Detach any of the following maps, appropriate to the time of year,
hold it between you and a lantern out-of-doors, and you have an
exact miniature of the sky. Or, better, cut squares of suitable
sizes from the four sides of a box; put a map over each aperture;
provide for ventilation, and turn the box over a lamp or candle
out-of-doors. Use an opera glass to find the smaller stars, if
one is accessible.
