'(J. - A Afternoon Dresi of Green VeWet, Green Chlffos Bodice and Chinchilla Collar Petticoat and Sleeves Made in One Garment The Gyroscope Will Solve the Problem of Aerial Navigation and Torpedo Warfare M By LEON LECORNU, of the FrencTi Institute. EIGHTEEN months ago If one staked la a Fifth Arena shop to be shown some petticoats, the yonng Udr In attendance would look at one with a blank "I-dont know-what-you-mean" look. "Petticoat T" she would re peat. "On, res, 70a mean for old ladies, madam," and would direct you where you might find some comforting woollen garments that one sends la one' Christmas bun dies to the poor, this being the only kind of petticoat known in the time of the tight skirt. To-day one cannot enter a ehop without being faced with rows of multi-colored, much befrlUed and beflowered delight ful creations that are to be worn under the full ekM that hare taken their place. 'To my mind the petticoat, like a 'hat, boots or glores, must be lndlridual with the garment.. That la why so many of my dresses are made with the petticoats actually at tached and made Into the gown with which they are to be worn. I am making petticoats In endless Tarieties and of endless methods. Some are made frilly and fluffy, to be worn underneath the hooped skirt) some are made with hoops In them, to be worn underneath a fully cut skirt that Is not hooped; some are trimmed with flowers, lace, embroidery. I hare a delightful little gray dress, simple and quite Puritan In cut, while the petticoat Inside la of black and white embroidery orer the usual flesh-colored foundation. It Is so amusing to see this little taffeta dress Just caught up, as it by accident, at the side, displaying this Urtling undergarment, somewhat bold In design, the black being of inlets of tulle and the embroidery belns of floss silk and run with black ribbon. The pictures I hare chosen this week are particularly suitable to my above talk, because each of them has a petticoat of Its own. While each In a way is of different style so far aa the dress goes, two are of picture persua sion, while two are distinctly modern, though, of course, I don't say the picture dresses are not modern, too, aa practi cally every smart gown of the moment la borrowed directly from the early '0's or '40's of the last century. The little sprigged taffeta made over a hoop has a pet tlcoat made of a succession of Valenciennes frills, with a line of skunk and more Valenciennes with tiny bouquets of flowers above that. The little bodice Is tight and pointed, girdled with shades of lavender and green, while the small ruchlng on the basque and sleeves and bonnet match thoJe on the petticoat. To the right la a little stiff satin gown embroidered In. rose color, over a petticoat made with hoops In It, while pink and silver striped satin form the bodice. Petticoat and" sleeves are made In one garment, coming through armbolea on the shoulders, which. Is of silver lace.

Chinchilla also Is worn on the canary colored hat. The little evening dress at the bottom la of silver gray and black Jet embroidered tulle, with a steel colored bodice and a flesh and silver petticoat. AKE the aeroplane stable; make It impossible for it to turn over or lose Us balance and the problem of aerial naglvatlon Is solved. Is the admission of most scientists. To understand the principle of the gyroscope we have to begin at the beginning. If you look at a child's top spin ning rapidly It seems motionless. Its outward aspect does not change at all; each particle of its mass leaves Its place only to be replaced by an Identical 'element. Yet It is possessed of certain properties very different from those possessed by It when at rest. If after placing tfte point In- a fixed cup thla top la left to the action of gravity It will be observed that the axis, Instead of falling vertically, preserves a constant Inclination and begins to describe a cone, about the vertical, starting from the point. What is it that is the cause of neutralizing this action of the weight? It Is not enough to say that the rotation develop centrifugal forces which pull upon the axis. These centrifugal forces act equally upon all part and are - Incapable of preventing the fall. If the' axis does not fall It Is because, aa Its direction changes, new forces are en gendered, called in mechanics "compound centrifugal forces," the purpose of which Is directly to counteract the weight. Calculations have demonstrated that , they act . upon the axis to displace It conicaUy, and to this we give the name precession, which verifies our experience, for if we prevent the precession from acting the axis falls at once, and, inversely. If we press upon the axis to Increase the precession the axis rises more and more. These curious properties of the top may be