"We're making pretty good time," said Nat pleasantly, for he often addressed the passengers, many of whom had formed a liking for the lad.

"Oh, yes, ve go fast enough," replied the German, who spoke with quite an accent. But he answered so gloomily, that the vessel might as well have been going backward, for all the satisfaction he derived from her speed.

"We'll soon be in port," went on Nat. "I suppose you'll be glad to get on shore. It's quite rough on account of the wind."

"Oh, it makes not so much difference to me," was the answer, and the youth did not smile. Indeed, he hardly lifted his face to glance at Nat, yet he did not seem to resent being spoken to.

"It's a nice day," went on the young pilot.

"Yes, I suppose for dem vot likes der vedder," came the answer. "But, ach——" and then the German murmured something to himself in his own language.

"I guess he doesn't feel well, or else he doesn't want to talk," thought Nat, as he passed on. "Maybe he's a bit seasick, though there's hardly any motion to-day."

Nat passed on, to attend to some of his duties. When he came back, about an hour later, the German youth was in the same place, moodily staring down into the water.

"I wonder what ails him?" thought Nat. "He acts queer. But that's the way with some Germans, the least little thing makes them moody, and then, again, they're as jolly as can be. But I suppose we are all queer, in one way or another."

He was half-tempted to speak to the youth again, as he passed him, but he did not want to be thought too forward, so he said nothing, nor did the German appear to notice our hero.
