(4) A less appalling, but still sufficiently serious; aspect of industrial unrighteousness is the dirty, crowded, ugly, unsanitary, and sometimes indecent conditions under which many workers in our prosperous age have to carry on their work. Lack of proper lighting, space, and ventilation, unnecessary noises, and general untidiness, undermine the health and morals of laborers; while insufficient fire- protection causes intermittently one tragedy after another. Much has been done in many quarters to improve such conditions; not a few up-to- date factories are models of cleanliness and sanitation, spacious, reasonably quiet, and altogether pleasant places in which to spend the working day. They point the way which all must in time follow. In addition, the provision of reading-rooms, baths, rest- and recreation- rooms, lunch-rooms, athletic fields, and the like, give augury of that happy future when work shall be divorced from ugliness and free from unnecessary physical strain.[Footnote: Sir T.

Well over a hundred thousand men, women, and children are killed or injured every year in the various industries of this country. Our proportion of accidents is far greater than in Europe; the great majority are preventable by the adoption of known safeguards. What stands in the way is, partly, ignorance and heedlessness on the part of employers, and, still more, the initial cost of installing safety appliances. It is often cheaper to lose an occasional damage suit than to forestall accidents. In coal mines alone we have let thirty thousand men be killed and seventy-five thousand be more or less seriously maimed, in a decade; proportionately about twice as many as in European mines-which are far from ideally safeguarded. There are two ways to check this waste and crippling of human life; one is to keep our legislation up to date, and require the installation of every effective safety device, no matter if the cost to the public has to be increased. The other is to make accidents so expensive to employers that they will have a greater interest in taking measures to prevent them.
