This consisted of a single selenium ate on which a lens threw an mage.

One hole would pass across the top of the plate. the next be- low it and so on until the disc had made a complete is ' ” . producing the illusion of a com- plete picture.

The Difficult Age Group . The eight to 12-year-old age group is perhaps the one that will give the most difficulty in connection with- television. The 10 or 12-year-old boy is beginning to have definite ideas and ' ' which differ from those of his parents He has his own ideas of what he should do and when he should do it. For example. the parent may find difficulty in con- vincing him that ll pm. is too late to stay up watching televis- ion and that he should have teen in bed much earlier.

STRAIGHT LINE From that central office the program is fed by more large coaxlals to a microwave trans- mitter siation outside the city. This microwave unit is much the same as a standard television station transmitter. except that it transmits on a different frequ- ency and in a perfectly straight line. So naturally the standard home television set can't pick it up because it hasn't the right frequency receiver, nor are very many of them on that straight line of transmission. Because this micro wave trans- mitter is on a high frequency and transmits in a straight line. it's signal won't curve around the earth and so can only be re- celved as far as the horizon. the same as light waves. This means that every thirty miles, there must be another micro-wave transmitter which receives the program from the previous one and relays it on. This necessitates a chain of micro wave towers all across the area from the original station to the television station that finally broadcasts the program. - As yet, Canada does not hav a cross country micro wave sys- tem. but one is being built and CFCY-TV is just one of the many television stations along the line of micro-wave relays that event ually will criss cross Canada from the Atliintlc to the Pacific.

Nearly everyone. at one tfmeor another. wonders how the tele- vision picturc gets to the screen of their TV set and sometimes a satisfactory explanation is dif- ficult to come by. The television picture is com- posed of tiny electrical impulses. riding a searchllght type of ray or beam. To visualize this. let's take a spotlight and stand at the back of a "drive-in" theatre. Now, if we take the light and start at the upper left hand cor- nor of the screen, and flash the light across to the right side, we have "scanned" the screen. Moving the light beam down a few inches we now go from right to left across the screen. Again we have scanned the screei. with the light. Now we take the light and put it on a mechanical device which whips the light back and forth of at a tremendous speed, moving down a few inches each time it goes across. We turn the machine on and the result to our eyes is that the whole screen is brightly llzhted. and-arrow tang is Luv i....-i"y'.li. no "W 52 and broad A's are n.'i:: like.

A 35.11 light or scanning beam is mount- ed at the back of your tube. it whips back and forth at a tre- mcndous speed across the screen, and each time it crosses. it moves down a fraction.
