But Ken and Hal were too eager to catch a tarpon to troll one at a time, so once more they let their lines out. A tarpon took Hal's bait right under the stern of the boat. Hal struck with all his might. This fish came up with a tremendous splash, drenching the boys. His great, gleaming silver sides glistened in the sun. He curved his body and straightened out with a snap like the breaking of a board, and he threw the hook whistling into the air.

Before Hal had baited up, Ken got another strike. This fish made five leaps, one after the other, and upon the last threw the hook like a bullet. As he plunged down, a beautiful rainbow appeared in the misty spray.

"Hal, do you see that rainbow?" cried Ken, quickly. "There's a sight for a fisherman!"

This time in turn, before Ken started to troll, Hal hooked another tarpon. This one was not so large, but he was active. His first rush was a long surge on the surface. He sent the spray in two streaks like a motor-boat. Then he sounded.

"Hang on, Hal!" yelled George and Ken in unison.

Hal was bent almost double and his head was bobbing under the strain. He could not hold the drag. The line was whizzing out.

"You got that one hooked," shouted George. "Let go the reel--drop the handle. Let him run."

He complied, and then his fish began a marvelous exhibition of lofty tumbling. He seemed never to stay down at all. Now he shot up, mouth wide, gills spread, eyes wild, and he shook himself like a wet dog. Then he dropped back, and before the boys had time to think where he might be he came up several rods to the right and cracked his gills like pistol-shots. He skittered on his tail and stood on his head and dropped flat with a heavy smack. Then he stayed under and began to tug.

"Hang on, now," cried George. "Wind in. Hold him tight. Don't give him an inch unless he jumps."

This was heartbreaking work for Hal. He toiled to keep the line in. He grew red in the face. He dripped with sweat. He panted for breath. But he hung on.
