"See, Frank! What is the fellow going to—— Look out!"
On the steamer Flynn had been seen to hastily unbutton his mackintosh, jerk something bright out of his hip pocket and point it toward the yacht.
It was a revolver.
Jack Diamond realized the desperate fellow's purpose, and he caught hold of Frank Merriwell and gave him a push that threw him to the deck beside the wheel.
There was a flash of fire from the revolver, a puff of smoke, and then a bullet whistled over the yacht, striking the water beyond.
"Well, of all the foolhardy, cowardly tricks, I believe that takes the premium!" said Frank, as he arose and grasped the wheel again. "That man is drunk or crazy!"
The moment Flynn fired, Snell took to his heels and scudded out of sight, disappearing on the other side of the steamer. Flynn hastily put up his revolver, shook his fist toward the yacht, and then followed Snell, both of them getting out of the way before anyone, attracted by the sound of the shot, came aft to investigate.
The big paddlewheels of the steamer were in motion
again, and she was forging on her course, as if nothing had happened.
Frank brought the White Wings round and set his course to follow as closely as the wind would allow. In a short time the steamer was almost out of sight in the thin mist that hung over the water where there was no fog.
