To Prevent Ship’* Rollins*A German engineer, Otto von Sclilick, who has been studying for man-y years the prevention of ships' rolling, believes the solution lies in a gyroscope. flerr Sclilick proposes to steady ships by mounting the gyroscope in the hohi, and liis first experiments on a large scale have been undertaken with an old torpedo boat. In this craft a gryoscope with a disc weiglng 1,030 pounds was mounted with a steam turbine which would rotate it at a speed of more than 2,000 revolutions a minute. The oscillations and pitching of the vessel were carefully measured before the steam was admitted to the turbine, and then when the turbine was put In revolution the motion practically ceased. So successful were these experiments with the sixty-ton torpedo boat that ft has been decided to proceed with a larger cruft.
