"Of course he won't," said Margy. "He isn't a bossy-calf."
"Of course he won't," added Laddie. "Mother told us not to, and Mun Bun will mind mother."
"Shout for him!" commanded Russ, and raised his own voice to the very top note in calling Mun Bun's name.
The chorus of calls brought no response from Mun Bun. Only an old crow cawed in reply, and of course he knew nothing about Mun Bun or where he had gone.
Russ got off the rail again in his excitement, and down went the calf!
"Oh, you mustn't!" gasped Rose. "You'll drown him."
"But I guess we've got to find Mun Bun," said Vi.
Russ, however, had another idea. He was frightened because of the little boy's disappearance, but he did not want to lose the calf, having already partly saved him from the mud.
"You and Laddie, Vi, come here and help Rose hold down the rail," said Russ.
"But I must go look for Mun Bun, too!" cried Rose.
