Suddenly the wind ceased. The air seemed motionless around us. We were off, going at the speed of the air-current in which we now lived and moved. Indeed, for us there was no more wind; and this is the first great fact of spherical ballooning. Infinitely gentle is this unfelt motion forward and upward. The illusion is complete: it seems not to be the balloon that moves, but the earth that sinks down and away...

Villages and woods, meadows and chateaux, pass across the moving scene, out of which the whistling of locomotives throws sharp notes. These faint, piercing sounds, together with the yelping and barking of dogs, are the only noises that reach one through the depths of the upper air. The human voice cannot mount up into these boundless solitudes. Human beings look like ants along the white lines that are highways; and the rows of houses look like children's playthings."
