IV. But to proceed to proofs derived from actions. A thing is understood to be abandoned, when it is cast away; except it be under particular circumstances, as throwing goods overboard in a storm to lighten a ship, where the owner is not supposed to have abandoned all intention of recovery, should it ever be in his power. Again, by giving up or cancelling a promissory note, a debt is deemed to be discharged. Paulus the Lawyer, says, a right to property may be renounced not only by words, but also by actions, or any other indication of the will. Thus, if an owner knowingly make a contract with any one who is in possession, treating him as if he were the rightful proprietor, he is naturally supposed to have relinquished his own pretensions. Nor is there any reason, why the same rule may not take place between sovereign princes, and independent states, as between individuals. In the same manner, a Lord by granting certain privileges to his Vassal, which he could not legally enjoy without a release from his former obligations, was supposed by such act to have given him his freedom. A power derived not from the civil law only, but from the law of nature, which allows every man to relinquish what is his own, and from a natural presumption that a person designed to do the act which he has given manifest proofs of his intention to do. In this sense, Ulpian may be rightly understood, where he says, that ACCEPTILATION or the verbal discharge of a debt is founded upon the law of nations. V. Even omissions, taking all proper circumstances into consideration, come under the cognizance of the law. Thus the person, who knowing of an act, and being present at the commission of it, passes it over in silence, seems to give his consent to it; this was admitted by the Mosaic Law. Unless indeed it can be shewn that the same person was hindered from speaking either by fear or some other pressing circumstance. Thus a thing is accounted as lost when all hope of recovering it is given up; as for instance, if a tame animal, which was in our possession, be seized and carried off by a wild beast. Goods too lost by shipwreck, Ulpian says, cease to be considered as our own, not immediately, but when they are lost beyond all possibility of being reclaimed, and when no proofs of the owner's intention to reclaim them can be discovered. Now the case is altered, if persons were sent to inquire after the lost goods, or property, and a reward was promised to the finder. But if a person knows his property to be in the possession of another, and allows it to remain so for a length of time, without asserting his claim, unless there appear sufficient reasons for his silence, he is construed to have entirely abandoned all pretensions to the same. And to the same purpose he has said elsewhere, that a house is looked upon to be abandoned on account of the long silence of the proprietor.
