such education, when once instilled into the mind of the would-be aviator, becomes part and parcel of his mental make-up and goes a long way toward creating in the aviator's temperament the supreme qualities of foresight, forethought and caution, the exercise of which is the fundamental requisite to safe and sane flying.      Secondly, an explanation as to the wrong ideas and false notions which most of the public have regarding the sensations in aerial travel, is comprehensively given. This is followed by an exact description of the sensations experienced by the lecturer while traveling through the air.

Capt. Horacio Ruiz, of the Mexican Army, making a spiral glide under the supervision of his instructor, Mr. Jerwan.

Such description, accompanied with stereopticon views, gives the audience an exact idea of a sensation similar to that of an automobile's minus the friction, the vibration and jars caused by passing above ditches and bumps, plus a birdseye view of the surrounding country.      Lastly, the author concludes with a forecast of the development of safety devices for stability in the air which is the forerunner of the utlimate success of the flying machine, not only for scouting purposes but for commercial every day use.      On the whole, the lecture cannot fail to interest both the professional and the layman, inasmuch as it is intended to demonstrate in a clear and comprehensive way the working mechanism of the eighth wonder of the world--the flying machine.
