They have no leaders only the sectional leaders of the secret society we organised before your very opportune awakening. Mere busy bodies and sentimentalists they are and bitterly jealous of each other. None of them is man enough for a central figure. The only trouble will be a disorganised upheaval. To be frank that may happen. But it won't interrupt your aeronautics.
As a result of this disaster endeavours were made to persuade Count Zeppelin to abandon the use of aluminium for the framework of his balloon but they were fruitless, a result no doubt due to the fact that the inventor of the airship of this name has but a superficial knowledge of the various sciences which bear upon aeronautics, and fully illustrates the truth of the old adage that "a little learning is a dangerous thing."
Last fall, for example, 91 percent of the Indian children between the ages of 6 and 18 on reservations were enrolled in school. This is a rise of 12 percent since 1953. In the field of science and technology, startling strides have been made by the new National Aeronautics and Space Administration.
"Having from a long experience in aeronautics been convinced that a constant and regular current of air is blowing at all times from west to east, with a velocity of from twenty to forty and even sixty miles per hour, according to its height from the earth, and having discovered a composition which renders silk or muslin impervious to hydrogen gas, so that a balloon may be kept afloat for many weeks, I feel confident with these advantages that a trip across the Atlantic will not be attended with as much real danger as by the common mode of transition.
Turning away from all those early and fanciful speculations, we now come to that period in the history of balloon voyaging, or aeronautics, when true theories began to be philosophically applied, and ascending into the skies became an accomplished fact.
The glider in question was exhibited at the Aeronautical Exhibition of 1868. Until the Wright Brothers definitely solved the problem of flight and virtually gave the aeroplane its present place in aeronautics, there were three definite schools of experiment.
The prime rôle of cavalry, reconnaissance, seemed to have passed from it. In addition to my normal duties, I visited France, Germany and Italy, collected information on foreign activities, wrote reports, and tried to create a knowledge of the possible effect of future military aeronautics and to urge the formation of a flying corps.
The period from 1885 to 1900 was one of unexampled activity in aeronautics, and for a time there was high hope that the age of flying was at hand.
The United States paid tribute to British efficiency by adopting the British system of training for its pilots; 500 American cadets were trained at the School of Military Aeronautics at oxford, in order to form a nucleus for the American aviation schools which were subsequently set up in the United States and in France.
That is not to say that the lifting screw must be totally ruled out so far as the construction of aircraft is concerned. Much is still empirical, so far as this branch of aeronautics is concerned, and consideration of the structural features of a propeller goes to show that the relations of essential weight and effective area do not altogether apply in practice as they stand in theory.
