The council of any county may, for the purpose of assisting the council of any rural district within the county in the performance of their duties under this Part of this Act, agree with the district council for the exercise by the county council of all or any of the powers of the district council under this Part of this Act.

An agreement made under this section may contain such provisions with regard to the expenses to be incurred by the county council, including the raising of loans to meet those expenses, and with regard to the vesting in the district council of any houses built by the county council under the agreement and such other incidental or consequential provisions as the councils think proper.
