Section 67. Hearing

On the day specified in the order, and before any other
  proceedings  are taken in the matter, the petitioner must present to the
  court, and file with the clerk, proof, to the satisfaction of the court,
  that the order has been published and served, as prescribed in the  last
  section;  and  thereupon,  on the same day, or upon the day to which the
  hearing is adjourned, the court must hear the allegations and proofs  of
  the  parties appearing. Proof of personal service of a copy of the order
  upon any person, must be made, in like manner as proof of  the  personal
  service of a summons, in an action brought in the supreme court.
