Joke from 1888 newspaper

There were visitors at the Shinner school the other day and a class was put on exhibition. "Now" said the teacher "can you tell me anything about heat" A small boy held up his hand. "Well, sir" said the teacher "Heat expands; cold contracts" "Very good; no give an example" "In summer the days are long; in winter the days are short" Great applause by the visitors and the small boy took his seat.
