 the 30,000 cycle, bul ihiy could not hear us talk when we are usinr; 

 a cycle below 30,000. There is one peculiarly notable fact and that 

 is. when the vibrations run into a clean mathematical ratio like a 

 common chord of say C, E, and Ci. and these are in the ratio of 4, 

 5. and 6. any vibrations of sound that are transmitted to our ear in 

 this ratio are pleasing and are the flominant chords in music. Octaves 

 above would be 8. therefore. 4, 5, 6, and. 8 would be a handful of 

 notes that makes the most harmonious sound in music. W'c run 

 across the same phenomena in light, for instance, the green and the 

 Vermillion rays which the Chinaman uses in his decorations are al- 

 most a perfect fifth, but the red of the geranium and the bougan- 

 villa produce a most horrible discord, not being mathematical to the 

 eye. I am bringing this matter up perhaps for the moral end of this 

 sermon. As I have stated before, we have an almost unlimited rate 

 of vibrations that do not affect our known senses. Flammarion, Ihe 

 French astronomer, has advanced the hypothesis that perhaps a great 

 many of these vibrations which we have been unable to study affect 

 us mentally. This may be the beginning of the study of mental tele- 

 pathy. Most of us have had some actual physical experience in this 

 ps}xhological study. Personally, I have had some very vivid ex- 

 periences myself. When we get down to real scientific experiments we 

 invariably feel that we do not know how to get at them. I believe 

 the time is coming when these unknown effects of vibrations can be 

 segregated and analyzed. We meet people, hear them talk, and are 

 thrilled, and why we cannot explain. We have seen a whole nation 

 change its idea from — 'T did not raise my boy to be a soldier," to 

 the slogan — "Treat 'em rough." This all in the course of a year, 

 and brought about by an extensive propaganda that affects every 

 human being. We have also seen epidemics of fear sweep over the 

 country which is the real psychological reason why we have financial 

 panics, people thinking and acting in mobs; strikes, labor unrest, 

 these are but the forceful examples of waves of thought that are 

 sweeping the country today and affecting all of our lives. In the 

 future development of humanity it is not too much to hope that we 

 can control the race, that we can "tune in" with what we want, or 

 we can "tune out" from what we do not want. We speak of a sales- 

 man being successful, that he is a good mixer, which is another way 

 of saying that he is a good synchronizer. This is a subject that may 

 well be studied out and practiced. If a man has complete control 

 of his thinker, he has cultivated the art of "tuning in" and can make 

 anyone like him, and can bring people to his way of thinking. If 

 he can think through the 4th, 5th, and 6th ratios, so as to harmonize 

 with other vibrations, which may take long years of study and prac- 

 tice, he will find that it is just as easy for the people in the world 

 to love each other as to hate each other and it is only a matter of 

 every man adjusting his condenser.
