a formal fight,
at the Naval Academy, unless you are prepared to defend your side
before a class committee. Now get up and take yourself away--you
infamous hound!"

Tony, in the meantime, had swiftly vanished. The Greek's change
of front, in denying his charge against Brimmer, had been prompted
by craft.

"Meester Brimmer, he pay me, now, not twenty dollars, but all
the money he have, and all he can get," chuckled the rascally
Greek. "Otherwise, he be afraid I tell too much, and he get the
double-queeck out of the Naval Acadeemy!"

Brimmer, boiling with helpless rage, got up and made off as quickly
as he could. He would have fought, on the spot, but knew that
with one eye closed, and giving him great pain, he would be but
a football for the strenuous Darrin.

And now Dave bent over his chum, who, still unconscious, was breathing
heavily.

"He's in no immediate danger," breathed Darrin, in great relief.
Then, hearing wheels, he stepped to the end of the alleyway.
As if in answer to his prayer the vehicle turned ont to be a
cab, and without a fare.

"Driver, I need you here!" called Dave, and the cab rolled in
at the curb.

"Follow me," directed Darrin, leading the way up the alley

Catching sight of the prostrate midshipman the driver grinned.

"No, he's not intoxicated!" flashed out Darrin half angrily.
"This is all a trick. Help me lift him into your cab. Then drive
us to the best physician in the town."

Dan was propped in place on the back seat, Darrin beside him.

"Give me the card of your stable, driver," Dave requested. "I
haven't money enough to pay you, but I'll write and have my father
send you the amount of your bill."

"That'll be all right, sir," nodded the driver who knew the ways
of midshipmen, and who also knew that such a "risk" was a safe one.

A few minutes later the cab stopped before the residence of Dr.
Stewart.

"See if the doctor is in," directed Darrin.

The physician was at home, and not engaged. So Dave and the driver
carried Dan into the medical man's office.

"Too bad!" murmured the physician. "Intoxicated, eh?

"No, sir," responded Dave quietly, "and that's one of the things
I wish you to note positively, so that you can be prepared to
certify if necessary. This is the stuff, I believe, with which
my friend was drugged."

Dave passed over the vial Tony had handed him. Dr. Stewart smelled
the contents, then touched the bottle lightly to his tongue.
