"Thank you," said Matt, "once was enough."

As the submarine came along on the lee side of the war vessel, the big ship slowed her pace. Presently both craft were jogging along as companionably as a lad and his lass going to market.

"Señor," called Sandoval through a megaphone, "I beg your pardon ten thousand times."

"Vat's dot?" muttered Carl, with bulging eyes. "Can I pelieve vat I hear? Ten t'ousant dimes he pegs Modor Matt's bardon. For vy?"

"Why do you do that, captain?" asked Matt.

"Because of the little mistake. I made it. When Captain Enrique Sandoval makes a mistake he admits it like a man."

"What was the mistake?"

"Why, this, that your wireless instrument was not the one that claimed the submarine was my war ship."

Matt was puzzled.

"How did you find that out?" he asked.
