"Let's get out of this, boys!" he called, "every fellow turn, and streak it as fast as he can. And get behind trees as quick as you can, because—"

They had already started to obey the scout master, and possibly had covered a few jumps when it seemed that the very earth shook and quivered under them, as a fearful roar almost deafened every boy.

Just as you have seen a pack of cards, made into tent shape in a curving row, go falling down when the first one is touched, so those seven scouts were knocked flat by some concussion of the air.

They had hardly fallen than one and all scrambled to their feet, and fled madly from the scene, as if fearful lest the whole end of the island might be blown up behind them, and catch them in a trap from which there could be no escape.

Either by rare good luck, or some sort of instinct, the seven lads managed to keep pretty well together as they ran. Not a single fellow dreamed of allowing himself to get separated from his comrades. It seemed to be a case of "united we stand, divided we fall," or "in union there is strength."

If in their mad rush some of the boys collided with trees, or stumbled over obstacles that they failed to discover in time, they were not of a mind to let such trifles interfere with their making record time.

In such cases it was only necessary to scramble erect again, and put on a little extra spurt in order to overhaul their comrades.
