For, while making every allowance for the evil effects of education, wrongly conceived and improperly administered, on the character of women destined to become servants, it must be allowed that much of what we call the servant difficulty could be cured now, and will unquestionably be cured before long, by inventions capable of abolishing the grievances which lead to it. These grievances are real and remediable. I do not refer to the confinement, restraint and gross lack of consideration on the part of employers which lead young women of the class from which servants are drawn to prefer labour in factories and elsewhere, in conditions far less comfortable, before domestic service; but to our utter lack of ingenuity in removing the irksomeness and degradation of much domestic labour. Some coming inventions calculated to improve the lot of Mary Jane will now be described. In the first place (as Mr H. G. Wells has pointed out, without apparently being aware that buildings already exist in which some of his ideas have been anticipated), modern rooms, equally with those of all time, seem to have been constructed so as to make it as difficult as possible to keep them clean. Square corners and rectangular junctions of wall and floor, wall and ceiling, will certainly before long be replaced everywhere by curves. But the work of house cleaning will be rendered easy and unlaborious by another invention, already indeed in existence on a large scale, but eventually capable of being rendered portable. I mean a contrivance for applying a vacuum to any desired spot. There is a very ingenious but rather noisy engine already in use for pumping the dust out of carpets, curtains and furniture. In the houses of the future handy contrivances of various shapes, all independent of any engine, will be found, furnished with elastic nozzles on the outside and with some sort of appliance capable of instantly exhausting the air within. Such a utensil wheeled over the floor will remove instantly every particle of dust from the surface and below the surface of the carpet, at the same time picking up any such débris as scraps of paper, pins, and other decidua of the previous day. A similar instrument, differently shaped, will clean the curtains, supposing curtains to be still in use at the time, and will dust the chairs and tables--though there will not be anything like so much dust as there is now, nearly all kinds of combustion being abolished. The kitchen fire will of course be an electric furnace: "o' my word we'll not carry coals." Lighting will all be electric, and no doubt wireless. The abolition of horse traffic in cities, and the use of the vacuum apparatus which will be continuously at work in all streets, keeping them dry and free from mud, will practically remove the necessity for boot brushing, even supposing that we shall still wear boots: every man and woman in dressing will pass a vacuum
