"You are not sailing her, if you don't take her in where I say," the intruder declared fiercely. His eyes were bloodshot and his teeth closed together with a snap. He stood by as if he were going to spring at Tom Curtis.

Madge's cheeks were burning. She was so angry that her throat felt dry and parched. "Don't pay any attention to him," she called indignantly. Tom Curtis hesitated.

"I don't fight when I have a woman guest on board the boat," he declared doggedly. "Once I run my boat in to the pier, you will answer for this."

"Never mind threatening me: I'm not afraid of you. You know you have got to land me where I say. What do you care about where you land? It is where I land that is important." Again the stranger made a rush for the tiller.

Tom sprang upon him. The two were evenly matched, and Madge held her breath as she watched them struggle. Brownie, Tom's setter dog, sprang for the stranger's leg, then retreated to one end of the boat howling with pain. The intruder had swung back his foot and dealt the dog a savage kick.

The rain had now begun to fall heavily, and the deck soon became slippery as glass. The two young men continued to struggle. Tom realized that he was endangering Madge's life, as well as his own, in this reckless battle on the deck of a small boat. He thought he now had the advantage. If he could only settle his hateful passenger with one swift blow all would he well. With this thought in mind he tore himself from the grasp of his antagonist, but he had forgotten the slippery deck. His foot shot out from under him, and he went down in a heap, falling heavily on one shoulder. The stranger sprang upon him, and now it was the ungrateful passenger who had the advantage and was mercilessly pushing him with both arms toward the edge of the boat. Slowly Tom gave way, inch by inch. He was conscious of a racking pain in his shoulder. He tried to raise his right arm; then a feeling of faintness swept over him, he reeled, and, before Madge could move to his help, Tom Curtis fell backward into the water.

CHAPTER XII

A BRAVE FIGHT

"Bring her to!" cried Madge imperiously, starting toward the stranger, who now stood by the tiller.
