Photo 3: Pillsbury Mill Complex.

Photo 3 shows the Pillsbury complex. The Pillsbury A Mill on the left was built in 1881 at a cost of nearly half a million dollars. The large cylindrical buildings on the far right of the complex are reinforced concrete grain elevators. Each cylinder is a separate storage unit, holding thousands of bushels of wheat. Reinforced concrete provided cheap and efficient storage and some protection against the constant danger of explosions from spontaneous combustion of the wheat.

Concrete grain storage elevators were developed in Minneapolis by the Peavey Company. Their first elevator is still standing just west of Minneapolis.
