This is a good summary of Blackford’s passage. I found it extremely fascinating that the railroads set up the varying times zones in the U.S. As you have stated, it is obvious how much bureaucratic and departmental managing changed the face of business, and it continues to modern times. If you have ever been around construction sites and companies, they follow a very similar structure, especially with communication. A message begins at the source, and works it’s way up the hierarchy ladder until an answer/solution is found. I find it helpful to connect history with modern society and my own experiences.
