"Come on, Jack; let's be moving," said Frank impatiently. "There is no use staying here all day. Hurry up."

"Now you just hold your horses," replied his chum. "We'll get there soon enough—maybe a little too soon, so far as we know."

Nevertheless the lads wasted no further time in talk and five minutes later the two were rowing shoreward in a little boat.

As they rowed along, they saw several other under-the-sea craft at anchor and upon the bridges of one or two stood officers. These saluted as the boys passed, but none so much as hailed them.

"These German uniforms seem to be pretty good things," Frank remarked in a low voice. "Guess they carry the entrée any place in the town."

"We'll see," returned Jack briefly.

Fifteen minutes later they reached a landing and climbed ashore. Then they tied the little boat up, against their return, and started down the first street.

"Pretty likely looking town, this," declared Jack, as his gaze roved about.

"Yes," Frank agreed, "but you can still see the marks of the German shells that struck during the siege."

They looked around with interest—though not so curiously as to attract attention—and continued along the street.
