Here, without the use of a battery, with no more electric current than that made by a couple of magnets, all the waves of a sound had been carried along a wire and changed back to sound at the farther end.
If a tuning-fork could be made to sing by a magnet or an electrified wire, why would it not be possible to make a musical telegraph--a telegraph with a piano key-board, so that many messages could be sent at once over a single wire?
There was no way of finding out, however, until Tom had a chance to talk to Ned, and at present the young scientist was eagerly listening to what came over the wire
. Occasionally Ned could hear him say:
"I will make no medicine," he said, "until I have the goats and the mat and the copper wire."
Bukawai saw them go, and he mumbled through his rotting face, swearing a great oath that he would yet have the three fat goats, the new sleeping mat, and the bit of copper wire.
There were books, rifles, revolvers, ammunition, cameras, chemicals, telephones, telegraph instruments, wire, tool and more books--books upon every subject under the sun.
Constantly my eyes scanned the blinding waste of sand for the ricky cairn beneath which I was to find the wires leading to Pellucidar--but always was I unsuccessful.
Watching the rigging up of the barbed wire, Jerry's next adventure was an encounter with Lerumie, the return boy from Meringe, who, only that morning, on the beach embarking, had been rolled by Biddy, along with his possessions into the surf.
Jerry, scarcely aware of Lerumie's presence, was trotting past on his way aft to where Borckman, the mate, was superintending the stringing of the barbed wire to the stanchions.
Edgar took up a small wooden box, through a hole in which the wire
of the runner ran.
It's up to you, just according to how you pull the wires
. Come on.
Does the answer lie somewhere upon the bosom of the broad Sahara, at the ends of two tiny wires
, hidden beneath a lost cairn?
