Narrative: The wooden piece is an arboiteau clapper or sluice door, part of the dykeing system used by the Acadians.
Upon settlement in Nova Scotia in 1605, Acadians recognized the potential of the rich, fertile soils boasted by their new land. Despite the abundance of fertile soil, one big problem stood in the way of using this land. It was completely covered, twice a day, in the salt concentrated waters of the Bay of Fundy.
Using the knowledge acquired from similar problems in Europe, Acadians introduced some modification to their construction methods and began building dykes to keep the powerful tides at bay.
Using soil, mounds of sod were created which ran along the tide line. Sods of salt grass were put on both sides of the dyke to prevent erosion of soil. A special culvert, termed aboiteau, was incorporated into the dykes at certain points. Aboiteaux ran perpendicular, underneath the dyke to allow fresh water to flow off fields but keep salt water out. Such a feat was achieved by placing a one-way valve, referred to as a clapper, within the aboiteau.
