In the matter of cloth and clothing, wool and flax are grown both by individuals and by the community, and the spinning and weaving are done in the town mills. These are built and equipped at the common charge and managed by officials who serve for fixed salaries. A certain percentage on the value of all raw material brought in for working up into the finished product is assessed on the owner, and this may be paid in cash or in kind. No raw material is ever acquired from outside the community; all internal surplus is purchased and made up into cloth, which is sold first to any townspeople who wish to buy, or second to outside purchasers, the profits going to defray the running expenses. As a matter of fact, there is always a large surplus of wool and flax over and above the normal needs of each producer, and the mills not only run at a profit but pay well on the original investment. In these mills highly perfected machinery is used, for while the Walled Towns were formed partly for the elimination, so far as possible, of machines in the affairs of life, it is realized that they may be used as actual labour-savers, and without serious injury to the workman, where they are employed on bulk-production such as cloth, and where the element of competition is eliminated. Since in manufacture of this kind division of labour is unavoidable and the work is mechanical and akin to drudgery, the wages paid are high, while the hours of employment never exceed thirty a week. Practically all the employees are able to take care of their own gardens and many have small farms as well. During the seed-time and harvest periods the mills are shut down. When it happens (as it often does) that a mill shows a profit, all in excess of three per cent on the value of the plant is divided between the employees and the clerical force, for one of the established laws of all Walled Towns is that capital is entitled only to a fixed return, the surplus belonging to the labour, both mental and physical, that produces the results. Stock companies as such are strictly prohibited and it is unlawful to pay money for the use of money furnished by inactive investors. The mills are of course not large; they are pleasantly situated, not without architectural quality, and they are always run either by water-power or by electricity hydraulically generated. Steam is not used in any case.
