forming a continuous life-buoy, effectually floats the whole length, and constant sound 

 proclaims the arrival or whereabout, produced by the compressed air which constitutes the 

 propelling force supplied from land, wherefrom it can also be steered and lighted by electricity. 

 The Turbin 'or Siren in this case acts threefold : 1st, Constant sound ; 2nd, Atmospheric 

 propulsion; 3rd, mechanical force to screw propeller. The hose is effected fivefold: 1st, the 

 hose a controller; 2nd, continuous life-buoy; 3rd, conductor for compressed air; 4th, trans- 

 mission of sound ; 5th, cover to electric connection.
