that would be spoiled if water touched them.

Then Bunny thought of himself rolling into the water, for the hill was
steep on this shore of the lake, and any one rolling down, if he were
not stopped before he reached the bottom, would be almost sure to go
into the lake.

"But I don't mind so much about myself," thought Bunny. "My clothes will
get wet, but I've got on an old suit and water won't hurt that. It won't
hurt me, either, for I get wet when I go in swimming, and I can swim now
if I have to. But my train can't swim, 'cause that's iron, and iron will
sink, daddy told me. So I've got to catch the train before it goes into
the lake."

The thought of this made Bunny try to roll over and over faster, so he
could win in the race down the hill between himself and the train. If he
could get hold of the train before it touched the water all would be
well, he hoped. He could toss the train to one side, out of harm's way,
even if he fell into the water himself.

"But can I get it?" thought Bunny, as he rolled over and over.

He could hear Sue calling to him at the top of the hill, on the very
edge of which he had made the curve of his track. He realized now that
it was too near the edge. What Sue was saying Bunny could not hear, but
he imagined she was begging him to stop rolling downhill and come back
to her.

"As if I could!" thought Bunny to himself. "This rolling downhill isn't
any fun. I didn't really mean to do it, but I couldn't help it. I wanted
to run or slide down. There are too many stones for rolling."

Indeed there were, for the slope of the hill down to the lake was not
of soft grass. Instead it was of gravel and stone and these were very
rough for a small boy to roll on. Still Bunny did not mind if he could
get his locomotive and train of cars.

He could see them just ahead of him, rolling over and over just as he
was doing. Of course there was no electricity in the toy locomotive now.
The current, as the electricity is called, was all in the rails, going
into them from the batteries, and from there it went into the motor or
the wheels, gears and other things inside the engine that made it roll
along.

"I guess it's rolling faster than I am," thought Bunny. "It will get to
the bottom first, and go in the water."

This seemed to be what would happen. For the engine and cars had started
ahead of Bunny, and, too, they were not so big as he. It took him some
time to turn over, for there was more of h
