The third floor has a complete grain system of its own separate from the main system on the fourth and fifth floors. There is a grain elevator shown in the left of the vertical picture that brings grain from the 2nd street Mill entrance. There are two cyclones and a shaker screen. There is also the Niagara Receiving Separator shown in the horizontal picture and at the right in the vertical picture. Many of the belts are still with the third floor system. What I find wonderful is all the beautiful old wood.
