In days before Television and Radio News, towns used to employ a Town Crier to patrol the streets at night and cry out in a loud voice the time and the status of the streets: "One O'clock, and all's well." His reassuring cry and the time must have helped the citizens rest.
I wonder what he called when all was NOT well? Perhaps, "Two O'clock. Storm brewing, creek rising."
At the old folks home we have replaced the town crier with lighted digital clocks to tell us the time and a care giver who peers in at us to make sure all is well.
My grandparents had a cuckoo clock to chirp the time hourly, and I have a talking watch that states the hours: "Beep. It is three o'clock, A.M."
Usually I sleep right through the announcments, and I suppose folks slept right through the shouts of the town crier.
I wonder why these customs prevail, even in this modern day.
