"Bang!"
"What luck?"
"Squarely in the center. That's what I should call a bull's eye," announced Dan Davis triumphantly. "Am I right, sir?"
"Yes; you hit the mark all right. It may have been a chance shot."
"I think not, sir. I will see if I can do it again."
Dan applied his eye to the finder. An instant's hesitation, then there followed the sharp report of the dotter.
"Once more in the center, sir. Shall I fire again?"
"No. You've sunk the ship, young man. You have put the enemy out of business. You are not only going to make a splendid gunner, but you are far above the average already."
Ere Dan could express his thanks the bugle blew, piping gun crews down to other duties.
