Yet the submarine boy was undismayed and confident, until, out of the corner of one eye, he saw Radwin rising and advancing cautiously to close in.
Young Benson's opportunity came at just that instant. Smack! He landed his right fist in the driver's face, almost dazing him. With the left fist Jack struck himself free.
But Radwin was just upon him as the boy turned.
"No, you don't!" mocked Captain Jack, ducking down, kangaroo-fashion.
"Day-day!"
That low crouch and the following spring had carried the submarine boy just under Fred Radwin's outstretched right arm.
And now, Jack Benson, being past both of his assailants, took refuge in discreet flight, in fact, he ran down the street with about every pound of human steam turned on.
"Come on!" snarled Radwin, setting the sprinting pace. "We've got to catch that rascally boy, and mighty quick, too!"
This block or two of the street appeared to be deserted. There was no telling, however, how soon the submarine boy might run into two or three real men who would take his side in any scrimmage that was due.
Though Radwin had the first start after Jack, and was running well, the driver, a long-legged fellow with splendid "wind" soon passed his leader.
Jack realized that he was in danger of being caught, and tried to put on a greater burst of speed. Yet the driver came closer and closer.
