_Eaux._--All the rivers, both navigable and floatable (admitting the passage of rafts), belonged to the King, although they flowed through the property of lords of the manor, and in spite of any title to the contrary. (See Ordinance of 1669.) If the lords of the manor levied any dues upon these rivers, it was those arising from the rights of fishing, the mills, ferry-boats, and bridge-tolls, &c., in virtue of concessions emanating only from the King. There were some lords of the manor who still arrogated to themselves the rights of jurisdiction and police upon these rivers; but this manifestly only arose from usurpation, or from concessions improperly acquired. The smaller rivers unquestionably belonged to the _Seigneurs_ through whose property they flowed. They possessed in them the same rights of property, of jurisdiction, and police, which the King possessed upon the navigable rivers. All _Seigneurs Hauts Justiciers_ were universally the lords of the non-navigable rivers running through their territory. They wanted no other legal title for the exercise of their claims than that which conferred the right of _haute justice_. There were some customs, such as the _Coutume du Berri_, that authorised private individuals to erect a mill upon the seignorial river passing through the lands they occupied, without the permission of the _Seigneur_. The _Coutume de Bretagne_ only granted this right to private personages who were noble. As a matter of general right, it is very certain that the _Seigneur Haut Justicier_ had alone the right of erecting mills throughout every part of his jurisdiction. No one was entitled to erect barriers for the protection of his property without the permission of the judges of the _Seigneur_. _Fontaines.--Puits.--Routoirs.--Étangs._--The rain-water that fell upon the high roads belonged exclusively to the _Seigneurs Hauts Justiciers_; they alone were enabled to dispose of it. The _Seigneur Haut Justicier_ possessed the right of constructing ponds in any part throughout his jurisdiction, and even upon lands in the possession of those who resided under it, upon the condition of paying them the price of the ground put under water. Private individuals were only able to make ponds upon their own soil; and, even for this, many _coutumes_ require that permission should be obtained of the _Seigneur_. The _coutumes_, however, thus requiring the acquiescence of the _Seigneur_, establish that it is to be given gratuitously.
