Cleaning, rubbing the skin off your hands when washing and wringing linen; sweeping floors and brushing carpets, thereby raising clouds of dust which afterwards occasion much trouble to dislodge from the places where they have settled down, all this work is still done because woman remains a slave, but it tends to disappear as it can be infinitely better done by machinery. Machines of all kinds will be introduced into households, and the distribution of motor-power in private houses will enable people to work them without muscular effort. Such machines cost little to manufacture. If we still pay very much for them, it is because they are not in general use, and chiefly because an exorbitant tax is levied upon every machine by the gentlemen who wish to live in grand style and who have speculated on land, raw material, manufacture, sale, patents, and duties. But emancipation from domestic toil will not be brought about by small machines only. Households are emerging from their present state of isolation; they begin to associate with other households to do in common what they did separately. In fact, in the future we shall not have a brushing machine, a machine for washing up plates, a third for washing linen, and so on, in each house. To the future, on the contrary, belongs the common heating apparatus that sends heat into each room of a whole district and spares the lighting of fires. It is already so in a few American cities. A great central furnace supplies all houses and all rooms with hot water, which circulates in pipes; and to regulate the temperature you need only turn a tap. And should you care to have a blazing fire in any particular room you can light the gas specially supplied for heating purposes from a central reservoir. All the immense work of cleaning chimneys and keeping up fires--and woman knows what time it takes--is disappearing.
