“You heard what I said, Gaines?” went on Bob, his voice pitched low but carrying an emphasis that lifted it above the hum of the motor.

“I heard you, Bob,” replied Gaines.

“Either obey the order or give up the wheel to Clackett.”

Brought directly face to face with the issue, Gaines hesitated. The sharp eyes of the don noted the effect the masterful young man’s words were having on Gaines.

“Don’t you do it, Gaines,” said the don coolly. “Think of the money you’re to get. Bob Steele has not the courage——”

“Don’t talk foolish!” growled Gaines. “Bob’s got more pluck in a minute than any of the rest of us have in a year. I know him.”

“He hasn’t the courage to go to the Izaral,” growled the don.

“He’s only off’n his course a little about that,” answered Gaines.

“Will you obey orders, Gaines, or leave your post?” asked Bob.

“He’ll obey my orders,” flashed the don, “and he’ll stay right where he is and hold to his present course.”
