se to his feet. He balanced himself against the
wall while he raised one foot and gave three distinct slaps on the floor
with the sole of his shoe. Both listened sharply.

"Bob, Bob White," came the answering call through the partition.

"Who's there?" called Harry in a voice trembling with excitement.

"Bob White, St. Louis," came the muffled reply.

"Good gracious," was Harry's startled comment. "Bob White, St. Louis.
Then they've got Jack and Tom and Frank cooped up here."

"That's awful," groaned Arnold. "What shall we do?"

"If it is really a Boy Scout, we'd better try to help him."

"If we only were not tied. How can we get loose?"

"There's only one way that I can see," stated Harry. "If you will rise
to your feet so that I can get at your hands with my teeth, I'll try to
untie that rope that holds you. Then you can untie me."

"But that isn't a rope," protested Arnold. "That's a snake skin and it's
off the snake that nearly struck you. You wouldn't think of biting on
that. You just couldn't do it. I couldn't."

"That's what I thought, so I suggested that I do it."

"What do you mean?" flashed Arnold. "I guess I can do anything you can.
I've never been stumped yet and I shall not begin now."

"Never mind the argument, let me get at your bonds."

"Not yet. I'll untie yours, but you're not going to untie mine with your
teeth. Tom got kicked in the jaw, Jack got shot and you got your wrists
cruelly burned on this trip. It's no more than fair that I should have
some of the discomforts of this experience."

"Well, then, hurry up. That fellow may be in trouble."

But a few minutes were required for the boy with his strong, white teeth
to so loosen the knot hastily tied by Lopez as to render possible the
free movement of Harry's arms. After swinging his hands vigorously a few
moments to restore circulation, Harry then performed a similar office
for his chum, but not, however, with his teeth. The experience was
almost too much for Arnold, who for a time threatened to be ill from the
suggestion of biting the thongs.

When both were freed they next gave their attention to the lad on the
opposite side of the partition. Their signals had been constantly
answered with the plaintive, "Bob, Bob White." "This door's locked on
the other side," declared Harry, after trying the latch. "I'll bet it's
got a bar across."

"Then the only thing to do is to batter down the partitions," declared
Arnold. "Is it lath and
