"Horses run out when Trouble open gate," was the only reply Baby William made.

"Yes, I know," went on his mother. "But it was wrong! You must never again open any gates on Uncle Frank's ranch. Just think—the horses might have stepped on you or kicked you!"

"We didn't see him near the gate or we'd have stopped him," put in Teddy.

"That's true," added Janet. "The first we saw was the ponies going out, and then we saw Trouble behind the gate."

"He didn't mean to be bad," said his mother, as she carried him back to the house, "but he has made a lot of work. I'll have to punish him by not letting him out to play for an hour or so. Then he'll remember not to open gates again, whether he thinks he is helping horses or not."

And, though Trouble cried very hard, he was kept in the house. For, as his mother had said, he must have something to make him remember not to do such a thing again.

Meanwhile Uncle Frank and the cowboys were busy rounding up the runaway ponies. The little horses, tired of being cooped up in the corral, raced about, kicking up their heels and glad to be out on the prairie again. But the cowboys knew how to handle them.

Around and around the drove of half-wild ponies rode the yelling and shouting men, firing off many blank cartridges to scare the little animals back into the corral.

Some of the ponies, frightened by the noise, did turn back. They ran up to the corral gate, which was still open, and sniffed at the fence. They may have said to themselves:

"We don't like it, being shut up in there, but maybe well have to go back in, for we don't like being shouted at, and we don't like the bang-bang noises like thunder."
