k, making a
little pond. And then, when the pond was full, the water ran over the
top of the mud wall, and down on the other side. That was why it was
called a "waterfall."

"Now I'll put some stones down first," Bunny explained to Sue. "You get
some pieces of grass, with the dirt on the roots, and put them on top of
the stones. That's good to hold the water back."

"Shall I get wood, too?" asked Sue.

"No. Wood will only float away on top of the water," Bunny said. "We
have to have something that will sink, like stones and dirt."

The two children were soon making the waterfall. They splashed about in
the mud and water, but they did not mind. For they had taken off their
shoes and stockings, though their mother had not said they could do so.

"But she wouldn't want us to go into the water with our shoes and
stockings on would she, Sue?" asked Bunny.

"No, I guess not."

"So we'll have to take them off."

That was all there was to do. The children rolled up their sleeves, for
they had to reach down in the mud to get the stones and clumps of grass
to make the waterfall.

Pretty soon Bunny and Sue had built such a high wall of stones, mud and
grass across the little brook, that no more water ran down the little
stream. The water had gathered into a sort of pond, that was getting
larger all the while, as it rose behind the stones.

"Oh, now it's running over!" cried Sue.

"Yes, now it's a waterfall!"

The water was trickling over the edge of the top of the wall. In a
moment it ran down in quite a stream on the other side.

"If I only had a water-wheel the water would make it go around," said
Bunny.

"Can't you make one?" Sue wanted to know. She was always anxious to see
something new and different.

"I guess water-wheels are hard to make," Bunny said. "But I'll ask
Bunker Blue when we go home."

Bunker Blue had also stayed on grandpa's farm. He helped with the work,
and he said he liked it almost as much as going out in boats, or helping
catch fish.

But as they did not have a water-wheel, and as Bunny could not make one
there, the children had what fun they could. They floated sticks, and
bits of bark from the trees, on the little pond that was made at the
waterfall, and they watched the tiny "boats," sucked over the edge of
the fall by the current. The fall was about a foot high, about as far as
from Bunny's knee down to his toes.

"If we had a real boat we could go for a ride on the pond," said S
