To all this Katie gave no heed. She had discovered a small tank on the pump. This she had filled with gasoline. Now she was fitting the knot of the short rope into its place. If this pump worked like an outboard motor she could start it. And then—

Florence was thinking all this when with a start, her mind was brought back to Mike.

“Think y’re smart, don’t yer?” There was a dangerous glint in his eye. He took a step toward her—another, and another. “Think I’m a guttersnipe, don’t y’—a tough city guy? Well, that’s what I am. I—I’ll show y’.” He took one more step.

“No!” Florence tried in vain to steady her wildly beating-heart. “No! That’s not what I think at all. I don’t care where you came from nor what you’ve been. I only know what you are now. What you’re doing. Lying down on your job—leading all these boys the wrong way. You’re ungrateful—you—”

“Think yer smart,” Mike stepped closer.

“Don’t do that, Miss,” a wavering voice came from the line. It was the smallest, most timid boy of the lot who spoke. And yet—he had courage.

Swallowing hard, the girl tried to speak. Words would not come. Mike’s fists were clenched hard as he moved one step nearer. He was closely followed by Tony.

“Don’t let him, Miss,” came in that same wavering voice.

And then the thing happened. Three times, all unknown to Florence, the powerful Katie had pulled the rope that turned the wheel of the strange pump that looked like an outboard motor. All that time Florence had held the hose in her hand. Once again Katie gave the rope a vicious jerk. And then! Was it like an outboard motor? Like ten outboard motors all in one the thing thundered—the hose in Florence’s hand writhed and twisted like a snake. It swung half around her neck, tripped a boy passing down the line, stiffened like a bent and twisted gas pipe, then shot forth a stream that would have gone forty feet if it had not encountered an obstacle. That obstacle was Mike’s broad chest!

Thrown off his balance by that irresistible force, with the swiftness of light, Mike spun half-way round, rose in air, then went plunging into space. When space rejected him, the glad, cold waters of the harbor opened their arms to receive him!
