At last the yard was raked clean. They had taken to the garden twenty-nine loads. They had worked nearly all day.
At supper father said, "You are good workmen, chicks. Our yard looks very clean. It is ready for winter.
"You piled the leaves carefully in the garden, too. Now, how much do I owe you?"
"We took twenty-nine loads, father," said Polly. "I wish there had been one more to make thirty."
"Why do you wish that, Polly?"
"Because three goes in thirty better than in twenty-nine."
"Well," said father, "we will call it thirty loads, Polly. I saw you packing the leaves into the basket very hard.
"You are honest workmen to give me such good measure. Now, Polly, three goes in thirty how many times?"
"Ten times, father. So you owe us ten cents. We shall each have five cents."
"Very good, Polly. Here is your money. I have a surprise for you. Put on your coats and come to the garden. Mother will come, too."
