[time-nuts] Selling time to the railroad

[Howard Davidson]

The physics department at the little Liberal Arts college  I went to in 
Iowa, Grinnell college, used to sell time to the Rock Island Railroad. 
We had two excellent pendulum clocks that back when this was in action, 
were synchronized to zenith crossings of particular stars. This was a 
manual operation performed by undergraduates who were paid to be up at 
weird hours of the night. The time ticks from the clocks were 
transmitted to the Rock Island station in town electrically. I presume 
they distributed it by telegraph.
