[ULPIANUS libro sexto opinionum. ] §10.1.8.prSi irruptione fluminis fines agri confudit inundatio ideoque usurpandi quibusdam loca, in quibus ius non habent, occasionem praestat, praeses prouinciae alieno eos abstinere et domino suum restitui terminosque per mensorem declarari iubet. §10.1.8.1Ad officium de finibus cognoscentis pertinet mensores mittere et per eos dirimere ipsam finium quaestionem ut aequum est, si ita res exigit, oculisque suis subiectis locis.
[ULPIANUS, Book VI of Opinions.]\n\nIf a flood, by the breaking of a river, has confused the boundaries of a field and thereby affords to certain persons an opportunity of usurping places in which they have no right, the governor of the province orders them to abstain from what belongs to another, and his own to be restored to the owner, and the boundaries to be declared by a measurer.\n\nIt belongs to the duty of the judge who takes cognizance of boundaries to send measurers, and through them to settle the question of boundaries itself as is equitable, if the circumstances so require, after having inspected the places with his own eyes.
