McClure had jumped up on the conning tower and was hugging the periscope
pole. There was a moment's silence before he spoke.

"A little short, boys," he called. "Elevate just a little more---you've
nearly got the range."

Again the gun crew leaped into action.

"Hurry, boys! he sees us now and is beginning to submerge!" yelled the
young lieutenant as he followed the U-boat through his glasses.

Again "Roosey" spoke, and this time with an emphatic "crack" that boded
ill for any luckless human who might get within the line of its
screaming shell fire.

"O-o-o-oh, great!" cried Lieutenant McClure an instant later as he
peered more intently through his glasses.

Of a sudden the periscope disappeared from the crest of the sea as
though wiped out completely by the explosion of the _Dewey's_ shell.

"No doubt of it, boys; you ripped off that periscope," announced
McClure, with an air of finality.

At their commander's words the gun crew burst into cheers. The
submersible's wireless was singing out a message of good cheer to
the American fleet. It was only too evident that the enemy U-boat had
been crippled and put completely to rout by the daring maneuvers and
deadly gunfire of the _Dewey_.
