"A button? How in the world could that get in there?" asked his mother. "Unless you boys dropped it in when you were carrying the cream."
Bert and the other boys quickly looked at their coats. There were no buttons missing.
"An' it suah wasn't in when de cream come heah," said Dinah. "I knows, fo I took off de kiver an' looked in t' see how hard it were froze. Dat button got in since!"
"Yes, and I think I know how, too!" exclaimed Bert.
"How?" asked Freddie.
"It was dropped in by whoever took the freezer. They must have been eating the cream right out of the can, and maybe they dropped the button in. I'll save it."
"What for?" asked Nan, wonderingly.
"I may be able to find out by it, who took the freezer," went on Bert. "I'm going to look at the coats of all the fellows in school next week, and if I find one with the button like this missing, I'll know what to think."
"Be careful not to accuse anyone wrongly," cautioned his mother.
