Yesterday we showed a picture of balloon Pioneer Professor Thaddeus Lowe. Today we show a picture of the ground operations as his balloon is being prepared for flight. His balloons used a hydrogen gas as the lifting gas. The gas was produced by a process of partial combustion of coal or coke. One assumes that this combustion and generation is taking place in the two wagons at the left of the picture. This picture was taken at the Battle of Fair Oaks, where Lowe's flight provided valuable reconnaissance.
