Now all this while Jimmie and Lulu were swimming nearer and nearer to the
waterfall. They could hear the water splashing on the rocks below, and
they liked to listen to it.

"We had better stop," called Lulu, after a while.

"No, I'm going closer," declared Jimmie. "There is no danger; come on!"

But just then Lulu felt something pulling her down toward where the big
wheel went around and around, and she got frightened. Then she swam just
as hard as she could toward shore, and called to her brother: "Jimmie,
don't go any closer! Come back!"

But Jimmie was a boy duck, and wanted to be brave, so he answered: "I'm
going just a little bit closer."

Now Lulu had a very hard time, indeed, getting to shore, as the current
was so strong, but she finally managed it. Jimmie, however, kept on
swimming nearer and nearer to the falls. Then, all at once, before you
could stick a pin in a cushion, what should take place but that the little
boy duck felt himself being pulled along by the rushing water, just as the
soap floats along when you pull the plug out of the bathtub. Oh, how fast
the water swept him along! Jimmie splashed and paddled with all his might,
and tried to swim ashore, where Lulu was anxiously watching him, but he
couldn't seem to move. There he was, being carried along to the edge of
the falls, with the cruel, sharp stones below, and the big millwheel going
around and around. Then Jimmie knew he was in great danger, and he cried
out: "Help! Help! Help!" three times, as loudly as he could call.
