Herbert M. Herget, Relays of swift post-runners linked the Empire, Herbert M. Herget, 1938

Relays of swift post-runners linked the empire fresh fish from the sea for the inca's dinner, word of troop movement, of new campaigns — all sped through the andes by barefoot express, averaging seven miles an hour, day and night. Here a fresh courrier waits at his stone posthouse for the knotted-cord record for his three mile stint. Date: 1938.
