Much has been invented, but there are yet a host of gadgets which would prove a boon and a blessing to suffering humanity. To take a few. There is a fortune awaiting the inventor of the non-skid eiderdown and the double-ended blanket which will cover the neck and the feet simultaneously. The boomerang collar stud is a crying necessity. It would not only reduce the danger of paternal blood pressure, but greatly improve the moral tone of the house. Some further suggestions are the automatically self-filling bottle, the folding motor-car for parking under the office table, the homing umbrella, the mating socks, the un-breakable rubber alarm clock which can be hurled across the bedroom without suffering injury, the mechanical office boy, the square egg, the skid-proof pea, the silent soup-spoon, the jumping hat which will spring on its owner even after a smoke concert; the squirtless grapefruit, the skidless soap, the soundless saxophone, barnacle buttons for trousers, the self-filling bank account, the climbing train ticket which will clamber out of its hiding place when called, the radio-directed lawn-mower worked from a deck-chair by buttons, ingrowing whiskers which can be bitten off to save shaving, self-latching evening collars that don't need a locksmith to get on and off, and self-starting typewriters in which to insert a sheet of paper at night and unship a completed article in the morning.
