A river can have several names, one for its source, another for its
middle part and a third for its mouth. It is even probable that all
rivers once had more than one name and that only after their unity had
been recognized one of the names took precedence over the others. lt is
an established principle among modern etymologists that most ob- jects
owe their name to the way they can be used by man. Perhaps this is also
the case with proper names. If this principle is applied to river names
the etymologist has to deal above all with the river as a source of
food. The Germanie tribes and their neighbours usually caught the fish
by some sort of fence or wattle which they put across the river. There
are indeed obvious or at least recognizable relations between the name
of a river and fences and wattles of all description: e. g. Wern,
Varenne, Veken, Lahn, Main, Themse. Resurne Un fleuve peut avoir
plusieurs noms. Les riverains ne s'interessent pas au fleuve tout
