newspapers, five academies with 256 students, and seven schools with 165 scholars. The population in that year was 3,974. Ten years previous it had been 3,308, divided as follows: whites, 1,797; slaves, 1,124; free blacks, 387. [Sidenote: _The City Limits Are Set_] From 1840 until the middle fifties, prosperity was continued. The canal was completed and had brought about an increased business at a lower cost. A railroad was in operation from Richmond through Fredericksburg to Aquia Creek, and steamboats had to some extent taken the place of sailing vessels as a means of water transportation, meaning quicker trips with greater burdens. In 1851 the legislature passed an act empowering the town to extend its limits, which was done according to a survey made by William Slaughter, and though that was more than seventy years ago, and though the population has since more than doubled, overflowing the limits and encroaching on the adjoining county, the limits have not again been enlarged. In 1855 Fredericksburg's trade had ceased to grow at a rate equal to its average yearly increase for the previous twenty years, a condition for which the business men of that day were not altogether responsible, but which rather was brought about by the new commercial era the country and world was just entering--the era of railroad transportation, which quickly and cheaply, in comparison to past charges, carried the staples of the farm to the ports of the sea where waiting vessels stood ready to spread their sable sails on voyages to foreign markets. This era created the importance of the seaport and spelled the doom, as important shipping points, of the tidewater cities--those which had been located at the point where mountain torrent and still water meet in order to get both the advantage of power production and trade routes.
