chilian war ship Salvadore. Report it. What is it to me? Now, if you please, have you a wireless telegraph instrument aboard the submarine?"
"We have. What of that?"
"Then you admit it!"
"I don't know why I shouldn't admit it," answered Matt coolly.
"Why have you a wireless machine on your boat?" went on the captain.
