"Oh, my!" cried Bunny, and then, before Sue could stop him, her brother ran to the edge of the hill. He saw his toy engine and cars rolling over and over toward the lake at the bottom of the hill, and, without stopping a second, over the hill went Bunny Brown himself—slipping, sliding and falling down!
"Oh, Bunny! Come back! Come back!" cried Sue, very much excited.
But Bunny was rolling over and over down the hill after his train, and he could not answer.
CHAPTER VI
AFTER THE LOST COW
Bunny Brown was thinking of two things when he started to roll downhill. One was that his train might roll into the water and be spoiled, for his father had told him that there were bits of electrical machinery on the engine 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.
