A Dial System Speaks for Itself As dial systems have been improved, so also have the means of keeping them at top efficiency. Even before trouble appears, test frames, developed in Bell Telephone Laboratories, are constantly at work send- ing trial calls along the telephone high- ways. Flashing lamps report anything that has gone wrong, and the fault is quickly located and cleared.
If trouble prevents one of the highways from completing your call, another is
selected at once so that your call can go through without delay. Then on the test frames lights flash up telling which high- way was defective and on what section of that highway the trouble occurred.
Whenever Bell Laboratories designs a new telephone system, plans are made for its maintenance, test equipment is de- signed, and key personnel trained. Thus foresight keeps your Bell telephone system in apple-pie order.

Steel would be more durable, but our care- ful checking over the years proves that lab- oratory animals breed better, maintain better health in wooden cages.
These cages are hung from the ceiling-do not touch the floor-to minimize insect in- festation. This is another example of the care that produces dependable uniformity in the CF strains of mice, rats, and guinea pigs, and explains why they are the choice of so many leading research laboratories.

Great drama comes to television in NBC telecasts of Theatre Guild presentati,
AHow wide is "Broadway"?
To all the world "Broadway" means the theatre. So when NBC, in October, 1947, introduced regu- lar telecasts of Theatre Guild pro- ductions, an expansion of "Broad-
way" began-and some day it will be nation-wide.
Today, if you live in a television area almost anywhere from Boston to Richmond, the new "Broadway" of television runs past your door. Now you can see great plays, pro-
fessionally performed by noted actors. That's news, exciting news, to lovers of the theatre.
Celebrated artists run through lines and action before keen-eyed RCA Image Orthicon television cameras. At your end of the pic- ture, on an RCA Victor home tele- vision receiver, action is sharp, clear, detailed . . . and voices flawless.
That television can make so im-
portant a contribution to Ameri entertainment is in good part result of pioneering and researcl RCA Laboratories. Such resez enters every instrument bearing name RCA or RCA Victor.
