~Motors.~--2 Clement motors, 4-cylinder, of 130 h.p., each placed on either side of the motor space. ~Speed.~--35 m.p.h. (56 km.) ~Propellers.~--2 Chauviere. Diameter, 19-3/4 feet (6 m.) Placed one on either side of the motors, well above the level. ~Steering.~--Vertical steering by means of a treble horizontal rudder over the rear end of the car. Horizontal steering by means of 2 vertical rudders placed one on each side of the rear horizontal rudder. Remarks.--The feature of this _C.B._ type, which distinguishes it from the Astra ships of about the same size, is the arrangement of the propellers and the use of a 2 speed gear in connection with these. Normally each motor drives its own propeller through two sets of gearing connected by a Cardan shaft. On stopping one motor, the stopped motor is unclutched from its propeller shaft, which is then connected up by chain drive to the opposite shaft. The running motor is then put on to a "low gear," so that it can make the revolutions necessary for obtaining full power, while the propellers run slower than before. The ratio of "low gear" to "high" is 2 to 1, so that a single motor will be running under its best conditions when well throttled down. A sister, _C. Bayard II_ was sold to the British Army, and wrecked or dismantled, 1911. LIST OF WEIGHTS. kgs.

Military. (C.B. V.) (1912.) C. BAYARD VI. (Private.) (1913.) These two are slightly smaller sisters of the _Adjutant Vincennot_. =LEBAUDY CLASS.= Ateliers Lebaudy Freres, Moisson, par La Roche-Guyon (Seine-et-Oise). ~DISTINCTIVE CHARACTERISTICS:~ The cars are short and suspended from a long keel which is suspended close up to the gas bag, and is mostly covered in with fireproof canvas. The rear end of the keel is expanded into fixed vertical and horizontal fins, and carries a vertical and a horizontal rudder. The rear end of the gas bag is fitted with thin fixed planes (compare with the pear shaped or tubular fins of the "Astra" class).
