Neatly as the boy Pretty ever skimmed a hurdle in a hurdle-race, the boat skimmed the gulf of water. The ice bent and cracked treacherously, and the water flew up in little jets where it broke; but Greased Lightning was off and away before there was ever a chance to engulf her. And then the heart of the Twins could beat again.

The boat was just well over the crack when she struck a patch of rough ice and yawed suddenly. There was a severe wrench. B.J. and Reddy were prepared for it; but Heady, before he knew what was the matter, had slid off the boat on to the ice and on a long tangent into the crack they had just passed.

He let out a yell, I can tell you, and clung to the edge of the brittle ice with desperate hands.

He thought he had been cold before; but as he clung there now in the bitter water, and watched B.J. trying to bring the obstinate boat about and come alongside, he thought that the passengers on the ice-boat were warm as in any Turkish bath.

After what seemed to him at least a century of foolish zigzagging, B.J. finally got the boat somewhere near the miserable Heady, brought the Greased Lightning to a standstill, and threw the dripping Twin the sheet-rope. Then he hauled him out upon the strong ice.

B.J. begged Heady to get aboard and resume the journey, or at least ride back home; but Heady vowed he would never even look at an ice-boat again, and could not be dissuaded from starting off at a dog-trot across the lake toward home.

Reddy wanted to get out and follow him; but B.J. insisted that he could not sail the boat without some ballast, and before Reddy could step out upon the ice B.J. had flung the sail into the wind again, and was off with his kidnapped prisoner. Reddy looked disconsolately after the wretched Heady plowing through the slush homeward until his twin brother disappeared in the distance. Then he began to implore B.J. to put back to Lakerim.

Finally he began to threaten him with physical force if he did not.

B.J. fairly giggled at the thought of at last seeing one of those mutinies he had read so much about. But he contented himself with having a great deal to say about tacking on this leg and on that, and about how many points he could sail into the wind, and a lot of other gibberish that kept Reddy guessing, until the boat had gone far up the lake.

At last, to Reddy's infinite delight, B.J. announced that he was going to turn round and tack home. As they came about they gave the wind full sweep. The sail filled with a roar, and the boat leaped away like an athlete at a pistol-shot.
