TRANSATLANTIC CINEMA NEXT.
London, May 27. The "London Daily Mail" has BUCCOBAfully tested Mr. John' Baird's television invention, using ordinary telephone wire.
A speaker in London was enabled to be both seen and heard in Glas- gow 438 miles away. This test cclipses the 200 miles test carried out in America between New York
and Washington.
Mr. Baird's experts will leave for America in a week's time in order to organise a wireless Tran- Atlantic television test.
A previous message states that cinematograph pictures of persons moving in total darkness were suc- cessfully transmitted wirelessly by Mr. John Baird, the inventor of the Televisor, by means of an invisible
ray.
The transmission of wireless mo- tion pictures is dependent upon the use of an intensity bright light which is suficient almost to blind the photographed person whose image is projected on the screen. It is broken up inte tiny flickering wirelessly particles which are
the transmitted and reflected on receiving screen where it assembles with such amazing rapidity that it deceives the human eye.
Now Mr. Baird has invented an amazing new invisible ray which enables the human eye actually to ace in darkness.
Result of Six Months Experiments. Representatives of the "Daily Mail witnessed the demonstration, which is the first apart from the secret tests before naval, military and Air Force officials.

Sydney, May 24. Gradually the closed book of European broadcasting is being opened to Australian listeners,

successfully received here, there is no reason why Con- tinental transmissions should not be heard by the same method of double, re-broadcasting.
"All these waves move at the rate of 186,000 miles a second, and it is among these waves of light that there is discovered a wave of a cer- tain length which makes broadcast- ing possible.
"You observo what a miracle it all is, that what we see is to what we cannot acelas 1 to 62. We think we see; we see only 1 in 62 of the things that are there to be seen if we could see them.

Radio-Paris transmits on 1760 metres; Voxhaus, on 566 and 483.9 metres; and Radio-Wien, on 577 and 517.2 metres. The date of the experiment has not yet been fixed.

This representative says that the fidelity of the image was perfect, thus accomplishing the apparent miracle of seeing a distant person who was sitting in darkness illu- minated by an 'invisible ray.
TALKS TO MARS.
What of England? And it is regrettably true that no credit is due to England. Station 2LO, London, did nothing more than send its usual programme at the usual times on the usual wave length. Is it not time that England had its own short wave station, capable of retransmitting B.B.C. programmes?
Not long ago, Captain Eckersley, chief engineer of the B.B.C., gaid that England was not prepared to build such a station, as it was by no means certain that programmes sent out in this way would be re- celved in the Dominions. And while Captain Eckersley was talk- The invention opens astonishing possibilities.

SUGGESTIONS FOR SOLVING CROSS-WORD PUZZLES
Start out by filling in the words of which you feel reasonably sure. These will give you a clue to other words crossing them, and they in turn to still others. A letter belongs in each white space, words starting at the numbered squares and running either horizontally or vertically or both.
