Community of interest. This term means joint ownership or joint control for the purpose of
maintaining harmonious relations.  When, for instance, one set of capitalists in control of one
railroad acquire an interest in a competing railroad with representation in its board of directors and
the set of capitalists in control of this second railroad acquire an interest in the other railroad with
representation in its board of directors, with the object of mutual benefit, a community of interest is
established. Also, when two competing railroads together acquire control of a third line connecting
with both a community of interest is established if the object be mutual benefit.
