"Oh, I know what it is!" he cried. "It's peanuts! The man is roasting peanuts and they whistles to tell him they're done. Don't you 'member, down at the corner by Daddy's office, home, there's a man an' he sells peanuts and they whistles." "Oh, yes!" said Margy. "I 'members! I likes peanuts, too!" "So do I!" said Mun Bun. The man with the gold rings in his ears was stopping in front of Aunt Jo's house now. He smiled at the children, while the steam from the hot peanut-roaster made a louder whistling sound, and the man yelled: "Hot peanuts, five cents a bag!" "Oh, I wish we had some!" sighed Mun Bun. "So do I," added his sister. "Have you five cents, Mun Bun?" "Nope! Has you five cents, Margy?" "No." Mun Bun thought for a few seconds while the smiling Italian man, with the whistling wagon, looked at the two little Bunkers hanging on Aunt Jo's gate. "Please go 'way!" said Mun Bun. "We hasn't got any five cents for your hot peanuts." "No gotta five cents?" asked the Italian. "No," and Mun Bun shook his head. "An' we like peanuts," added Margy. "If you've any left over you could give us some." "Hot peanuts--five a bag!" said the peddler in a sort of sing-song voice. "Please go 'way!" begged Mun Bun again. "They smells awful good, but we hasn't got any five centies!" "Maybe you go in th' house, li'l' boy, you get money," the Italian went on. Margy looked at Mun Bun and Mun Bun looked at Margy. "Oh, maybe we could!" exclaimed the little girl eagerly. "Let's go an' ask, Mun Bun!" "All right!" said he. "We will!" And they did. Into the room where Aunt Jo and Mother Bunker were sewing burst the two children, out of breath from their run up the gravel drive. "Oh, Mother!" cried Mun Bun. "He wants five cents." "An' he's got a whistlin' wagon!" added Margy. "An' they smell awful good!" went on her brother. "Come an' hear the whistle," begged the little girl. "My goodness me!" cried Aunt Jo. "What is this all about?" "It's hot peanuts--five a bag!" answered Mun Bun, in a sing-song voice almost like the Italian's. "But we haven't the five cents," added Margy. "An' we want some peanuts." "Well, I think you may have some," said Mrs. Bunker. "I'll come down to the whistling wagon with you and see about it." Margy and Mun Bun led her down to the front gate, where the peanut man, still smiling, was waiting. The hot oven on his wagon, in which he roasted the peanuts, was still whistling. Afterward Daddy Bunker told the children that the steam came out and made the whistling sound by puffing itself through a tin thing with holes in it, just as a boy blows his breath through the same kind of tin thing to make a whistle.
