The Scoutmaster's Benediction
For your closing, you may want to borrow this traditional Boy Scout closing, which has an Indian flavor.
The boys stand at attention, with their right hands in the "un-uniformed salute" position, that is, with the elbow bent and the right arm straight across the chest, the right hand over the heart folded in the Cub Scout salute. As they repeat the Benediction, they slowly move their right hands horizontally out in a semi-circle until the lower arm is pointing outward (keeping the elbow at their side), then move it back to the original position. Together, they repeat "May they great Master of all Scouts watch over you until we meet again."
