Later, when it was all over, they went down to the street floor at Ralph's suggestion, where they put on their Tele-motor-coasters, preparatory to seeing more of New York—this time by night.
The party proceeded to roll down Broadway, the historic thoroughfare of New York. Despite the fact that it was 11 o'clock at night, the streets were almost as light as at noonday. They were illuminated brilliantly by the iridium spirals, hanging high above the crossings. These spirals gave forth a pure, dazzling-white light of the same quality as sunlight. This light moreover was absolutely cold, as all electrical energy was transformed into light, none being lost in heat. Not a street was dark—not even the smallest alley.
James 212B 422, as well as his daughter, lingered over the superb displays in the various stores and they entered several to make a few purchases. Alice was much impressed with the automatic-electric packing machines.
The clerk making the sale placed the purchased articles on a metal platform. He then pushed several buttons on a small switchboard, which operated the "size" apparatus to obtain the dimensions of the package. After the last button was pressed, the platform rose about two feet, till it disappeared into a large metal, box-like contrivance. In about ten to fifteen seconds it came down again bearing on its surface a neat white box with a handle at the top, all in one piece. The box was not fastened with any strings or tape, but was folded in an ingenious manner so that it could not open of its own accord. Moreover, it was made of Alohydrolium, which is the lightest of all metals, being one-eighth the weight of aluminum.
The automatic packing machine could pack anything from a small package a few inches square up to a box two feet high by three feet long. It made the box to suit the size of the final package, placed the articles together, packed them into the box which was not yet finished, folded the box after the handle had been stamped out, stenciled the firm's name on two sides and delivered it completely packed, all within ten to fifteen seconds.
The box could either be taken by the purchaser or the clerk would stencil the customer's name and address into the handle, place a triangular packet-post stamp on the box and drop it into a chute beside the counter. It was carried down into the Packet-Post Conveyor, which was from seventy-five to one hundred feet below the level of the street, where it landed on a belt-like arrangement moving at the rate of five miles an hour. The action was entirely automatic and the chute was arranged with an automatic shutter which would only open when there was no package immediately below on the moving belt. This precluded the possibility of packages tumbling on top of each other and in this way blocking the conveyor tube.
When the package had landed on the conveyor belt it traveled to the nearest distributor office, where the post office clerk would take it from the belt and see if it was franked correctly. The stamp was then machine cancelled and after the clerk had noted the address he routed it to the sub-station nearest to the addressee's home. Next he clamped onto the package an automatic metal "rider" which was of a certain height, irrespective of the size of the package.
The package with its rider was placed on an express conveyor belt traveling at the rate of 25 miles an hour. This express belt, bearing the package, moved at an even speed, and never stopping, passed numerous sub-stations on the way. At the correct sub-station the rider came against a contact device stretching across the belt at right angles, at a certain height. This contact arrangement closed the circuit of a powerful electromagnet placed in the same line with the contact, a few feet away from the express belt. The electromagnet acted immediately on the metal package (Alohydrolium is a magnetic metal), drawing it in a flash into the sub-station from the belt. If there was another package right behind the one so drawn out, it was handled in the same manner.
After the package had arrived at the sub-station it was despatched to its final destination. Another rider was attached to it and the package placed on a local conveyor belt passing by the house to which it was addressed. On arriving at the correct address its rider would strike the contact overhead, which operated the electromagnet, pulling the package into the basement of the house, where it fell on the platform of an electric dumb-waiter. The dumb-waiter started upward automatically and the package was delivered at once.
