"That," said Merna, "is a natural consequence of these influences; for they are in the air, so to speak, and have only to be brought into connection with the appropriate intellects to be assimilated and carried into effect."
I then asked him if he could explain how the influences acted; and he replied that in most cases they formed a sort of mental picture, which would be mentally seen and understood by a person sufficiently endowed with the necessary knowledge; but if he were not so endowed, or not receptive of new ideas, then he would learn nothing from the influences.
Thus a mental picture of some new and unknown piece of machinery would mean nothing to an unmechanical mind, or even to a mechanical mind which was not endowed also with the inventive faculty. In other cases only thoughts in the abstract could be sent, and these were more likely to remain unassimilated than the mental pictures, as a very high order of intellect was required to receive such thoughts.
I then informed him that our greatest and most daring electrician, Nicola Tesla, was firmly convinced that he had discovered planetary disturbances of an electrical nature which had reached our world. This occurred as far back as the year 1899; and, in the course of later scientific investigations, he found that the disturbances could not have come from the sun, the moon, or Venus. Further study has, he says, quite satisfied him that they must have emanated from Mars.
I added that Tesla was at work perfecting an apparatus which he was convinced would be the means of putting him into communication with other planets, by means of a wireless transmitter. This, he states, will produce vibrations of enormous power, and he has devised a means of producing oscillations of the most tremendous intensity. He states that he has actually passed a current round the earth which attained many millions of horse-power, and feels assured that he has already succeeded in producing electrical disturbances on Mars by the aid of this current. "Those disturbances," he adds, "are much more powerful than anything which could be obtained by means of light reflectors, no matter how large such reflectors might be, or how wide an area they might be made to cover."
