In truth the mastery of flying was the work of thousands of men--this man a suggestion and that an experiment, until at last only one vigorous intellectual effort was needed to finish the work. But the inexorable injustice of the popular mind has decided that of all these thousands, one man, and that a man who never flew, should be chosen as the discoverer, just as it has chosen to honour Watt as the discoverer of steam and Stephenson of the steam-engine. And surely of all honoured names none is so grotesquely and tragically honoured as poor Filmer's, the timid, intellectual creature who solved the problem over which the world had hung perplexed and a little fearful for so many generations, the man who pressed the button that has changed peace and warfare and well-nigh every condition of human life and happiness.
