"Oh!" exclaimed Sue. "We heard the darkies on the cotton plantation play the mouth organ and banjo and we saw 'em dance!" she went on.

"Well, I don't claim that my dog can dance as well as a plantation darky," laughed the switchman. "But Bruno does pretty well. I'll get my mouth organ."

Bruno barked and leaped about when he saw his master come out with the mouth organ, and no sooner had the first few notes been blown than the dog, without being told, stood up on his hind legs and pranced around. He almost kept time to the music, and for a dog, he danced very well.

"Oh, I wish we had a dog like that!" sighed Bunny, when the dancing animal, wagging his tail, came to Mr. Black to be petted after the switchman stopped playing the mouth organ.

"Maybe I can teach Nutty's cat to dance," Sue said.

"I'm afraid not," said Mr. Black. "It is very hard to teach cats to do tricks. I've tried more than once, but I never had any luck. But Bruno is one of the smartest dogs I ever saw."

The children thought so, too, and after Bruno had done a few more tricks, such as turning somersaults, and lying down and rolling over, Mrs. Black came to say she thought it time for Bunny and Sue to go to bed.

"I only have one spare room," said the switchman's wife. "That has a large bed in it big enough for both of you. Don't you want to go to sleep now?"

Bunny looked at Sue and Sue whispered something to her brother.

"What is it?" asked Mrs. Black, seeing that something was "in the wind," as she remarked afterward.
