"Well, while we was coming through the woods we happened to stop a
minute. Then we see this Frenchy sneaking through the woods. We
wondered what was up. Then he vanished. We looked about, some
quiet-like, and on tiptoe, and then we saw this shipmate o' your'n
pry apart some bushes and head in this way. It looked queer to us."

"What did you think was up?" asked Jack.

"Why, as near as we could figger, this was some smuggler's hidin' place,
and we was figgerin' that perhaps Jerry and me would have five 'hundred
or a thousand dollars' reward to divvy up on. It wa'n't--but, anyway,
Jerry an' me are proper glad we stumbled in on this, just the same.
Now, mate, spin yer own yarn."

Hal was on his feet, by this time, and shaking hands with the two
rescuers. Gaston, at the furthest end of the little room, again cowered
against the wall, frightened and surly.

Jack Benson told as much of the story as he thought wise, though he felt

for a couple of years to come."

Gaston heard this with a falling jaw, though he did not venture to say
anything.

"Well, Jerry and me are ready whenever you are, mates," hinted big
Hickey.

Jack nodded, and they filed out, Jerry coming last of all to make sure
that the Frenchman did not lag behind.

"Now, stand up, me bucko," ordered Hickey, seizing the chauffeur's
collar as that worthy crawled through the bushes at the outer end of
the tunnel. "Tryin' to steal submarine secrets, was ye? So some
foreign nation'd have the trick of blowing our battleships to pieces,
and the sailors on 'em? Jerry, wot d'ye reckon 'ud be about right

"Pass him over to me and I'll see," grinned the smaller sailor.

Hickey grasped the frightened chauffeur in both hands, then fairly
