together," proposed Jack. "I don't like
the idea of separating while we're in a strange town."

"Perhaps the captain can tell us where we can get some English papers,"
ventured Jimmie. "We'd like to get the latest news."

Wheeling in his chair the captain bawled out an order in Dutch. A waiter
came bustling up with an air of deference. Evidently he knew the captain
and understood that no delay would be tolerated.

A few words were rapidly spoken, whereupon the waiter hastened away to
return presently with several newspapers. These were spread upon the
table before the boys, who began a perusal of their contents.

"Gee whiz!" exclaimed Jimmie, glancing at the headlines of the paper
which had fallen to his lot. "Listen to this--three vessels sunk in the
mouth of the Mersey river by a German submarine identified as the 'U-13.'
Then there's been two vessels sunk at the mouth of the Thames!"

"What sunk them?" inquired Harry.

"It says here that they were sunk by a German submarine. In each case the
diver has been identified as the 'U-13' by the crews of the ill-fated
vessels. Now, that's going some!"

"Let's see," pondered Harry, "the Thames is the river leading to London,
while the Mersey is the river leading to Liverpool."

"Right you are, Old Scout, go to the head of the class!"

"Hush, Jimmie, no nonsense!" cautioned Ned.

"What I was thinking about," continued Harry, "is the distance a boat
would have to travel to get from one place to the other. It must be all
of seven hundred miles around Land's End. A boat would have to be speedy
to cover that distance so quickly!"

"How quickly?" demanded Jimmie. "The paper says the three ships were sunk
at the Mersey on Wednesday morning. Those at the Thames, or rather 'off
Margate,' as the article states, were sunk Thursday afternoon. That
wouldn't be such an impossible feat after all!"

"Twenty miles an hour sustained speed for about twenty-eight hours is
running along at a pretty good clip, just the same!"

"Well, the vessel did it!" declared Jimmie. "The paper says that about
six o'clock Wednesday morning the Wanderer, a vessel laden with
foodstuffs from Australia, was hailed by the crew of a submarine. They
were permitted to take to the small boats and then the Wanderer was
torpedoed, going down at once. The submarine was positively identified as
the 'U-13.' Then the other paragraph says that at about eight o'clock on
Thursday evening the steamer Adventure from
