"No," replied Felix: "I'll sit up here, and see you do it."
"Oh! that's the kind of a surveyor you'll be," replied Johnny; "you'll survey from a distance: but this is ever so much more interesting. Come, Sue, you hold the measure for me, and I'll measure the width of the yard first. Stand back there, and keep the measure close to the fence; and when I say 'Come,' bring it to me."
As it was getting pretty dark, Felix could not see much except Johnny's and Sue's forms as they moved about. Having measured the width of the yard, Johnny measured the length.
"It is three times as long as it is broad," he announced.
"I could have told that without measuring," returned Felix scornfully. "Arithmetic isn't of any use at all."
"You had better come down before it gets any darker," said Johnny, "or you may fall."
"Fall! Oh, ho! I guess not! I ain't a baby."
"I'm going in now, to reckon this out," said Johnny. "Seventy-five feet wide, and two hundred and twenty-five feet long, or twenty-five yards wide, and seventy-five yards long. It will be easiest to find the square yards."
"How do you find the square yards," demanded Felix.
"Oh! I know that," remarked Sue; "just multiply the yards long by the yards wide: don't you, Prof.?"
