using limestone quarried from the banks of the Rideau River, as well as wood cut locally and milled at the Long Island Sawmill. The mill's interior is highly ornamented; the partners, Dickinson and Currier, wished to make the Mill a model for industrial achievement and business entrepreneurship. Watson's Mill was powered by five turbines constructed in Joseph Currier's foundry. With a sixth turbine that was used to power the Bung Mill across the river. The Ottawa Citizen newspaper described Watson's Mill as "a castle in the air" on its opening day. Watson's Mill continues to run milling demonstrations on Sundays during the summer season. Whole wheat flour milled onsite is available for sale in the gift shop as well as fresh whole wheat bread made from Watson's Mill flour. Today, Watson's Mill still has much of the original machinery in working order. The following machinery is active in milling demonstrations: 3 of the 6 original turbines (others onsite but unused) 1 of the 4 original pairs of millstones (another on display); 5th turbine powered the rest of the machinery. Auger Bolter Feed grinder hopper and grain Elevators 6th powered the Bung Mill Turbines The turbines are the most important pieces of machinery as they supply power to all the other equipment in the mill. They are the originals, cast in 1859 in the Victoria Foundry in Ottawa. The larger turbines can generate 40-horse power and the smaller one makes 20-horse power. The turbines could operate all year, because the constant flow of water through the flume never froze. The first turbine drives the feed grinder and bolter, the third drives the elevators and auger, and the fifth drives the millstones and the seed cleaner. The other three are no longer in use. Hopper, Elevators and Garner Bin After the wheat is weighed, it is dumped into the receiving hopper. There is a small opening at the bottom, which is controlled by a lever. It allows the miller to control the amount of wheat that enters the system. This begins the automated milling process. From this point on, the grain and grist do not come into contact with human hands until the flour is ready to be bagged. Once poured through the hopper, the grain is conveyed to the second floor, via the conveyor elevator, and stored in a large storage bin called the garner bin. Millstones and Auger Millstones can
