By DAVID SARNOFF PRESIDENT, RADIO CORPORATION OF AMERICA A twinkling beam of light records a picture thousands of miles away. It is facsimile transmission- an interesting feature of this authoritative article on the future developments of radio and television. IN HIS struggle for new information, man has been reaching farther and farther into mysteries beyond his accustomed sphere; farther with the runner through the forest . . . farther with camel caravans across trackless plains . . . farther with ships into uncharted oceans . . . seeking speed, and relishing the advantages of new contacts.

COUNTLESS inventors have rolled up tremendous fortunes by the development of new and simple toys as the several hundred manufacturers in this industry are ever in need of fresh attractions. Indeed, at the present time, there is an urgent cry for new material, and consequently we shall devote this month's department to an outline of some of the more pressing problems. Toys can be developed by any man without an elaborate work shop since most of them are made of bits of wood and cardboard.

by CHARLES W. GEIGER A comprehensive article on the Golden Gate and San Francisco Oakland Bay bridges, telling of man's struggle with nature to complete, at a tremendous cost, two of the most daring construction feats ever undertaken by American engineers. HIGH over the surging tides of San Francisco's Golden Gate, the two towers of the world's largest single suspension bridge stand in defiant majesty as symbols of man's victory over natural forces. And farther back, the eight mile skeleton of towers and piers stretch across the San Franciscoâ€”-Oakland bay, ready for the spans which will complete this, the world's most costly bridge project. These bridges, built at a total cost of $112,000,000, are being erected to aid traffic in and around San Francisco. The bridge to Oakland cuts the 30 mile trek around the circuitous shoreline of the bay to a straight 8-1/4 mile trip across the bridge; the Golden Gate project eliminates a detour of approximately 80 miles for direct coastal traffic between Canada and Mexico.
