During his telephone experiments he learned the power of a diaphragm to take up sound vibrations, and he had made a little toy that, when you talked into the funnel, would start a paper man sawing wood. Then he came to the conclusion that if he could record the movements of the diaphragm well enough he could cause such records to reproduce the movements imparted to them by the human voice.
Moreover, about this time the colonists felt in the frame of the island vibrations which alarmed them to the highest degree. It was the 20th of February. Yet another month must elapse before the vessel would be ready for sea. Would the island hold together till then? The intention of Pencroft and Cyrus Harding was to launch the vessel as soon as the hull should be complete.
Now science has been able to compute just how many complete vibrations a certain note, key, or pitch as you may please to call it, makes each second, or how many times the particles of air vibrate back and forth when that especial note is sent out.
This machine was too nicely adjusted; a hint, the merest trifling expression of regret or doubt, sufficed to set the family soul so sympathetic vibrating. No one desired that harm should come of these vibrations far from it; they were set in motion with the best intentions, with the feeling, that each member of the family had a stake in the family soul.
I have been told that when a message is to be sent by wireless telephone, the other waves of sound must be quite still before the person receiving the message can hear it. The speaker has to wait till the vibrations settle down, there must be perfect stillness, and then the voice is heard. How important it is to shut out all other sounds so that our hearts may be still enough to hear God speak.
But the difference in the phænomena to which it will give rise is immense: in the first place it will develop a vast quantity of physical force cleaving the water in all directions with considerable rapidity by means of the vibrations of the long filament or cilium. Nor is the amount of chemical energy which the little creature possesses less striking.
The rhythm of these wasps was very different. They were peaceable, not even resenting the devastation of their home, but always and always must the inexplicable beat, beat, beat, be kept up, serving some purpose quite hidden from me. During succeeding months I found two more nests, with similar fetish of sound vibrations, which led to their discovery.
At any rate, though he had committed himself as to their general fatuity he put up with their company, for the sake of Miriam's vocal vibrations, with a practical philosophy that was all his own. And she frankly took him for her supreme, her incorrigible adorer, masquerading as a critic to save his vanity and tolerated for his secret constancy in spite of being a bore.
On regarding her more steadily, I saw that her whole body was trembling in gentle and yet seemingly intense vibrations, and she maintained this singular agitation while she assumed an attitude of much grace, extending her arms and spreading out her scarf in gracefully-waving curves.
The bells kept ringing, now filling the attic with their vibrations, and then receding to a faint and far-off clamor as the wind swept by. They called to all the bluff-dwellers within miles of Kaskaskia. The children sat down, and leaned their heads against their mother's knee. The others waited in drawing-room chairs; feeling the weariness of anxiety and broken domestic habits.
