"Stop, or I shall shoot!"
Frank flourished the revolver, running as hard as he could in pursuit.
The command was not obeyed.
In an attempt to frighten the creature into obeying, Frank fired two shots into the air.
Still the thing ran on.
"Well, I see I must catch him," muttered Merriwell.
He set his teeth and made wonderful speed over the uneven ground. Never in any college sprinting match had he made such speed. He was determined to overtake that hideous thing and solve the mystery of the island.
Frank soon saw he was gaining. The creature looked back and saw the same, whereupon it seemed to increase its efforts.
But, although the monster was a swift runner, it could not get away from Merriwell. The cove was passed, and the race continued up the rise toward the big building above.
