"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."
Harry Walton did so.
"Now what do you do next?"
"Divide the first figure by three."
