Haupt, United States Military Railway Department. Construction And Transportation. No. 77.

Haupt, Photographs Illustrative of Operations In Construction And Transportation, As Used To Facilitate The Movements Of The Armies Of The Rappahannock, Of Virginia, And Of The Potomac, Including Experiments Made To Determine The Most Practical and Expeditious Modes To Be Resorted To In The Construction, Destruction and Reconstruction Of Roads And Bridges. No. 77–For the transportation of troops, no flooring or decking is required, and the rafts are so steady that men may sit or stand at pleasure. No. 77 represents a raft of twenty-four boats, packed with sixty-four soldiers, with guns and knapsacks–a load which could be safely carried in moderately smooth weather; but so much time is lost in getting the men to pack, three to a boat, that it is better to limit to two only.
