Here advancemen were using the government postal system for distribution; there, making arrangements for private delivery; elsewhere, setting up booths. Earth had been scouted very thoroughly by four prior Intelligence expeditions. It was an inconceivably complex network of planning, possible only through extreme specialization in an organization made frictionless by obedience.
