As Bunny and his sister had played this game more than the others, they were allowed to lay out the plans. Bunny showed the boys how the boards were to be put across the boxes to make shelves, and Sue took the girls down to the brook to gather little pebbles and the shells of fresh water mussels which were to be used for money, as there were going to be so many "customers" for the barn store that Mrs. Brown's buttons would not be enough to make change.
"What things are we going to sell?" asked Charlie, as he began pulling something from his pocket.
"Oh, we'll get stones, sand, gravel, some leaves, pieces of bark, twigs, and things like that," Bunny explained. "But what you got in your pocket, Charlie?"
"My wind-up auto. I thought maybe we could use it in the store."
"How?"
"Well, it could be like a cash register. You see," Charlie went on, "somebody's got to be the cashier just as in a big store. We'll have different clerks, and when anybody buys anything they must pay the money to whoever is clerk."
"Yes," agreed Bunny, who understood thus far.
"Then," went on Charlie, "the clerk must put the money the customer pays into my auto, and send it on a plank up to the cashier's desk. The cashier will make change and send it back in the auto."
"Oh, that'll be great!" cried Bunny. "And I guess you ought to be the cashier for thinking it up, Charlie."
"Well, maybe I ought, 'cause it's my auto," Charlie said. He had been hoping for this all along. "Now I'll make myself a place to be cashier," he went on, "and I'll fix up a long plank for the auto to run back and forth on. One winding will bring it up to me and back to the clerk."
