run in a new one, the old channel belongs to the landowners
on either side of it in proportion to the extent of their riparian
interest, while the new one acquires the same legal character
as the river itself, and becomes public. But if after a while
the river returns to its old channel, the new channel again
becomes the property of those who possess the land along
its banks. 24 It is otherwise if one's land is wholly flooded,
for a flood does not permanently alter the nature of the land,
and consequently if the water goes back the soil clearly be-
longs to its previous owner.

25 When a man makes a new object out of materials belong-
ing to another, the question usually arises, to which of them, by
natural reason, does this new object belong -- to the man who
made it, or to the owner of the materials? For instance, one
man may make wine, or oil, or corn, out of another man's
grapes, olives, or sheaves; or a vessel out of his gold, silver,
or bronze; or mead of his wine and honey; or a plaster or
eyesalve out of his drugs; or cloth out of his wool; or a ship,
a chest, or a chair out of his timber. After many controversies
between the Sabinians and Proculians, the law has now been
settled as follows, in accordance with the view of those who
followed a middle course between the opinions of the two
schools. If the new object can be reduced to the materials
out of which it was made, it belongs to the owner of the
materials; if not, it belongs to the person who made it. For
instance, a vessel can be melted down, and so reduced to
the rude material -- bronze, silver, or gold -- of which it is
made: but it is impossible to reconvert wine into grapes, oil
into olives, or corn into sheaves, or even mead into the wine
