MISCELLANEOUS BILLS. 365

The Commission may, of its own motion, investigate or make
inquiry in a manner to be determined by it, as to any act or
thing done or omitted to be done by any common carrier, rail-
road, street railroad, railroad corporation or street railroad
corporation, or other corporation, subject to its supervision,
and the Commission must make such inquiry in regard to any
act or thing done or omitted to be done by any such common
carrier or corporation in violation of any provision of law, or
in violation of any order of the Commission.

Complaints may be made to the Commission by any person
or corporation aggrieved, by petition or complaint in writing
setting forth anything or act done or omitted to be done by
any common carrier or corporation subject to its supervision,
in violation, or claimed to be in violation, of any provision of
law or of the terms and conditions of its franchise or charter,
or of any order of the Commission, or as being unfair, unrea-
sonable, unjustly discriminating or unduly preferential. Upon
the presentation of such a complaint the Commission shall
cause a copy thereof to be forwarded to the person or corpora-
tion complained of, accompanied by an order, directed to such
person or corporation, requiring that the matter jomplained of
to be satisfied, or that the charges be answered in writing within
a time to be specified by the Commission. If the person or
corporation complained of shall make reparation for any in-
jury alleged and shall cease to commit or to permit, the viola-
tion of law, franchise or order charged in the complaint, and
shall notify the Commission of that before the time allowed for
answer, the Commission need take no further action upon the
charge. If, however, the charges contained in such petition be
not thus satisfied, and it shall appear to the Commission that
there are reasonable grounds therefor, it shall investigate
such charges in such manner and by such means as it shall
deem proper, and take such action within its power as the
facts justify.

Whenever the Commission shall investigate any matter com-
plained of by any person or corporation aggrieved by any act
or omission of a common carrier or other corporation subject,
to the provisions of this Act under this section, it shall be its
duty to make and file an order either dismissing the petition
or, complaint or directing the common carrier complained of
to satisfy the cause of complaint in whole or to the extent
which the Commission may specify and require.

JUST AND REASONABLE RATES AND SAFE AND ADEQUATE SERVICE
To BE DETERMINED BY THE COMMISSION.

SEC. 23. And be it further enacted, That whenever the Com-
mission shall be of the opinion, after a hearing, upon its own
