The only real education, that is to say, the only transmission to the children of the ideas of their parents consists of an education at home which is reinforced by the instruction of masters chosen by the parents in accordance with their own views. This is precisely the form of education to which democracy refuses to be reconciled.
To insure safe transmission of this communication, England had held the Assyrian idle in port, day after day, while her augmented patrols scoured the seas, hunting down ruthlessly every submarine whose periscope dared peer above the surface, and while her trawlers innumerable swept the channels clear of mines.
These two operations call for no extended consideration. We are at present concerned only with the psychological laws bearing on the muscular adjustments of the vocal organs. Muscular contractions result from the transmission to the muscular fibers of motor nerve impulses. These nerve impulses originate in the motor nerve centers. They can never, under any circumstances, rise into consciousness.
The high pressures required for the economical use of transmission lines necessitates the employment of transformers at each end of the line; namely, step-up transformers at the transmitting end, to raise the voltage delivered by the generators, and step-down transformers, at the receiving end, to lower it for use in the various translating devices.
Contrast with this the small district to be protected when it comes to a wireless station. Instead of having soldiers scattered through miles of territory the few needed can be concentrated within easy reach of provisions and reinforcements. And the same advantages that the radio telephone has on land prevail as well at sea for transmission of messages by cable is a frightfully expensive thing.
He could not call his students and tell them what was happening. The guard-ship would overhear. He could not trust untried young men to act rationally if they were unwarned and the guard-ship arrived and matter-of-factly attempted to board one of them. Then he was inspired. He called Murgatroyd, placed him before the communicator, and set it at voice-only transmission.
Philipp Reis, a simple professor in Germany, utilized this principle in the construction of apparatus for the transmission of sound; but in the grasp of the idea he was preceded by Charles Bourseul, a young French soldier in Algeria, who in 1854, under the title of "Electrical Telephony," in a Parisian illustrated paper, gave a brief and lucid description as follows: "We know that sounds are made by vibrations, and are made sensible to the ear by the same vibrations, which are reproduced by the intervening medium.
Where will the archaeologist of the year 12,896 turn for the history of our time where search for those "few immortal names that were not born to die"? Oral transmission of historic data, such as prevails among savages, such as prevailed among the Hellenes in the age of Homer, has been supplanted by the press.
But let us look at the other side also. Does science owe nothing to art? Only a short time since the illustrious French physicist, M. Tresca, was enumerating the various sources of loss in the transmission of power by electricity along a fixed wire, as elucidated in the careful and elaborate experiments inaugurated by M. Marcel Deprez, and subsequently continued by himself.
An observer, who wishes to appreciate that hum of civic life which he cannot analyze, will find an excellent opportunity by placing himself on the hill of Capo di Monte at Naples, in the line of prolongation of the street called Spaccanapoli. It is probably to the stillness of which I have spoken that we are to ascribe the transmission of sound to great distances at sea in calm weather.
