"No, the sun is shining," said the twins' mother.
"But I'm sure that is thunder," went on Mrs. Morris.
There was a rumbling sound down the road, and there seemed to be some excitement there, for a number of children who had started toward the ice cream pavilion turned back.
"I wonder what it is," mused Mrs. Bobbsey. "I hope no 'almost' accidents are going to happen."
"I'll go see what it is," offered Bert.
He ran down the road, was gone a little while, and came back, his eyes shining with eagerness.
"Oh, it's a big merry-go-round!" he cried.
"A merry-go-round?" repeated his mother, busy at the ice cream.
"Yes, a man has a big merry-go-round in pieces on three or four big wagons," Bert reported. "Something's the matter with the engine—it runs by a steam engine, and something's the matter!"
"Bert, go call your father," said Mrs. Bobbsey, for her husband had gone to the far side of the grove to get another ice cream tub from the truck on which they were brought to the picnic. "We don't want any strange men setting up a merry-go-round here. Call your father!"
