The old weather forecaster
When I was young, it was common to see barometers or barographs in people’s houses. They helped people forecast the weather, by measuring changes in atmospheric pressure – before the advent of regular TV weather shows, radar and computerised weather models.
This photo shows the ink bottle of my barograph. The ink is for the pen that draws the pressure line on the graph-paper, as a wind-up clock spins the graph-paper. You can see the silhouette of the pen in the back ground – and lines moving up, indicating higher pressure.
Today, it’s very unusual to see barographs in houses around here.
