Sprouting Wings (part 2).

Abstract

"Charles Green, a resident of London, did for balloons what Ford did for automobiles. He made them cheap. It was in 1814 that he discovered coal gas would do equally as well as the more expensive hydrogen. An artist with a pen who made a specialty of forgery and spent most of his life in solitary confinement has saved more aviator's lives than any other man in the history of the world. This man is M. Lavin, a French gentleman, who didn't use his abilities to the best advantage."
