Trade and manufactures were the great interests of the age, and they were represented by the men of the commons, whose minds were entirely occupied by such matters, and whose desire was to benefit them, as they thought, by making laws for their regulation. They had not learnt the great lesson, that trade prospers best when it is left alone by law-makers. They were inexperienced in making laws, and charmed with their new power, thought it would be easy to make the world go rightly by making laws about everything. Continually the laws when made were found to have quite different results to what the law-makers had expected, and had to be repealed the next year. This restless desire to interfere in everything was very harmful to trade and industry. There were so many changes that people found it difficult to know what the law really was. Many of the laws were not attended to at all, as it was impossible to watch over the people narrowly enough to see that they were obeyed. We have seen how Parliament tried to fix the price of labour. In the same way it tried to fix the price of everything else. It fixed the price at which tailors should make clothes, at which poultry, meat, bread, and all other articles of ordinary consumption were to be sold. Even the number of dishes which a man might have for dinner was fixed by law. These laws have left no permanent impression on English history, and are interesting only as giving indications of the manners and customs of the times. They serve also to show how greatly the energy of Parliament increased in this reign, even though it was misdirected. There are other and more important things which show us the great increase of its power. It had always been the theory of the English Constitution, that the King could not raise money without the consent of the Great Council of the Realm; but this had often been little more than a theory. In this reign it became a clearly recognized fact, that no money could be raised except with the consent of Parliament, and we find Edward III. always appealing to Parliament in his necessities. Parliament also established its right to petition against grievances, and so insisted upon the necessity of both Houses agreeing before any change could be made in the laws. Edward III. held frequent Parliaments, and made it his practice to consult them on all matters, even on what had been always supposed to belong entirely to the King, the making of war and peace. He seemed to wish to throw upon Parliament the responsibility of his expensive wars. Probably he hoped that if the war was ostensibly carried on by the advice of Parliament, it would be easier to obtain grants of money for its expenses. The Commons, however, were not very eager to advise on these difficult points, saying that they were too simple and ignorant to be able to do so, and promising to agree to anything which the King and his council might decide upon.
