QUOTE : In the early days of the country, before we had railroads, telegraphs and steamboats—in a word, rapid transit of any sort—the States were each almost a separate nationality. At that time the subject of slavery caused but little or no disturbance to the public mind. But the country grew, rapid transit was established, and trade and commerce between the States got to be so much greater than before, that the power of the National government became more felt and recognized and, therefore, had to be enlisted in the cause of this institution.
