A gentleman was walking one day in the east end of the city of Glasgow. The streets were so narrow, and the houses so high, that little direct sunshine ever reached the houses on one side. The gentleman noticed a ragged, barefooted boy trying, with a small piece of mirror, to catch the sun's rays and direct them to a certain spot on one of the houses opposite. He became interested in the boy's earnest efforts.

"What are you trying to do, laddie?" he asked.

"Do you see yon window up there?" the boy replied. "Well, my wee brother had an accident two years ago, and is always lying on his back in yon room, and it is on the wrong side to get the sunshine, so I always try to catch the light in this wee glass and shine it into his room."
