Charcoal sketch, with touches of watercolor, on paper. This landscape shows a flat expanse with a river in the background. At the left are men working, a locomotive, and a structure with a smokestack and another tall projectile. On the opposite side of the river, across the bridge, these same structures are repeated. In the foreground are several large, uncut lumber logs with men in between them. The catalog card for this drawing indicates that the men are troops engaged in erecting buildings.
