[Blanket boats]

View of many blanket boats lashed together to create a raft floating on the Potomac River. Logs run across the top of the raft for support as a group of men stand in the boats and the water beside it to pose for the camera. Several of the men hold on to a large wooden beam at the center of the raft. Individual blanket boats rest along the riverbank, where sailing ships in the process of construction can be seen over a wooden fence.
