"We will now proceed to the regular lessons," said Mr. Burbank, in conclusion. "First class in arithmetic will take their places."
The first class ranked as the highest class, and in it was Harry Walton.
"What was your lesson to-day?" asked the teacher.
"Square root," answered Harry.
"I will give you out a very simple sum to begin with. Now, attention all! Find the square root of 625. Whoever gets the answer first may hold up his hand."
The first to hold up his hand was Ephraim Higgins.
"Have you got the answer?" asked Mr. Burbank in some surprise. "Yes, sir."
"State it."
"Forty-five."
