Burt M. McConnell, Tales of the Air Mail Pilots (1925)

And no branch of the Post Office Department takes greater pride than the Air Mail Service in the motto from Herodotus that is carved above the portal of the New York Post Office:“Neither snow, nor rain, nor heat, nor gloom of night stays these couriers from the swift completion of their appointed rounds.” ”
