When a body left to f falls to. the surface of the bony it falls five feet in the first second; and if the same body were removed 257,542 miles farther off, in other words, to the distance of the moon, its fall would be re- duced to about half a line in the first second. That is almost equivalent to a state of perfect rest. Our business, then, is to overcome progressively this ac- tion of gravitation. The mode of accomplishing that is by the force of impulsion.” “There’s the difficulty,” broke in the major. * “True,” replied the president; ut we will overcome that, for . “Ordinarily the length of a gunn is twenty to twenty-five times t diameter of the shot, “and its weight two hundred and thirt five to two hundred and f times that of the shot.” cried “That is not enough,” T. Maston impetuously. “I agree. with you, my good friend; and, in fact, following this proportion for a projectile nine t in diameter, weighin hing 30,000 pounds, the gun would y have a length of two hundred and twenty-five feet, jand a weight of 7,200,000 pounds.” “Ridiculous!” rejoined Maston. “As well take a pistol.” “I think so too,” replied Bar- bicane; “that is why I propose - quadruple that length, and meres a gun of nine hundred ee “But,” said Elphinstone, “what thickness must we give it?” “A thickness of six feet,” re- plied Barbicane. “You surely don’t think of mounting a mass like that upon a carriage?” asked the major. - “It would be a superb idea, though,” said Maston. “But impracticable,” replied Barbicane. “No; I think of sink- ing this engine in the earth alone, binding it with hoops of wrought iron, and finally surrounding it with a thjck mass of masonry of stone and cement. The piece once cast, it must be bored with great precision, so as to preclude any possible windage. So there wi be no loss whatever of gas, and all the expansive force of the powder will be employed in the propulsion.” “One simple question,” said Elphinstone: “is our gun to $s force of impulsion will de-| rifled?” HOMES AP Newsfeatures’ .
