Shaking and terrified, Bob nevertheless stood motionless, partly because he did not know what else to do, but mainly because the fellows on either side of him had not stirred. He dug his teeth into his under lip to keep back a frightened whimper, and then of a sudden the clear, high voice of Mr. Curtis rang out above the deafening din and turmoil:

“Troop Five prepare to form double riot wedge! One!”

Instinctively Bob leaped two paces forward and a little to the right. In like fashion the others darted to their positions with the swift precision of machines. Not a scout failed. Even Bennie Rhead, frightened as he was, made no mistake, and in a trice the wedge was complete.

“Two!” shouted the scoutmaster.

Down swung the staves, interlocking in a double barrier of stout hickory backed by equally sturdy muscle. The scoutmaster had barely time to place himself at the apex of the wedge before the mob struck it.

“Hold fast, boys!” he cried. “Brace your feet and don’t let them break the line!” He flung up both arms in the faces of the maddened throng. “Stop!” he shouted. “You can’t get out this way. The stairs are impassable. Stop crowding! There’s no danger if you keep your heads. The fire-escapes are in good order. The windows–”

The rest was choked off by the crushing weight of the mob dashing against the barrier. Even in the second row Bob felt the double line shake and give under the strain, and instinctively he dropped a shoulder against the pressure and spread out his legs to brace himself. MacIlvaine noticed what he was doing, and shouted to the others to follow Bob’s example; and presently the line steadied and held. Then a shrill whistle cut through the clamor, stilling it a little and making it possible to hear the stentorian voice of Captain Chalmers from somewhere in the rear of the crowd.

“You can’t get out by the stairs! There are fire-escapes at both front and rear. Ladders will soon be raised to the other windows. There’s no danger if you only keep your heads. Stop crowding and form in line at the windows. Scouts will see that these lines are kept and that the women and children are taken out first.”
