When the portion to be divided from a district consists of more than three adjacent towns, the divided portion may either become a separate district or be combined with an existing district as provided in section 738 of this title. When the State Council has determined that it is administratively feasible and practicable for the divided portion to become a separate district and by resolution has declared such a change to be in effect, it shall appoint two supervisors for each of the new districts. The procedure outlined in section 738 shall then be followed in completing the organization of the two new districts and in apportioning the assets, rights, and properties of the divided district among the new districts. (Amended 1959, No. 329 (Adj. Sess.), § 11(c), eff. March 1, 1961.)
