Pictured here are at least three generations of grain elevators in Goderich, Ontario. I say "three" because this facility possesses three marine towers (all of them stationary), which are easily identifiable by the vertical "slats" out of which their respective elevating legs can be lowered. Moving from right to left, we see:

1) a marine tower that is integrated into the mid-section of a brick or iron-clad warehouse (a common design-feature in the 1870s and '80s);

2) a tower that stands at the far-end of another brick or iron-clad warehouse, over which a horizontal gallery or "cupola" has been built (common in the '80s and '90s); and

3) a tower that is integrated into an all-steel mainhouse (common in the 1900s).

Note that, at the far left of the picture, we see a grain-storage warehouse that is made out of reinforced concrete (note the cylinders, the only ones utilized at this facility). It is my educated guess that this facility was constructed in four stages between 1875 and 1915, and that the 500,000-bushel elevator built by John S. Metcalf in 1907, using steel to construct the rectangularly shaped grain tanks, is #3 (above).
