ept his hands up inside his wide sleeves. Now Farley
leaped forward as he shouted:

"Look out, Darry! He has a knife!"

Farley attempted to seize the Chinaman's wrist, for the purpose of
disarming the yellow man, but Dave swiftly threw the Chinaman around out
of Farley's reach. Then, with a lightning-like move, Dave knocked the
knife from Chow Hop's hand.

"Pick that up and keep it for a curio, Farley," directed Dave coolly.

In another twinkling Darrin had run the Chinaman up against the wall.

Smack! biff! thump!

With increasing force Dave's hard fist struck the heathen in the face.

"Now stand there and behave yourself," admonished Midshipman Dave,
dropping his hold on the yellow man's collar, "or we'll stop playing
with you and hurt you some."

The scowl on Chow Hop's face was ominous, but he stood still, glaring at
Dave.

"Chow, what can we do to bring this man out of his sleep!" asked Dave
coolly, and almost in a friendly tone.

"Me no sabby," sulked the Chinaman.

"Yes, you do," retorted Dave warningly. "Now, what can we do to get our

paper from the other room."

Dalzell was quickly back with the desired item. On the paper Dave wrote
a name and a telephone number.

"It's near the end of the doctor's office hours," murmured Dave. "Go to
a telephone and ask the doctor to meet you at the corner above. Tell him
it's vastly important, and ask him to meet you on the jump."

"Shall I tell him what's up!" asked Dan cautiously.

"Yes; you'd better. Then he'll be sure to bring the necessary remedies
with him."

Dan Dalzell was off like a shot.

Chow tried to edge around toward the door.

"Here, you get back there," cried Dave, seizing the Chinaman and
slamming him back against the wall. "Don't you move again, until we tell
you that you may--or it will be the worse for you."

Ten minutes passed ere Dan returned with Dr. Lawrence.

"You see the job that's cut out for you," said Darrin, pointing to the
unconscious figure in the bunk. "Can you do it, Doctor?"

The medical man made a hasty examinatio
