Any of you who happen to live in a house which has, like many old
houses, a narrow side-light on either side of its front-door, and a
row of panes across the top, can make a pretty effect by preparing a
series of these transparencies to fit the door-glasses, and fastening
them on by driving a stout tack into the sashes so as to support
the four corners of each pane. The transparencies could be prepared
secretly and put into place overnight, or on Christmas morning, before
any one is up, so as to give mother a pleasant surprise as she comes
downstairs.
