Reuss

Reuss, a tributary of the Aar in Switzerland, rises on the northern face of the St Gothard, flows northwards past Andermatt and Amsteg, between which places its bed lies at the bottom of a wild and narrow gorge, spanned by the Devil's Bridge and other wonders of Swiss roadmaking, and enters the southern end of the Lake of Lucerne. This it leaves again at its northern end, at the town of Lucerne, and, still going nearly due north, reaches the Aar near Windisch (Aargau). Its length is 90 miles; its basin, 1317 sq. m.