generalised, leading us to the Idea of the gyroscopto or gyrostatic effect. In this way we learn that if a body entirely sym metrical to its axis is turned rapidly on that axis, of which one point remains fixed, If we apply force to any other point of that axis It will be found to move, not In, the direction of that force, but in a perpendicular direc tion, with a rapidity which, other things being equal, Is In inverse proportion to the rapidity of the rotation. The axis is thus more stable than the rotation and more rapid and, besides, It sways laterally Instead of obeying directly the pressure brought to bear upon it. An experiment will show this clearly. Take a solid ring, the axis of which la supported at each end In some way, and after giving the ring rapid rotation try to swing the support. At this moment we feel the same sensation as If an invisible hand had caught hold of the apparatus and given it a perpendicular twist away from what w want to do. A savage trying this for the first time would deem himself in the presence of a mysterious divinity. If a stone or wooden egg be placed upon a table and spun quickly the egg will be seen to rise on one of Its ends, showing the gyroscopic action. This must be dona with a more or less rough egg to secure the friction on the table. At a meeting held In the Royal Institution of Great Britain, February 14, 1913. Professor Andrew Gray, of the University of Glasgow, demonstrated a variety of gyro scopic apparatus, one adapted to a bicycle, showing bow It was balanced automatically and perfectly. The earth Itself is a huge gyroscope, a ball, with flat tened enda and broadest at the equator. If this great top were not subject to outer attractions Its axle would pre serve the same Inclination Invariably. But astronomical observations prove that in reality this axis possesses a precessions! motion around the perpendicular In the plane or the ecliptic; that Is to say, In the plane of the orbit de scribed by the earth around the sun. The movement I so stow that the complete revolution takes 26,000 years, bat Its existence Is plainly established and has, as a conse quence, the precession of. the equinoxes, discovered by the Greek astronomer Hlpparchus. Here, too, w are In the presence of a gyroscopic effect. The perturbing force I the attraction exercised by the sun (and also by the moon) upon the equatorial expansion. If the earth did not revolve this attraction of th sun would be felt by that part of the equator nearest to It, forcing the line of the poles to change perpendicularly to the i ecliptic, causing the disappearance of the aeasons. but the earth does revolve, and the attraction of the poles becomes a conical precession. The rotation of the earth has been proved by the gyroscope, but more than that th gyroscope can be and I applied to the compass, so that It is always kept perfectly true and pointing as It should. The metal mass of the modern ship does not affect the gyroscopic compass as it does the ordinary compass. The gyroscopic compass is of great value because It Ukes the same Inclination as the line of the pole and thus Indi cates the latitude to the captain of the ship or aeroplane. The application of the gyroscope to submarine tor pedoes has increased the efficiency of these awful Imple ments of warfare manifold. It Is Impossible to give the enormous msss of the torpedo the revolving motion given to a shell when fired from a cannon, but each one of the torpedoea has its own small gyroscope at the back, which preserves the balance perfectly and aids enormously in the scoring of a ahot. Gyroscopic principles have been applied, only very lately, to the perfecting of turbine engines In which the revolutions must be very rapid and where great difficulty was found until automatic regulators of the shafts were supplied, and these on gyroscopic principles. .Oyroscoplc effects are spparent in any turning body, no matter what the size. The earth itself acts like a huge gyroscope. At the other end of the scale, molecules of matter. If, as we suppose, they are In constant revo lution, are affected by the same laws. According to De Heen, the phyelclst knows neither inflammability, nor cor puscles, light, maanetlsm, nor electricity; he deals only with gyrostats and living vortices. Bogaert holds that It we take account of the gyroscopic properties of molecules we may, perhsps, abandon certain bold doctrines which tend to diminish the principles of mechanics and notably to destroy the Idea of mass. The fall of an apple led Newton to the discovery of gravitation, which governs the astronomical world. Why, then, may not the child's top, which, on the contrary, re fuses to fall, reveal to us the mysteries of the world of atoms? Cvtaiiu,. IfUSt bf u Sr CeMWagr. Qmt Bnuia JtifbK Bvt
