2 A usufruct may be created not only in land or buildings, but also in slaves, cattle, and other objects generally, except such as are actually consumed by being used, of which a genuine usufruct is impossible by both natural and civil law. Among them are wine, oil, grain, clothing, and perhaps we may also say coined money; for a sum of money is in a sense extinguished by changing hands, as it constantly does in simply being used. For convenience sake, however, the senate enacted that a usufruct could be created in such things, provided that due security be given to the heir. Thus if a usufruct of money be given by legacy, that money, on being delivered to the legatee, becomes his property, though he has to give security to the heir that he will repay an equivalent sum on his dying or undergoing a loss of status. And all things of this class, when delivered to the legatee, become his property, though they are first appraised, and the legatee then gives security that if he dies or undergoes a loss of status he will ay the value which was put upon them. Thus in point of fact the senate did not introduce a usufruct of such things, for that was beyond its power, but established a right analogous to usufruct by requiring security. 3 Usufruct determines by the death of the usufructuary, by his undergoing either of the greater kinds of loss of status, by its improper exercise, and by its nonexercise during the time fixed by law; all of which points are settled by our constitution. It is also extinguished when surrendered to the owner by the usufructuary (though transfer to a third person is inoperative); and again, conversely, by the fructuary becoming owner of the thing, this being called consolidation. Obviously, a usufruct of a house is extinguished by the house being burnt down, or falling through an earthquake or faulty construction; and in such case a usufruct of the site cannot be claimed. 4 When a usufruct determines, it reverts to and is reunited with the ownership; and from that moment he who before was but bare owner of the thing begins to have full power over it. TITLE V. OF USE AND HABITATION A bare use, or right of using a thing, is created in the same mode as a usufruct, and the modes in which it may determine are the same as those just described. 1 A use is a less right than a usufruct; for if a man has a bare use of an estate, he is deemed entitled to use the vegetables, fruit, flowers, hay, straw, and wood upon it only so far as his daily needs require: he may remain on the land only so long as he does not inconvenience its owner, or impede those who are engaged in its cultivation; but he cannot let or sell or give away his right to a third person, whereas a usufructuary may.
