Robur the Conqueror Read Online Free PDF Page A

walk on it with naked feet. Or if, by means of a screw, you drive a mass of air at this speed, you get the same result."
    What Robur said had been said before by all the partisans of aviation, whose work slowly but surely is leading on to the solution of the problem. To Ponton d'Amécourt, La Landelle, Nadar, De Luzy, De Louvrié, Liais, Beleguir, Moreau, the brothers Richard, Babinet, Jobert, Du Temple, Salives, Penaud, De Villeneuve, Gauchot and Tatin, Michael Loup, Edison, Planavergne, and so many others, belongs the honor of having brought forward ideas of such simplicity. Abandoned and resumed times without number, they are sure, some day to triumph. To the enemies of aviation, who urge that the bird only sustains himself by warming the air he strikes, their answer is ready. Have they not proved that an eagle weighing five kilograms would have to fill fifty cubic meters with his warm fluid merely to sustain himself in space?
    This is what Robur demonstrated with undeniable logic amid the uproar that arose on all sides. And in conclusion these are the words he hurled in the faces of the balloonists: "With your aerostats you can do nothing—you will arrive at nothing—you dare do nothing! The boldest of your aeronauts, John Wise, although he has made an aerial voyage of twelve hundred miles above the American continent, has had to give up his project of crossing the Atlantic! And you have not advanced one step—not one step—towards your end."
    "Sir," said the president, who in vain endeavored to keep himself cool, "you forget what was said by our immortal Franklin at the first appearance of the fire balloon, 'It is but a child, but it will grow!' It was but a child, and it has grown."
    "No, Mr. President, it has not grown! It has got fatter—and this is not the same thing!"
    This was a direct attack on the Weldon Institute, which had decreed, helped, and paid for the making of a monster balloon. And so propositions of the following kind began to fly about the room: "Turn him out!" "Throw him off the platform!" "Prove that he is heavier than the air!"
    But these were only words, not means to an end.
    Robur remained impassible, and continued: "There is no progress for your aerostats, my citizen balloonists; progress is for flying machines. The bird flies, and he is not a balloon, he is a piece of mechanism!"
    "Yes, he flies!" exclaimed the fiery Bat T. Fynn; "but he flies against all the laws of mechanics."
    "Indeed!" said Robur, shrugging his shoulders, and resuming, "Since we have begun the study of the flight of large and small birds one simple idea has prevailed—to imitate nature, which never makes mistakes. Between the albatross, which gives hardly ten beats of the wing per minute, between the pelican, which gives seventy—"
    "Seventy-one," said the voice of a scoffer.
    "And the bee, which gives one hundred and ninety-two per second—"
    "One hundred and ninety-three!" said the facetious individual.
    "And, the common house fly, which gives three hundred and thirty—"
    "And a half!"
    "And the mosquito, which gives millions—"
    "No, milliards!"
    But Robur, the interrupted, interrupted not his demonstration. "Between these different rates—" he continued.
    "There is a difference," said a voice.
    "There is a possibility of finding a practical solution. When De Lucy showed that the stag beetle, an insect weighing only two grammes, could lift a weight of four hundred grammes, or two hundred times its own weight, the problem of aviation was solved. Besides, it has been shown that the wing surface decreases in proportion to the increase of the size and weight of the animal. Hence we can look forward to such contrivances—"
    "Which would never fly!" said secretary Phil Evans.
    "Which have flown, and which will fly," said Robur, without being in the least disconcerted, "and which we can call streophores, helicopters, orthopters—or, in imitation of the word 'nef,' which comes from 'navis,' call them from 'avis,'
