Arsenate of Lead Zeppelin -- 1923
In this 1923 photograph, a 106-foot long U.S. Army Zeppelin soaks the town of Deering, New Hampshire with arsenate of lead during a gypsy moth infestation. According to the photo source, some of the cement used in supporting the control cabin mounted under the Arsenate of Lead Zeppelin loosened during discharge of the first load of insecticide. It could not be repaired and was deflated and returned to Dayton, Ohio. (USDA Forest Service Archive Photo)
