Jerry cried out to warn his brother. The man whose body he had barely missed in his blind leap was on his feet in an instant. Jerry Utway looked up, straight into the muzzle of a double-barrelled shotgun aimed directly at his head.

“Don’t move!” warned the stranger in grim tones. “You, there, up above—hands up! Come out of those bushes! I’ve got you both covered!”

Jake’s upraised hands appeared above, followed by his face, open-mouthed with surprise. “What’s up?” he asked.

“Never mind. Come down here where I can see you!” There was no mistaking the urgency of that hard voice. “Now, you there, stay right where you are on the ground. Not a move!” The man was dressed in some sort of a blue uniform. He wore a shapeless, broad-brimmed felt hat, and his trouser-legs were tucked into the tops of a pair of leather leggins. “Why, you must be twins!” he exclaimed in astonishment.

Jake slid down the slope in a cloud of dust and a shower of gravel. “That’s right. But what’s the idea of the hold-up?”

“Yes, what’s the idea?” added Jerry. “Look out that gun don’t go off. You better not try anything with us, or you’ll have everybody in Camp Lenape after you, Mister!” The boy’s bold words were somewhat belied by the shakiness of the voice in which they were delivered.

“Oh, from the camp, are you?” Slowly the man in blue lowered his weapon. “Anybody else with you?”

“No, sir. Hear that?” Through the woods drifted the familiar bugle-notes of Swim Call. “We got to get back for swim, or we’ll be missed.”

The stranger chuckled. “I see. Well, guess I won’t keep you.” He grounded the wicked-looking shotgun. “Just a word of advice to you, buddies, before you go. Be a little more careful how you drop on a fellow’s neck right out of the sky. ‘Look before you leap’ is a motto that still holds good.”

Jerry rose and straightened his dusty clothing. “Yes, sir.”
