The detector was, however, an English seaman, now captain of a well-known steam-vessel, who forming part of a crew one of whom had lost a sum of money, broke off ten twigs of equal length from a broom, and distributed them among his shipmates, with the same observation as was used by the Argentine chief.

"Eleven, M.P.", however, could mean nothing to anybody but Victorexcept a body clever enough to hide a dictograph detector in a turnip.

The coherer has been displaced by a new device invented by Marconi, called a magnetic detector, by which the ether waves are aided by a stronger current to record the message.

We'll have to develop a detector that uses a process other than radar-perhaps something based on gravity or light absorption.

And superlatively happy are they who can lay calmly down on the bed of death cheered by her approving smiles, for a "death bed is a detector of the heart;" here tired dissimulation drops the mark that through life's grimace has kept up the scene.

Thus sound is converted into waves, and the receiving station, as you see here, with its aërial on the roof, its detector, its 'phone and its tuner, gets these waves and turns them again into sound.

The 'phone receivers and the crystal detector will have to be purchased as well as some of the accessories, such as the copper wire, pulleys, battery, switches, binding posts, the buzzer tester and so forth.

"By the time we go camping I'll know a cat track from a squirrel's, or never put a detector on my head again." Piloted by Frank, the two young scouts made their way to the office of the local paper, which had already placed a large bulletin announcing the aeroplane model competition in its window.

The others gazed on admiringly as Hiram, having completed his message, adjusted the detector on his head and awaited an answer.

With the Branly coherer as the basis Marconi sought to make improvements which would result in the detector he was seeking.

To the devices of Carty and his associates was added the extremely delicate detector that was needed.
