The Broken Mirror.
The painters have given the last finishing touches to the room they have been redecorating, but before leaving they cannot resist the temptation of a joke on whoever is sent to see that all is in order. Imagine the horror of the servant-girl when she sees a great crack, perhaps half a dozen, right across the big drawing-room mirror. Meanwhile, behind her back the workmen are smiling over her discomfiture. After having sufficiently chuckled over the success of their innocent joke they offer to repair the damage, and, not to keep their victim longer in suspense, one of them takes a wet cloth and passes it over the supposed crack in the glass. Lo, a miracle! The cracks disappear under the mere touch of the damp duster, and the glass is whole again. She can hardly believe her own eyes. And yet there is no witchcraft about the matter. If you are inclined to play a similar trick, you have only to trace, with a small piece of soap, on the mirror which is to appear broken, a few fine lines in imitation of cracks. Their reflection in the glass will give them depth, and make them seem as though they extended through the thickness of the glass, while a rub with a wet flannel will make all right again.
