[56] "The House of Commons is called the Lower House in twenty Acts of Parliament," says Selden. "But what are twenty Acts of Parliament amongst friends?"--"Table Talk," p. 36. The power of the Commons increased gradually as time advanced. By the end of the thirteenth century they had secured sufficient authority to ensure that no tax could be imposed without their consent. By the middle of the fourteenth no law could be passed unless they approved. But many centuries were yet to elapse before the chief government of the country passed into their hands. The expense of sending representatives to Parliament was long considered a burden, many counties and boroughs applying to be discharged from the exercise of so costly a privilege. The electors of those days were apparently less anxious to furnish a Member for the popular assembly than to save the payment of his salary. Indeed, the city of Rochester, in 1411, practised the frugal custom of compelling any stranger who settled within its gates to serve a term in Parliament at his own expense. He was thus permitted to earn his freedom, and the parsimonious citizens saved an annual expenditure of about £9.[57] [57] "Quarterly Review," vol. xxix. p. 63. With the gradual growth of parliamentary power the importance of electing members to the House of Commons began to be recognized, and, during the Wars of the Roses, fewer and fewer applications were made by boroughs and cities anxious to be relieved of this duty. Until Henry VI.'s time, when the modern system of Bills and Statutes began to come into being, legislation was by Petition. The control of Parliament was still very largely in the hands of the Crown, and successive sovereigns took care that their influence over the Commons should be maintained. With this object in view Edward VI. enfranchised some two-and-twenty rotten boroughs, Mary added fourteen more, and in Elizabeth's time sixty-two further members, all under the royal control, were sent to leaven the Commons. The attendance in the Lower House was still poor, not more than two hundred members ever taking part in the largest divisions, and it was only at the culmination of the conflicts between Parliament and the Stuart Kings that the Commons began to display a real desire for independent power.
