"Very well," said the schoolmaster, for this, rather than teacher,
is the country name of the office. "Now, Ephraim, do you think you
can explain it?"

"I don't know, sir," said Ephraim, dubiously.

"Suppose you try. You may take the same sum."

Ephraim advanced to the board with reluctance, for he was not
ambitious, and had strong doubts about his competence for the task.

"Put down 625."

Ephraim did so.

"Now extract the square root. What do you do first?"

"Divide it into two figures each."

"Divide it into periods of two figures each, I suppose you mean.
Well, what will be the first period?"

"Sixty-two," answered Ephraim.

"And what will be the second?"

"I don't see but one other figure."

"Nor I. You have made a mistake. Harry, show to point it off."
