A reasonably definite date of the conception of the telephone somewhere in the summer of 1874 in Brantford, Ontario. The speaker's activities at the time. Recalling the circumstances under which the speaker first talked about his invention with his father. Drawings of the telephone's first conception by friends of the speaker. The telephone's "birth" in Boston in 1875. Canada's association also with a very important development of the practical telephone in the early days. The first transmission of speech over any distance in Brantford in August, 1876. Transmissions prior to that date. The importance of the experiments on the 10th of August, 1876. Recalling and describing the eight-mile call from Brantford to Paris, Ontario. How the first transmission was made, and the speaker's experience of it. The speaker's recent research work on aerial locomotion. The origin of the art of flying. The work of the late Professor S.B. Langley, Secretary of the Smithsonian Institution. The Wright brothers flight. The speaker's research into manned flight. Financial support from the speaker's wife to form "The Aerial Experiment Association." Member's contributions. Machines built and flown by this group. The future of flying. The part to be played in the conclusion of the war by the flying machine. At the beginning of aerial flight. Future development. Thinking about what may be accomplished: some theories. The speaker's line of reasoning, offered in the hope that some practical aviators in Toronto may perhaps be won over and may make experiments in this direction. Ideas as to how to get greater speed at a high altitude with the same power. Possibilities as to how to prevent the effects of the rarefied air upon a person's breath. The theory that the flying machine is supported in the air by the pressure of the air on the under surface of the wing. Changes in the future in relation to projectile flight. The possibility of the development of flight with engines without any wings. A concluding thought and question about flying without wings, as the speaker witnessed an albatross doing.
