There are limitations to this delightsome way of talking. A person can hold conversation with only one absent friend at a time and then only when each one concentrates his thoughts on the other. What wireless telegraphy is to our world, this mental conversation is to the world of Mute, and it is possible that we may reach a higher degree of proficiency in this direction after we become still better acquainted with the laws of the human mind.
When I think of the many unaccountable heart-thrills that send their emotions of joy and hatred into our passing life, I am somewhat persuaded that we speak this tongueless language more than we imagine. Some day we may learn the secrets that are now so heavily veiled and thereby put to naught the glory of our present modes of communication. Until then we will plod along with the telegraph, telephone, wireless telegraphy and our ever-changing knowledge of telepathic intercourse.
I will give the philosophy of this perfect means of expressing thought as clearly as I can.
