But, as her income diminished, so did her acquaintances fall off; and at the period of Isabel's return, with the exception of Mr Heaviside and one or two others, she was suffered to pine away in seclusion.
"If they are, why haven't we received evidence of it years ago?" "Because there has only been a hole through the heaviside layer for six years. Before that time they could not penetrate it any more than poor Hadley could with his space ship.
Why is it not possible that the Venetians, or Martians, or whoever our invaders are, have encased themselves and their space flyer in a layer of some substance similar to the heaviside layer, a substance which is permeable to light rays only when a large proportion of ultra-violet rays accompany the visible rays?
"Very rude indeed, madam; most excessively unpolite of Mr M . I should not have thought it possible." "Well, Mr Heaviside, as for Laura; poor thing! you are aware that she is not quite so clever as she might be; she never had any memory: when a child, she never could recollect the evening hymn if she missed it two nights running; so that acting was out of the question with her.
Carpenter's theory of the absorptive powers of the material of which the heaviside layer was composed was laughed to scorn by most scientists, who pointed out the fact that the sun, moon and stars could be readily seen through it. Carpenter replied that the rays of colored or visible light could only pass through the layer when superimposed upon a carrier wave of ultra-violet or invisible light.
He stated dogmatically that the amoeba and the other denizens of space absorbed all the ultra-violet light which fell on them and reflected only the visible rays which could not pass through the heaviside layer because of the lack of a synchronized carrier wave of shorter wave-length.
"If I may be allowed to see the letter, Mrs Revel," said the old gentleman "Oh, certainly, it's nothing but a note." Mr Heaviside read the contents. "There is very little in it indeed, Mrs Revel; not a word about the colonel, or why she left India. Perhaps the colonel may be dead." "Then she might have gone to live with one of her sisters, Mr Heaviside."
"Well, Mr Heaviside, we then thought that Charlotte, our eldest, had the next best chance of success. Although not by any means so good-looking as her sister; indeed, to tell you the truth, Mr Heaviside, which I would not do to every body, but I know that you can keep a secret, Charlotte is now nearly thirty years old, and her sister Laura only one year younger."
In 1887, another Englishman, A.W. Heaviside, laid circuits over two miles long on the surface and other circuits in the galleries of a coal-mine three hundred and fifty feet below, and established communication between the circuits. Working together, Preece and Heaviside extended the distances over which they could communicate.
The Attack from Space By Captain S. P. Meek "No one knows what unrevealed horrors space holds and the world will never rest entirely easy until the slow process of time again heals the protective layer." From "Beyond the Heaviside Layer." Over a year has passed since I wrote those lines.
