small jewel or treasure that can be carried in one hand.
Define the play area depending on number of scouts. A 1/2 football field size for 30 scouts is about right.
Divide into two teams - the Smugglers and the Coast Guard.
The jewel is given to one member of the Smugglers. The Smugglers go to one end of the play area while the Coast Guard go to the other.
The smugglers can move the jewel from scout to scout as often as they like. The jewel must only be held in a hand, not concealed any other way.
The Coast Guard chase the Smugglers trying to tag them. When a smuggler is tagged, he must immediately stop and show both open hands. He must then sit and wait for the round to end. When the smuggler with the jewel is tagged, a new round is started with teams switching sides.
The leader can time each round to determine which Coast Guard team recovers the jewel fastest.
