Let these years be judged by the records they produced, and even then they are rather dull. The glory of achievement such as characterised the work of the Wright Brothers, of Bleriot, and of the giants of the early days, had passed; the splendid courage, the patriotism and devotion of the pilots of the War period had not yet come to being. There was progress, past question, but it was mechanical, hardly ever inspired. The study of climatic conditions was definitely begun and aeronautical metereology came to being, while another development already noted was the fitting of wireless telegraphy to heavier-than-air machines, as instanced in the British War Office specification of243 February, 1914. These, however, were inevitable; it remained for the War to force development beyond the inevitable, producing in five years that which under normal circumstances might easily have occupied fifty鈥攖he aeroplane of to-day; for, as already remarked, there was a deadlock, and any survey that may be made of the years 1912-1914, no matter how superficial, must take it into account with a view to retaining correct perspective in regard to the development of the aeroplane. Upon my honour, there's nothing I should like so much as to get away across the seas! And you might as well hint to my lord, in the course of your letter, that I should be very well contented with a berth in the Colonies. A good climate, of course! One wouldn't care to be shipped off to Sierra Leone! All communications will receive prompt attention. Chapter XXXV Ader鈥檚 work is negative proof of the value of such experiments as Lilienthal, Pilcher, Chanute, and Montgomery conducted; these four set to work to master the eccentricities of the air before attempting to use it as a supporting medium for continuous flight under power; Ader attacked the problem from the other end; like many other experimenters he regarded the air as a stable fluid capable of giving such support to his machine as still water might give to a fish, and he reckoned that he had only to produce the machine in127 order to achieve flight. The wrecked 鈥楢vion鈥?and the refusal of the French War Ministry to grant any more funds for further experiment are sufficient evidence of the need for working along the lines taken by the pioneers of gliding rather than on those which Ader himself adopted.

"Is it missus's writing?" she asked. Oh! I'm very glad. � Let Your kingdom reign over us now and forever. The Holy Men of old said remit and forgive unto all men whatsoever they have done unto me. And lead us not into temptation, but deliver us from the evil thing; for Thine is the kingdom and Thou shalt reign in glory forever and forevermore, AMEN.
