The streets have plenty of life and movement in them, but a minimum of rattling jarring noises, owing to the heavy traffic being conducted through the underground railways. Most of the principal factories are at a short distance from the city; as are also large clusters of workrooms let out singly. A workman can have a workroom on payment of a moderate weekly rent; in it he can work as many hours as he pleases, but must not make it his home. Each block is under the charge of a superintendent, and under the supervision of a sanitary inspector. The artisan goes away from his home to work, like the lawyer, the merchant, or the banker. There might appear to be some waste of time in this arrangement; but it is more than compensated, in the opinion of the citizens of Hygeia, by comparative immunity from disease: 'It has,' says Dr Richardson, 'been found in our towns generally, that men and women who are engaged in industrial callings, such as tailoring, shoe-making, dressmaking, lace-making, and the like, work at their own homes among their children. That this is a common cause of disease is well understood. I have myself seen the half-made riding-habit that was ultimately to clothe some wealthy damsel rejoicing in her morning ride, act as the coverlet of a poor tailor's child stricken with malignant scarlet fever. These things must be, in the ordinary course of events under our present bad system. In the model system we have in our mind's eye, these dangers are met by the simple provision of workmen's offices or workrooms.' Public laundries are a feature in Hygeia. If the washing of a small family is done at home, the housewife knows with what she has to deal; but when 'the washing is put out,' the linen of the family may, for aught she knows, have been mixed before, during, or after the process of washing with the linen from the bed or the body of some sufferer from a contagious malady. Some of the most fatal outbreaks of disease are known to have been communicated in this manner. To avoid these evils, public laundries are established in the outskirts of Hygeia, each with an extensive drying-ground, and all under sanitary inspection.
