THE RIVER SEINE.

The source of the Seine is to be found near the hamlet of Envergeraux,
and about two leagues and half from the village of Saint-Seine, in
Burgundy. After a course of more than 200 leagues from east to west, it
falls into the Ocean, between Havre and Honfleur[20].

The depth of the Seine at Rouen allows this town to be classed amongst
the principal ports of France. They calculate at from 2000 to 2500 the
number of vessels of all sizes, which annually come this port.

Rouen to Paris, by the Seine_. Rouen, 1839, in-18vo, with maps and

The Aubette has its source at Saint-Aubin, a small village near Rouen.
