Baton

Chambers's Encyclopaedia, Volume 1: A to Beaufort, p. 796

Baton is the name of a short staff, presented by the sovereign to each field-marshal, as the symbol of authority. It is also the name of the long staff carried by the drum-major of an infantry regiment. Baton is also the name of the policeman's truncheon, and of the rod wielded by the conductor of an orchestra. (The French baton originally meant simply a stick.)
