“Let’s charge on them!” cried Sully, angrily. “Come on—everybody take all the snowballs he can carry.”

The seven loaded up with ammunition at once, and they sallied forth. But, to their dismay, Jack and Andy Bascoe had just arrived on the scene, followed up by Pickles Johnsing, the colored youth. These three were not slow to take in the situation, and they sailed in vigorously.

“Dis am most lubly sport!” cried Pickles. “How yo’ like dat, Sully? Ki! hi! Ain’t dat jess elegant, Dixon? An’ heah’s one fo’ you, Len Spencer, fo’ callin’ me a coon!”

And Pickles rushed to the front, followed by Andy and Jack, and compelling Sully and his crowd to retreat in spite of themselves. Aided by Boxy and Harry, they fought so vigorously that inside of ten minutes the bully and his chums were put completely to rout.

Sully and Dixon, and also Len Spencer, Pickles’ particular enemy, were greatly enraged over the way they had been used. They threatened vengeance on the members of the Zero Club. How they carried out their threat will be seen later on.

CHAPTER VI.
LAST RIDE ON THE BUSTER.

By Saturday noon the iceboat was finished. It was nearly thirty feet long, and boasted of a mainsail only. It was by no means a handsome craft, and the boys did not doubt but what there were many crafts on the river that could outspeed her.

“But she’ll be safe and sure,” remarked Jack, “and that is what we want.”

“We must christen her before we make a trial trip this afternoon,” said Andy. “We have suggested a hundred names, and not chosen any.”

“Let us put each name on a slip of paper, and put all the slips in a hat,” suggested Boxy. “Then Harry draw one, and that shall be the name.”
