mail if he found he could not make good use of
the knowledge he had stolen."

"The wretch!" cried Margaret. "Do you suppose he hopes to snatch from
you the discovery of the pole?"

"That seems obvious," replied Roland, "and it's what Sammy thinks. It
is the greatest pity in the world he was not discovered before he got on
the Dipsey."

"But what can you do?" cried Margaret.

"I cannot imagine," he replied, "unless I recall the Dipsey to Cape
Tariff, and go up there and have him apprehended."

"Couldn't he be apprehended where he is?" she asked. "There are enough
men on board to capture him and shut him up somewhere where he could do
no harm."

"I have thought of that," answered Roland, "but it would be a very
difficult and delicate thing to do. The men we have on board the Dipsey
are trusty fellows--at least, I thought so when they were engaged--but
there is no knowing what mutinous poison this Pole may have infused into
their minds. If one of their number should be handcuffed and shut up
without good reason being given, they might naturally rebel, and it
would be very hard to give satisfactory reasons for arresting Rovinski.
Even Gibbs might object to such harshness upon grounds which might seem
to him vague and insufficient. Sammy knows Rovinski, I know him, but the
others do not, and it might be difficult to convince them that he is the
black-hearted scoundrel we think him; so we must be very careful what we
do."

"As to calling the Dipsey back," said Margaret, "I would not do it; I
would take the risks."

"I think you are right," said Clewe. "I have a feeling that if they come
back to Cape Tariff they will not go out again. Some of the men may be
discouraged already, and it would produce a bad impression upon all of
them to turn back for some reason which they did not understand, or for
a reason such as we could give them. I would not like to have to bring
them back, now that they are getting on so well."

In the course of the morning there came from the officers, men, and
passenger of the Dipsey a very cordial and pleasant message to Mr. Clewe
and Mrs. Raleigh, congratulating them upon the happy event of which
they had been informed. Sarah Block insisted on sending a supplementary
message for herself, in which she was privately congratulatory to as
great an extent as her husband would allow her to go, and which
ended with a hope that if they lived to be married they would content
themselves with doing t
