Improvement in Means of Travel%.--We have now considered two of the results of the rush of population from the seaboard to the Mississippi valley; namely, the admission of five new Western states into the Union, and the struggle over the extension of slavery, which resulted in the Missouri Compromise. But there was a third result,--the actual construction of highways of transportation connecting the East with the West. Along the seaboard, during the five years which followed the war, great improvements were made in the means of travel. The steamboat had come into general use, and, thanks to this and to good roads and bridges, people could travel from Philadelphia to New York between sunrise and sunset on a summer day, and from New York to Boston in forty-eight hours. The journey from Boston to Washington was now finished in four days and six hours, and from New York to Quebec in eight days. [Illustration: Bordentown, NJ.[1]] [Footnote 1: From an old engraving.
