"PER bushel, then!"

"Per bush-el. That's seven 'undered bushels of wheat at six shillin's per
bushel. An' y' wants ter know, Dad--?"

"In money, Dad, or--er----?"

Joe cleared his throat. We listened.

"Nine thousan' poun'."

Dave laughed loud. Dad said, "Pshaw!" and turned his face to the wall.
Joe looked at the slate again.

"Oh! I see," he said, "I did n't divide by twelve t' bring t' pounds,"
and laughed himself.
