“ The passage of an express rider was always an event of prime interest. These men were their only links with the world. Often if they met them on the way they would not check the speed of the ponies, but pass on with a wave of the hand and a shout of 'All's well,' or 'Redskins about; keep well together.' It was only when a rider happened to reach one of the pony stations, often forty or fifty miles apart, while the caravan was there, that they could have a talk and learn what news there was to be told of the state of the country ahead. ”
