This arrangement for visits to the congregations was supplemented in 1938 by the service of the regional servant in a new role. He covered a larger area, periodically spending a week with each of the brothers who were traveling in a zone (circuit) to visit the congregations. During his visit he served on the program of an assembly that was attended by all the congregations in that zone.b This arrangement was a great stimulus to the brothers and provided regular opportunity for baptism of new disciples.

From 1938 through 1941, regional servants, in a new role, regularly served local assemblies, where Witnesses from a limited area (a zone) met for a special program.
