Within ten days after the adoption by the town board of any resolution which is subject to a permissive referendum as above defined, the town clerk, in the same manner as provided for notice of a special election, shall post and publish a notice which shall set forth the date of the adoption of the resolution and contain an abstract of such act or resolution concisely stating the purpose and effect thereof. The notice shall specify that such resolution was adopted subject to a permissive referendum.
