Some ladies were patrons of writers. Some women were active in prison reform in matters of reviews to insure that no man was in gaol without due cause, overcharges for bed and board, brutality, and regulation of prisoners being placed in irons. Many men and women left money in their wills for food and clothing for prisoners, especially debtors. Wills often left one-third of the wealth to the church, the poor, prisoners, infirmaries, young girls' education; road, wall, and bridge repair; water supply, markets and almshouses. Some infirmaries were for the insane, who were generally thought to be possessed by the devil or demons. Their treatment was usually by scourging the demons out of their body by flogging. If this didn't work, torture could be used to drive the demons from the body. The guilds were being replaced by associations for the investment of capital. In associations, journeymen were losing their chance of rising to be a master. Competition among associations was starting to supplant custom as the mainspring of trade. The cloth exporters, who were mostly mercers, were unregulated and banded together for mutual support and protection under the name of Merchant Adventurers of London. The Merchant Adventurers was chartered in 1407. It was the first and a prototype of regulated companies. That is the company regulated the trade. Each merchant could ship on his own a certain number of cloths each year, the number depending on the length of his membership in the company. He could sell them himself or by his factor at the place where the company had privileges of market. Strict rules governed the conduct of each member. He was to make sales only at certain hours on specified days. All disagreements were to be settled by the company's governor, or his deputy in residence, and those officials dealt with such disputes as arose between members of the company and continental officials and buyers. A share in the ownership of one of their vessels was a common form of investment by prosperous merchants. By 1450, the merchant adventurers were dealing in linen cloths, buckrams [a stiffened, coarse cloth], fustians [coarse cloth made of cotton threads going in one direction and linen threads the other], satins, jewels, fine woolen and linen wares, threads, potions, wood, oil, wine, salt, copper, and iron. They began to replace trade by alien traders. The history of the "Merchant Adventurers" was associated with the growth of the mercantile system for more than 300 years. It eventually replaced the staples system.
