"I'm hungry, aren't you?" said Don, taking the lunch from his pockets.
"Yes; let's have lunch now, and play river-men after," returned Dot.
As they sat munching the lunch the motion of the wavelets under the raft, dancing it up and down, made them laugh.
The ice-floe stuck close to them after Don jumped from it, and they never noticed that the floe and raft were slowly floating out from shore.
A sudden jar of the raft against another huge ice-floe that came down stream made them take notice of their greater distance from shore.
"Gee! Dot, we have floated out more'n ten feet from the bank!" said Don, looking about doubtfully.
"So we have! We'd better pole back again," said Dot.
Without another word, both children tried to pole back, but they were working against the current that had begun to take hold of the ice-floe and raft.
The ice-floe was so deep down in the water that the current that ran underneath drew it along. But the raft being on the surface was not so easily carried. Don thought for a few seconds.
"Dot, if we try to push that floe off we won't be dragged along with it. She's doin' all the mischief!"
