n one lever spells up and down in the other spells right and left. It is a testimony to the extraordinary cool-headed skill of the Wrights, and to their endless practice and perseverance, that they were able to fly such a machine in safety, and to outfly their rivals. The French school centralized the control in a single lever with a universal joint attachment at the lower end. The movements of this lever in any direction produced the effects that would instinctively be expected; a backward or forward movement turned the machine upwards or downwards, a sideways movement raised one wing or the other so as to bank the machine or to bring it to a level position again. The vertical rudder was controlled either by a wheel attached to this central lever, or by the pressure of the pilot's feet on a horizontal bar. The French moreover improved the means of taking off and alighting. The early Wright machines were launched on rails, and alighted on skids attached to the machine like the skids of a sledge. To rise into the air again after a forced landing was impossible without special apparatus. By means of wheels elastically fixed to an undercarriage the French inventors made the aeroplane available for cross-country journeys. But the greatest difference between the two types of aeroplane, the American and the French, was their difference in stability. The Wright machine demanded everything of the pilot; it could not fly itself. If the pilot relaxed his attention for a moment, or took his hands from the levers, a crash was the certain result. The machine was a bird which flew with extended bill and without a tail; whereas the French machines had a horizontal tail-plane, which, being held rigidly at a distance from the main planes, gave to the machine a far greater measure of longitudinal stability. All these advantages told in favour of French aviation, and secured for it progress and achievement. A few dates and facts may serve to show its rapid progress at a time when it was making history week by week. On the 30th of September 1908 Henri Farman made the first cross-country flight, from Chalons to Rheims, a distance of twenty-seven kilometres, which he covered in twenty minutes. Three days later, at Chalons, he remained in the air for just under three-quarters of an hour, covering twenty-five miles, that is, about forty times the distance that had won him the Deutsch-Archdeacon prize in January.
