e and aft on account of it. I'm
through with him after this cruise. I've only kept him on as long as I
have because Mr. Parmalee wanted it so. But he finds another berth as
soon as we reach New York."

"I've noticed him talking to some of the men a good deal," remarked
Tyke.

"That's another thing that's worried me," said the captain. "Up to
now, Ditty has always been a good bucko mate and has kept the men at a
distance. Did you see the man I knocked down the other day when he
started to give me some back talk?"

"Yes," grinned Tyke. "You made a neat job of it. Couldn't have done
it better myself in the old days."

"But the peculiar thing about it," continued the captain, "was that I
had to do it although the mate was a good deal nearer to the fellow
than I was. Ordinarily, Ditty would have put him on his back by the
time he'd got out the second word. But this time he had paid no
attention, and I had to do the job myself."

"Well, what do you make of it all?"

"I don't know what to make of it, and that's just what's troubling me.
If I could only get to the bottom of it, I'd make short work of the
mystery."

"How's your second officer, Rogers? Is he a man you can depend on?"

"He's true blue. A fine, straight fellow and a good sailor."

"That's good."

"I wish he were mate in place of Ditty," muttered the captain.

"Well, he ain't," replied Tyke. "An' to make any change jest now with
nothing more'n you've got to go on, would put you in bad with the
marine court. We'll jest keep our eyes peeled for the first sign of
real trouble, and' if them skunks start to make any we'll be ready for
'em."

"I wonder what the matter is with Drew and Parmalee over there!"
exclaimed the captain suddenly. "More trouble?"

Tyke followed the direction the captain indicated and was astonished to
see that the young men seemed to be on the verge of an altercation.
Their faces were flushed and their attitude almost threatening.

The captain hurried toward them, and Tyke hobbled after him as fast as
he was able.

The tension between Parmalee and Drew had been slowly but steadily
tightening. Little things, trifles in themselves, had increased it
until they found it hard to be civil to each other. In the presence of
Ruth and the two older men, they suppressed this feeling as much as
possible; and except by Ruth it had been unsuspected.

The purest accident that afternoon had brought the matter to a crisis.
