Two Scouts set off in a given direction with a lighted bull's-eye lantern. After two minutes have passed the patrol or troop starts in pursuit. The lantern bearer must show his light at least every mute, concealing it for the rest of the time. The two Scouts take turns in carrying the light, and so may relieve each other in difficulties, but either may be captured. The Scout without the light can often mingle with the pursuers without being recognized and relieve his friend when he is being hard pressed. They should arrange certain calls or signals between themselves.
