When the time and place for a hearing is fixed by the board of directors under this article, and for any reason the hearing is not then and there held or regularly adjourned to a time and place fixed, the authority of the board shall not thereby be divested or lost, but it may thereafter fix a time and place for the hearing and cause notice thereof to be given by publication by at least one insertion in a newspaper published and of general circulation in the county within which the district is located and designated by the board. The publication shall be run at least five days before the date of the hearing, and thereupon the board of directors may act as in the first instance.
