PARIS AERO SHOW.
THE Societe Zodiac is yet another of those firms who have, during the past year, adopted the fuselage and the engine-in-front position on their biplanes. In its superficial appearance, their machine closely resembles the Antoinette, with the exception that a staggered biplane cellule is employed for sustaining in place of the latter's single spread of wing. Throughout its whole length the main body is of rectangular section, being constructed on the conventional lattice-girder principle, and is covered in with fabric.
At its rear end is arranged a horizontal empennage, the elevator flaps, and the directional rudder. Even as regards its landing chassis, the machine preserves its resemblance to the Antoinette. In its springing, however, it employs a different principle. From the axle uniting the two wheels proceeds a vertical mast of steel tubing, which is further stayed thereto by diagonal tubes on either side. From the upper extremity of this mast, the remainder of the aeroplane, consisting of the main body and the sustaining surfaces, is virtually slung, this being carried out by means of a series of brass-capped cotton-covered shock-absorbers. A substantial skid, shaped like a hockey stick, extends forward to protect the propeller. Balancing is controlled by the employment of ailerons.

THE PARIS AERO SALON.
THE Zodiac biplane has made no visible change at all since last year, except for the addition of a transparent shield above the pilot's and passengers' seats. Our sketches show this point, and also give a general idea of the machine.
It must be a wonderfully efficient biplane, for it must be no mean weight, and it does all sorts of passenger-carrying work with a 50-h.p. Gnome engine. The high aspect ratio of its planes must be responsible for this, as well as the saving in head resistance of a neat and clean chassis. One thing, by the way, we must mention; it is extremely welcome - after having had explained a dozen or so machines in rapid French - to come across one who speaks such excellent English as M. J. Labouchere, who flies the Zodiac, and who is looking after the firm's interest at the Salon.
