Rather than waste time arguing, Don Ramon flung off into a neighboring room. He returned presently with a pair of white duck trousers, and Carl climbed into them. They were too long and too narrow, but the Dutch boy contrived to make them serve.

"Now, ton," said Carl, "ged der key by der front gate und lead der vay."

The don took a key from the drawer of the table.

"Come, amigo," said he, hurrying from the door.

"Id's a funny pizness," remarked Carl, following, "dot dis Carlos feller vouldt leaf der door oben und lock der gate."

"The gate locks itself when it is closed," explained the don.

"I don'd t'ink, anyvay, dere iss mooch use being in some takings aboudt der poat," proceeded Carl, as the don unlocked the gate. "Dot Carlos feller vill haf his hants full pulling der vool ofer Modor Matt's eyes."

"You do not know Carlos as well as I," answered Don Ramon ominously. "He is plausible, he has many tricks, and then he is impersonating me! Motor Matt must know me by name, although I have not the pleasure of his personal acquaintance. I am fearing the worst, ah, yes, the worst!"

The gate clanged shut behind them and the don and Carl raced for the International Hotel. Matt and Dick stayed at the hotel while they were ashore. Carl had not seen either of his chums at supper, and he had not spent much time looking for them. The serenade was uppermost in Carl's mind, and he was afraid Matt or Dick might propose something that would interfere with his plans.

In the hotel office they learned that Matt and Dick had gone out to the submarine early in the evening to arrange some stores that had been taken aboard. They had not come back, so the inference was that they were staying the night on the craft.
