I need only to call attention to the reasons why prescription was introduced.
"Prescription," says Dunod, "seems repugnant to natural equity, which permits no one either to deprive another of his possessions without his knowledge and consent, or to enrich himself at another's expense.

But as it might often happen, in the absence of prescription, that one who had honestly earned would be ousted after long possession; and even that he who had received a thing from its rightful owner, or who had been legitimately relieved from all obligations, would, on losing his title, be liable to be dispossessed or subjected again,--the public welfare demanded that a term should be fixed, after the expiration of which no one should be allowed to disturb actual possessors, or reassert rights too long neglected....

The civil law, in regulating prescription, has aimed, then, only to perfect natural law, and to supplement the law of nations; and as it is founded on the public good, which should always be considered before individual welfare,--_bono publico usucapio introducta est_,--it should be regarded with favor, provided the conditions required by the law are fulfilled." Toullier, in his "Civil Law," says: "In order that the question of proprietorship may not remain too long unsettled, and thereby injure the public welfare, disturbing the peace of families and the stability of social transactions, the law has fixed a time when all claims shall be cancelled, and possession shall regain its ancient prerogative through its transformation into property." Cassiodorus said of property, that it was the only safe harbor in which to seek shelter from the tempests of chicanery and the gales of avarice--_Hic unus inter humanas pro cellas portus, quem si homines fervida voluntate praeterierint; in undosis semper jurgiis errabunt_.
Thus, in the opinion of the authors, prescription is a means of preserving public order; a restoration in certain cases of the original mode of acquiring property; a fiction of the civil law which derives all its force from the necessity of settling differences which otherwise would never end.

For, as Grotius says, time has no power to produce effects; all things happen in time, but nothing is done by time.
Prescription, or the right of acquisition through the lapse of time, is, therefore, a fiction of the law, conventionally adopted.
But all property necessarily originated in prescription, or, as the Latins say, in _usucapion;_ that is, in continued possession.
I ask, then, in the first place, how possession can become property by the lapse of time?
Continue possession as long as you wish, continue it for years and for centuries, you never can give duration--which of itself creates nothing, changes nothing, modifies nothing--the power to change the usufructuary into a proprietor.

Let the civil law secure against chance-comers the honest possessor who has held his position for many years,--that only confirms a right already respected; and prescription, applied in this way, simply means that possession which has continued for twenty, thirty, or a hundred years shall be retained by the occupant.
