Macdonald had to attend a funeral to-day, and he asked me if I would take his classes for an hour. I gladly agreed.

"Give them a lesson on psychology," he said; "it will maybe improve their behaviour."

I went over to the school at two o'clock, and Mac introduced me, although I had already made friends with most of the children in the playground and the fields. Mac then went away and I sat down at his desk.

"We'll have a talk," I said, "just a little friendly talk between you and me. I want to hear your opinions on some things."

They looked at me with interest.

"Why," I said, "why do you sit quiet in school?"

Andrew Smith put up his hand.

"Please, sir, 'cause if we don't the mester gies us the strap."

"A very sound reason, too," I commented. "And now I want to ask you why you sometimes want to throw papers or slate-pencils about the room."

"Please, sir, we never do that," said little Jeannie Simpson.
