stings sat up straighter in his chair, watching
the shipbuilder's face closely.

"Yes," nodded Jacob Farnum. "Permission has been granted for me to send
our second boat, the 'Farnum,' along with the 'Pollard'--both under the
care of the--"

"The Dad boat," laughed Hastings.

"Yes; that will give us a chance to have the 'Farnum' studied most
closely by some of the most capable officers in the United States Navy.
It ought to mean, presently, the sale of the 'Farnum' to the Government."

"That's just what it will mean," promised Captain Jack, "if any efforts
of ours can make the Navy men more interested in the boat."

"You three youngsters are likely to be at Annapolis for some time," went
on Mr. Farnum. "In fact--but don't let your heads become too enlarged
by the news, will you!"

Hal, quiet young Hal, neatly hid a yawn behind one hand, while Benson
answered for both:

"We're already wearing the largest-sized caps manufactured, Mr. Farnum.
Don't tempt us too far, please!"

"Oh, you boys are safe from the ordinary perils of vanity, or your heads

"What do we think, sir?" echoed Captain Jack, eagerly. "Why, we think

the middies how to run a 'Pollard' submarine."

"How soon are we likely to have to start, sir!" asked Hal Hastings, after
a silence that lasted a few moments.

"Whenever the 'Hudson' shows up along this coast, and the officer in
command of her gives the word. That may be any hour, now."

"Then we'd better find Eph," suggested Captain Jack, "and pass him the
word. Won't Eph Somers dance a jig for delight, though!"

"Yes; we'd better look both boats over at once," replied Mr Farnum,
picking up his hat "And we'll leave word for Grant Andrews and some of
his machinists to inspect both craft with us. There may be a few things
that will need to be done."

As they left the office, crossing the yard, Captain Jack Benson and Hal
Hastings felt exactly as though they were walking on air. Even Hal,
quiet as he was
