, for indeed the torpedo had created fearful havoc. The
full extent of it was not observed until Tom, Ned, Koku and two of the
crew had put on diving suits and approached the hulk. She lay on her
side on the sandy bottom, heeled over somewhat, and when the
investigators had walked around her, as they were able to do, they saw
a second, and even larger hole in the opposite side.

"Two submarines must have attacked her," said Ned, speaking through his
telephone to Tom.

"Either that, or else one sent a torpedo into her, dived, came up on
the other side and sent another."

"Well, let's see if she has any treasure aboard," Ned proposed.
"Wouldn't it be queer if we should discover two treasure ships?"

"More queer than likely," Tom answered. "We've got to be careful going
inside her."

"Why?" asked Ned. "Do you think we'll set off a hidden mine?"

"No, but part of the wreckage might be loosened if we climbed over it,
and we might fall and be pinned down. I've read of divers being caught
that way. We must be careful."

"Do you suppose a German sub did this?" Ned asked.

"I think very likely," Tom answered. "Maybe we can tell if we can
discover the nationality of this craft."

They made their way to a position just outside the gaping hole in the
starboard side of the craft. Evidently; it was, or had been, a tramp
steamer, and the torpedo hole on her starboard side was about
amidships. She must have filled and sunk quickly with two such great
holes torn in her.

Standing near the wound in the steel skin, Tom and his companions tried
to see what was inside. Their portable torches did not give light
enough to make out clearly the character of the cargo carried, and it
was too risky to venture into the mass of wreckage that must be the
result of the explosion of the torpedo.

"Let's try the other side," suggested Tom, and they moved around the
stern of the craft. When they reached the place where the name was
visible Tom raised his electric torch and, in the glow of it, they all
read the painted inscription, Blakesly, New York.

"That's the vessel that disappeared so mysteriously!" exclaimed Ned,
speaking through his instrument. "I remember reading about her. She
sailed from New York for Brest, but was never heard of. At last we
have solved the mystery!"

"Yes," agreed Tom, "but without much avail. We are too late to do any
good."

"Not one of her crew or passengers was ever heard of," went on Ned. "It
was surm
