 "Santos-Dumont No. 1," as it has since been called to distinguish it from those which followed—lay stretched out on the turf amid the trees of the beautiful Jardin d'Acclimatation, the new Zoological Garden of the west of Paris. To understand what happened I must explain the starting of spherical balloons from such places where groups of trees and other obstructions surround the open space. When the weighing and balancing of the balloon are finished and the aeronauts have taken their place in the basket the balloon is ready to quit the ground with a certain ascensional force. There-upon aids carry it toward an extremity of the open space in the direction from which the wind happens to be blowing, and it is there that the order: "Let go all!" is given. In this way the balloon has the entire open space to cross before reaching the trees or other obstructions which may be opposite and toward which the wind would naturally carry it. So it has space and time to rise high enough to pass over them. Moreover, the ascensional force of the balloon is regulated accordingly: it is very little if the wind be light; it is more if the wind be stronger. I had thought that my air-ship would be able to
