“ If a lighter motor is used, the size of the wheel hubs may be modified. These hubs are, as may be seen in the drawings, simply put on over the tubes and fastened by a cotter pin. The tubes should be allowed to extend out several inches beyond the end of the hub. Great care should be taken in the selection of this lower tube, for almost the entire weight of the machine comes upon it. It is not necessary to provide any special bearings for the wheels, as it is intended they should work with a slight friction. It may readily be seen that the wheels are inclined toward one another at the top. ”

“ It is of prime importance that the motor should be perfectly balanced. It should be direct connected to the axle holding the propeller. The gasoline reservoir is located behind the pilot's seat, the fuel being forced up into a smaller one just above the motor. In his remarkable flight from St. Cyr to Buc, the inventor of the monoplane used a two-cylinder Darraeq motor of 20 hp., which gave the propeller 1000 r.p.m. It weighed a little over 99 Ib. The entire machine weighed 260 Ib. without the pilot. ”

“ A side movement pulls the rear end of the wing opposite to the side to which the pilot leans. The balancing of the whole apparatus, is, therefore, in a manner, automatic. The pilot has but to bend over to one side in order to balance the machine. Springs are introduced on the wires which control the rudders of some of the machines so as to bring the rudder back to its normal position without effort on the part of the operator. The seat is a piece of canvas or leather stretched across the two lower bamboo rods just behind the wheels. ”
