The original map can be interacted with on the ArcGIS website

The colleges labeled with darker colored dots were established earliest, and those with lightest color dots, the latest (First: Harvard University, 1636; Last: Carleton College, 1866). The purple overlay shows existing rail road lines in the United States in 1850. Of the colleges that had been established by 1850 in the United States, almost all have a rail road line running directly through their town.
