Photograph of two men standing on top of a large model of waterways, ca.1925. At center, two men dressed in formal attire crouch on rocky banks near the water's edge. The man on the left holds a small instrument in his left hand, while the man on the right watches. Behind the men, numerous ridges can be seen in the large model of a waterways system. On the outside of the model to the left, Two steel valves are visible. Behind the valves, a large wall with a door lies adjacent to a barred fence. In the background to the right, a large metallic crane arm is visibly angled above the waterways model. A crank can be seen above the tilted arm, and various ropes are also visible. In the extreme background, lines of palm trees and other vegetation are visible. In the extreme foreground, a portion of the wall of the model can be seen.
