"How did you get it?"

Ephraim scratched his head, and looked confused. The fact was, he was entirely ignorant of the method of extracting the square root, but had slyly looked at the slate of his neighbor, Harry Walton, and mistaken the 25 for 45, and hurriedly announced the answer, in the hope of obtaining credit for the same.

"How did you get it?" asked the teacher again.

Ephraim looked foolish.

"Bring me your slate."

Ephraim reluctantly left his place, and went up to Mr. Burbank.

"What have we here?" said the teacher. "Why, you have got down the 625, and nothing else, except 45. Where did you get that answer?"

"I guessed at it," answered Ephraim, hard pressed for an answer, and not liking to confess the truth—namely, that he had copied from Harry Walton.

"So I supposed. The next time you'd better guess a little nearer right, or else give up guessing altogether. Harry Walton, I see your hand up. What is your answer?"

"Twenty-five, sir."
