The faint vertical lines of the corrugated tin siding, softly bisected by horizontal lines where the sheets of metal are joined, establish a vertical thrust in this composition. The bold diagonal lines of the roofs intersect the anonymous-looking structure in dynamic bursts, while the three dark forms of windows and pipe balance the graphic tone of the image. A fine layer of white dust coats the visible surfaces, presumably from the smokestacks spewing a white cloud overhead.
