It shall not be lawful for any licensed pilot to demand, ask or receive for the pilotage of any vessel, or for any other services for which compensation is fixed by law, a greater sum than is authorized by this act and the act to which this is a supplement. And it shall be the duty of the wardens of the port of Philadelphia, whenever it shall have been satisfactorily proven to them that any licensed pilot had demanded, asked or received, for the pilotage of any vessel, or his services on board any vessel, a greater sum than is authorized by this act, to deprive such pilot of his license for the term of one year from the time when proof thereof shall have been made to them.
