But if objections in writing are filed either to the proposed improvement or to the proposed method of paying the costs thereof, the commissioners shall proceed to hear and consider the same and may, thereupon, order that such proposed improvement be abandoned for the time being or may direct such improvement to be constructed and the order of the commissioners in that regard shall be final and conclusive on all parties interested: PROVIDED, HOWEVER, That no such proceeding shall be abandoned unless the owners of at least twenty-five percent of the acreage within said district shall have at or prior to said hearing, filed protests against the same. But nothing contained in *this act shall be held to forbid the commissioners in their discretion overruling all protests and directing the construction of such improvement.

Commissioners shall likewise hear and consider all objections that may be filed to the proposed method of paying the cost of such improvement.
