2. Similarly also if we view the compositions in light of what we have described as the second of their objects. The excellent motive of mediaeval regulation of industry was to secure the prosperity of trade by ensuring skilled workmanship and proper materials. In consequence it was forbidden for workmen whose capacity was unknown to work in the town until their efficiency had been proved. The Barbers' composition of 1432 ordered that "no man' p'sone sette up nother holde no shoppe in Privite ny apperte ny shave as a Maistre withinne the saide Tow' ny Franchise in to the Tyme that ev'y such p'sone have the Wille and Assent of the Stywardes and Maistres of the saide Crafte." It was the desire to ensure the public being well served that prompted the articles in the composition of the Mercers (1480-1) which ordered the Searcher "to make serche uppon all the occupyers of the saide Craftes ... that non of theym occupie eny false Balaunce Weight or Mesures belongeing to the sayde Craftes or eny of theym, wherebie the Kyngs People in eny wyse myght be hurt or dysseyved." It was also part of the same officer's duties to "oversee that any thyng app'tenyng to the saide Craftes or eny of theym to be boght and solde in the saide Towne and Frauncheses be able suffyceant and lawfull and that noe dyssayte nor gyle to the Kyngs liege people therbye be had." No indentures were to be drawn for less than "seven years at the least," so that adequate training should be secured. We thus perceive how the Craft Gilds differed, on the one hand from the Frith Gilds of more ancient times, and on the other from the Commercial Companies of later days. The former were associations in which every member was responsible for the actions of each of his fellows; in the Craft Gilds each member bound himself to abide by the regulations of the rest. The essence of the later Commercial Companies is union for mere pecuniary gain; the Gilds set in the forefront of the objects of their association the material benefit of the community and the religious and moral good of the individual. The resemblance between Trades Unions and the Mediaeval Gilds is not entirely fanciful; but no two documents can be more widely different than the Prospectus of a Limited Liability Company and a Gild Charter of the Middle Ages.
