Domestic scientific advances (1887)

Science in the house

HourglassScience, in a mild form, is now occupying itself in making many inventions for domestic purposes, saving time and trouble to the housekeeper.

Among the latest are striking sandglasses to be used by the cook, or another, in operations which require a specified amount of time and attention. One of these glasses is so weighted and hung that the emptying of the sand reverses it and causes a metal attachment to strike against the stand in falling, thus giving a note of warning, so that the person using it is able to attend to other things meanwhile, instead of having, as formerly, to give unceasing glances at the running of the sand. This little implement everybody who has ever boiled an egg or done any other brief thing of the kind, by the help of a three-minute glass, will feel to be a great enfranchisement.

Another invention useful to those who keep birds, is a cage, on one side of the floor of which is fitted a roll of thick water-proof paper, running through grooves and crossing the entire bottom of the cage. Every morning, the soiled paper is pulled through and torn off in its own crease without more ado, ready to be thrown in the fire; and the fresh paper, in the act of pulling off the soiled, has taken its place, thus sparing the person whose duty it is to attend to the cleanliness of the cage much trouble and annoyance, and the little tenant of the place much fluttering.
