Cabinet card photograph showing a large multi-story wooden mill structure built on a substantial stone foundation directly over a stream or millrace. Three arched openings at the base allow water to pass beneath the building, indicating the structure functioned as part of a water-powered milling operation. The tall rectangular building features multiple rows of windows and a steep roof with a small rooftop platform or lookout.

Additional mill machinery and wooden structures are visible at the left edge of the image, likely associated with the waterworks that powered the operation. The foreground shows shallow water and debris along the streambed, reinforcing the industrial setting and the relationship of the building to the watercourse.

The mount reads “Cabinet Portrait – J. A. Salzman, Merrimac, Iowa.” While cabinet cards typically show portrait subjects, photographers occasionally produced views of local landmarks and industrial structures such as mills, bridges, and factories.
