end of the long journey from eastern factories near the final resting place of these people circus is to be the floor of san francisco bay in fact these are the actual circuits that were planned to serve the artificial island that was made to rise from the historic waters as a home for the golden gate international exposition and after serving the crowd strong this appealing panorama of foreign and domestic attractions the same circuit will be part of a grea will join the others already winding beneath the surface of the bay to bring the voice of america to this busy port on our western shore there's an interesting engineering story in the sequence of pictures what i see in them another in a special single drop what if one dropped another socket another and another and another until the electrical transmission of speech is impossible under water circuits must be provided by the cable makers with unusual protection both against the camera lens gives us a close look at this protection as it pictures two cable length being spliced together the splashing job itself is no small task the engineers anticipated the needs of the coming years and  pressure per square inch is forced through the hole to surround the wires just spliced and then an extremely unromantic substance comes into use plain everyday soap suds but the soap suds are most affected here or finally about two miles of armor cable is coil on the big drum ready for its underwater resting place on the floor of the big one of the piers the bay bridge that stretches more than eight miles over land or water to link san francisco and oakland is the midway point for uniting to long that's just what it is an oversized but not of the kind popularized with that famous a languorous it was in this particular poll is in reality a radio antenna that will fish telephone messages out of the air and it will of the operators might be in such emergencies as when a hurricane or a flood resemble has brought about a gap in the wire facilities since communications such times is all important the engineer set out to develop this radio bridge which combined radio transmitter and receiver of special design that needs only simple adjustments to be ready for service a third unit for switching and general control completes the compact than portable out that in a few minutes after reaching a locality where service has been interrupted the antenna is in place and connections made with the telephone wires at the point of the break and then station well let's call it station p h o n e  ready to go on the air ready to communicate with a similar unit that is waiting for messages across a flooded ballet a storm swept mountain range or in some suddenly isolated community or perhaps at an emergency relief station such as a indeed here are seen reminding us again that the place to learn about the interest of the people is where they gather in large and revealing numbers for anyone curious about our national interest the essence our pleasures not relaxations the obvious unwise procedure is to go following this crowd it's a telephone company experimenting with a equip a telephone booth that can be towed far out in the country where people may assemble for a few hours and then disappear here it comes with car close behind so that the trailer can quickly be connected to the nearby wire after that is done and with miss maryland presiding it's already for those who may have need for a convenient
