we to do when we get there?"

"Events will have to shape themselves," declared Lord Hastings. "It is
impossible to foretell anything."

Jack re-entered the room at this moment, and the three held a
consultation, Edwards meantime steering the course that Lord Hastings
had given him.

And so the submarine continued on its course beneath the sea for the
rest of the night, running slowly.

At eight o'clock in the morning, Lord Hastings decided to go to the
surface for a look around. He stopped for a moment, however, just below
the surface, with the periscope protruding slightly above the water and
took in his surroundings.

In the distance he made out a coast line, which, according to his
calculations, should be the coast of Belgium.

"We should not be more than an hour's run from Ostend," he told the
lads. "We'll continue on the surface."

The submarine was brought clear of the water and continued on her way.

But there was to be no need of the submarine putting into Ostend. Half
an hour after the vessel had been brought to the surface, Frank, who was
alone for the moment upon the bridge, made out a second submarine
approaching. Quickly he summoned Lord Hastings and Jack.

"Well," said Lord Hastings, "here is where we have to do some tall
talking, as the Americans would say. He's headed directly for us."

It was true. The submarines were approaching each other rapidly.

The enemy slowed down, and in response to Lord Hastings, the captured
vessel did likewise. A voice from a figure on the bridge of the second
vessel came across the water.

"Who are you?"

"U-16," answered Lord Hastings, who had gone through the former
commander's papers carefully, "Bernstorff, commanding."

"Bernstorff," came the surprised response. "Where is Captain
Tarlenhein?"

"If you will come aboard, I will explain," shouted Lord Hastings.

"Very well."

A few moments later a small boat left the side of the other vessel and
came toward the U-16.

"Now, boys," said Lord Hastings quietly, "keep a tight rein on
yourselves and leave the talking to me. Say nothing unless you are
addressed. It would not do for us to be tripped up. We would all be put
to death as spies."

The boys nodded their understanding of this order.

"We'll be as mum as a couple of oysters, sir," declared Frank.

"I wouldn't know what to say, anyhow," agreed Jack.

"Sh-h-h," whispered Lord Hastings. "Here he comes."

The small boat scraped the side of the
