e able to stand upright.

"What's the matter, Jimmie?" cried Ned, as he scrambled to his feet. "Is
it a whale, or did you nearly have a collision?"

"Collision is exactly the word!" declared the other. "I saw the masts of
a ship standing right in our path. I got this little craft turned just in
time! That's what we get for blundering along so fast!"

"What kind of a ship is it?" asked Frank, peering from one porthole after
another. "Are you sure it was the mast of a vessel?"

"Why, certainly, I am sure!" was Jimmie's decisive answer. "Don't I know
a ship's masts? I surely do!" the lad answered his own question.

"Let's swing around and see what it was," proposed Frank.

"All right, turn the deflecting rudders and down we go!"

Swinging in a broad circle, the submarine was directed downward to a
level equal with that of the hull of the ship, whose masts had so nearly
proven disastrous to the boys. As the craft sank deeper the crew watched
with a great deal of curiosity from the thick glasses over the portholes.
Carefully they studied every detail of rig.

Although the sunshine penetrated to some distance below the surface, they
found that at the depth where the hull lay a semi-twilight prevailed. The
upper portions of the masts had been clearly visible, but the decks lay
in a haze that prevented their seeing well.

"Looks like the ship is almost new!" stated Frank.

"Possibly it has been sunk only a short time," ventured Jack.

"Can you make out what ship it is?" asked Ned.

"Wait a minute until we pass the stern again," said Frank.

"I can see it!" declared Harry in a moment. "It's the Wanderer of Sydney!
That will be an Australian vessel!"

"And that great gap in the port side indicates that the sinking was the
work of our namesake!" stated Ned. "This is another victim of the German
'U-13'. Probably it is only one of many!"

"No wonder the other fellows don't seem inclined to be any too sociable!"
said Jack. "They really cannot be blamed!"

"Right you are, Jack," responded Ned. "When anyone hits at the pocketbook
we're apt to consider everybody under suspicion."

"Let's get closer and examine the damage done by the torpedo," suggested
Frank. "I'd like to observe the effects of the attack."

Shortly the misnamed "U-13" was creeping alongside the hull of the sunken
vessel. Jimmie handled the wheel dexterously, ever alert for possible
danger. Harry stood by the engines, ready at a moment's notice to ass
