FREDERICKSBURG, a city of Spottsylvania county, Virginia, U.S.A., on the Rappahannock river, at the head of tide-water navigation, about 60 m. N. of Richmond and about 55 m. S.S.W. of Washington. Pop. (1890) 4528; (1900) 5068 (1621 negroes); (1910) 5874. It is served by the Potomac, Fredericksburg & Piedmont, and the Richmond, Fredericksburg & Potomac railways, and by several coasting steamship lines. The city is built on a series of terraces between the river and hills of considerable height. The river is here spanned by iron bridges, and just above the city is a dam 900 ft. long and 18 ft. high. By means of this dam and a canal good water-power is furnished, and the city's manufactures include flour, leather, shoes, woollens, silks, wagons, agricultural implements and excelsior (fine wood-shavings for packing or stuffing). The water-works, gas and electric-lighting plants are owned and operated by the municipality. At Fredericksburg are Fredericksburg College (founded in 1893; co-educational), which includes the Kenmore school for girls and the Saunders memorial school for boys (both preparatory); a Confederate and a National cemetery (the latter on Marye's Heights), a monument (erected in 1906) to General Hugh Mercer (c. 1720-1777), whose home for several years was here and who fell in the battle of Princeton; and a monument to the memory of Washington's mother, who died here in 1789 and whose home is still standing. Other buildings of interest are the old Rising Sun Hotel, a popular resort during Washington's time, and "Kenmore," the home of Colonel Fielding Lewis, who married a sister of Washington. The city was named in honour of Frederick, father of George III., and was incorporated in 1727, long after its first settlement; in 1871 it was re-chartered by act of the General Assembly of Virginia.
