"Why, multiply the length by the breadth in yards, to get the square yards in the garden."
"What next?"
"Why, then reduce an acre to square yards, so as to know how many square yards there are in an acre."
"I can do that," said Felix, looking slightly interested; "but I never could see what use there was in it, and I don't see now."
"Come and do it, then," said Johnny coaxingly.
Felix hopped to the table slowly, on one foot, and sat down in the chair Sue placed for him; while Johnny brought the other chair for his foot.
"How many square yards were there?" said Felix, taking the paper and pencil, and resting the paper on a book he took from the table.
"You do it all yourself," replied Johnny; "seventy yards long, you know, and twenty-five yards wide."
Presently Johnny stopped figuring.
"Have you got through?" asked Felix.
