Title. Title to property does not pass from one to another unless there is a mutual agreement to
that effect.  If an agent has goods in his possession the title is still in the principal, although the
agent may have advanced a larger or smaller proportion of their value. If he is not an agent but
has simply advanced money on the security of the goods he has a lien upon them for his advance,
but he does not own them. In the absence of an agreement an agent who has made an advance
upon goods has a lien upon them to that extent. A creditor of the owner may take the goods and
sell them subject to his lien.
