� In the first place, it was soon found that it was possible to obtain greater efficiency and, in particular, higher speeds, from tractor machines than from pusher machines with the air-screw behind the main planes. This was for a variety of reasons connected with the308 efficiency of propellers and the possibility of reducing resistance to a greater extent in tractor machines by using a 鈥榮tream-line鈥?fuselage (or body) to connect the main planes with the tail. Full advantage of this could not be taken, however, owing to the difficulty of fixing a machine-gun in a forward direction owing to the presence of the propeller. This was finally overcome by an ingenious device (known as an 鈥業nterrupter gear鈥? which allowed the gun to fire only when none of the propeller blades was passing in front of the muzzle. The monoplane gradually fell into desuetude, mainly owing to the difficulty of making that type adequately strong without it becoming prohibitively heavy, and also because of its high landing speed and general lack of man?uvrability. The triplane was also little used except in one or two instances, and, practically speaking, every machine was of the biplane tractor type. � Bishop Meade further consoles slaves thus for certain incidents of their lot, for which they may think they have more reason to find fault than for most others. The reader must admit that he takes a very philosophical view of the subject.

She came to the wedding with the son and daughter of her second marriage; the latter was afterwards the celebrated Mme. de Montesson. But she managed permanently to cheat her elder daughter out of nearly the whole of the property of her father, and always behaved to her and to her children with the most heartless cruelty. � �
