  (ii) shall have the same powers of collecting such octroi, terminal tax or toll in the aggregate area and the provisions of any enactment in force relating to the levy of such octroi, terminal tax or toll by it shall apply in the same manner as if the aggregate area were comprised within the area ordinarily subject to its control;
  (b) the total of the collection of such octroi, tax or toll made in the aggregate area and the costs thereby incurred shall be divided between the cantonment fund and the fund subject to the control of such other local authority, in such proportion, as may have been determined by the agreement.
