Dear Editor:
After reading Mr. Greenfield's letter in your April issue regarding my story, "An Extra Man," I feel that I should like to call his attention to a point which, it seems to me, he has overlooked, namely, that the reconstructed men were not composed of the original physical matter of the disintegrated man but of identical elements, all of which are at present known and available to science.
According to the hypothesis, Drayle could have produced as many entities as he desired and provided for, just as a radio broadcast is reproduced in as many places as are prepared for its reception. The vibrations alone are transmitted, and the reproduction is the result of a reciprocal mechanical action by physical matter at the receiving end. Any radio engineer knows that the original sound waves are not transported, but merely their impress upon the electrical radio wave. So, Drayle's disintegrating and sending apparatus only transmitted the vibrations which enabled his machines at the receiving end to select from a more than adequate supply of raw material, in due proportion and quantities, as much as was required for the reproduction of the disintegrated entities.
I think that if Mr. Greenfield will reread the story, noting the following references, he will agree that if the hypothesis is accepted the conclusion is logical:
1—It is only Jackson Gee and not Drayle who speaks of transmitting the constituent elements by radio (page 120).
2—The scientist, Drayle, says, (page 129) "We already know the elements that make the human body, and we can put them together in the their proper proportions and arrangements; but we have not been able to introduce the vitalizing spark, the key vibrations, to start it going." He does not say that tangible matter can be transmitted by radio.
3—In the account of Drayle's preliminary experiments (page 122) there is no statement to the effect that the original material composing the disintegrated glass was used in its recreation.
4—There is nothing in the story to indicate that the original physical composition of the disintegrated man was transported, in any manner to any outside location. The process of disintegration was necessary to obtain the vibrations that would make possible their repetition, which under proper conditions would induce a reproduction of the original, just as a song must be sung before it can be reproduced upon a phonograph disc, but which, once recorded can be repeated times without number.
5—Drayle's question (page 124) "Have you arranged the elements?" refers to the elements out of which all mankind is composed and which Drayle has previously mentioned (page 120).
6—The narrator emphasizes this aspect of the discovery when he says, on page 124, "I seemed to see man's (not the man's) elementary dust and vapors whirled from great containers upward into a stratum of shimmering air and gradually assume the outlines of a human form that became first opaque, then solid, and then a sentient being." And again (page 126), "The best of the race could be multiplied indefinitely and man could make man literally out of the dust of the earth." This does not imply a split-up of one individual into several smaller sizes or fractional parts, but rather the production of identical entities exactly as thousands of phonograph records can be created from the master matrix.
