But Bunny soon grew tired of making the train go around in a circle. He wanted it to run along on a straight track, as the real trains do, and, having plenty of straight lengths of track in his box, he soon set up more rails that stretched off in a straight line.
"Oh, you're gettin' awful near the edge of the hill that goes down to the lake," warned Sue, as she made believe to feed her Teddy bear some huckleberries.
"But I'm putting a curve at the end of the track so the engine and cars will turn back toward me," said Bunny. "Than I'll shut off the power before they can run off on the ground."
Bunny started his train the new way. At first the engine and the cars rolled slowly over the rails, for the ground was a little uphill. Then they came to a part that was downhill.
"Now see 'em go!" cried Bunny in delight.
"They're going awful fast!" cried Sue. "You'd better look out!"
"This is an express train," explained Bunny. "Express trains are very fast."
Indeed the toy locomotive did seem to be going very fast. It rocked and swayed on the tin rails, and it was soon near the end of the line where there was a curve.
And there is where the accident happened. The curve was so sharp, and the electric engine was going so fast, that, instead of turning around, it kept on straight, jumped over the rails and began to run down hill on the dirt and stone path that led to the lake.
"Oh!" gasped Sue.
