APRIL 17, 1909. models which, for lack of any evidence to the contrary, were presumably intended to represent their designers' ideas of a full sized machine, was distinctly devoid of real originality. Many exhibitors seem to have overlooked the fact that it is no longer a matter for conjecture as to whether an aeroplane can be made to fly and that it is, therefore, no longer sufficient that a model of this type should crudely suggest an arrangement of surfaces in bi- plane or triplane form. Many of the exhibits, as, for instance, those which represented aeroplane surfaces placed with their- greater dimension fore and aft, were directly opposed to accepted theory, while others less funda- mentally at variance were still more vague in their expression of definite purpose. Obviously those who appearance of substantial construction. The Orleans Co., too, brought over a number of the toy flyers which have been very successful in France, and Mr. E. W. Twining showed a beautifully made little toy biplane of the Wright type, but without a rudder. It was Messrs. T. W. K. Clarke's exhibit of the Wright flyer complete with its start- ing apparatus that constituted the most important and praiseworthy model in that category which included the copies of known machines, wherein special mention must also be made of a copy of the Henson-Stringfellow model in the South Kensington Museum which the Aero Club themselves had constructed by Short Brothers. Of this, and of the other devices, we now give the following more specific particulars :— MODELS AT OLYMPIA. 1. Piffard. 2. Howard. 3. Shapland. 4. Deixler. 5. Taylor. 6. Scnecal.

It is as an example of this latter aspect that the model exhibited by Mr. J. D. M. Tinline stands out pre- eminently, for therein a definite idea concerned with automatic control is given concrete expression. Lifting machines proved a fascination for some exhibitors, and one particularly extraordinary piece of mechanism be- longing to this class was the so-called "fan-shutter," exhibited by Mr. W. Mark. Among the toys, that is to say, the models which were fitted with elastic or clockwork propulsion, for actual flight, there was a higher degree of workmanship, the flyers constructed by Messrs. T. W. K. Clarke and those exhibited by Mr. Montford Kay having at least a pleasing DESCRIPTIONS OF THE MODELS. arched surfaces making the centre and at the ex- Bahle.—Biplane having dihedral angles in pairs at tremities. Batchelor.—Unfinished model of a helicopter, repre- senting the use of lifting screws in conjunction with a circular aeroplane, the latter being designed to increase the efficiency of the lifting screws, and also to enable the machine to glide. Blackburn.—Large model biplane fitted with vertical rudders between the main planes and a biplane tail at the rear. Clarke, T. W. K.—Models in wood of the Voisin and Wright flyers, the latter including the starting apparatus. The constructive detail of the Wright model is an excellent example of small scale woodwork. There were also shown double monoplane toy flyers fitted with elastic propellers. 222
