_Bill for septennial parliaments._--Upon this prevalent disaffection, and the general dangers of the established government, was founded that measure so frequently arraigned in later times, the substitution of septennial for triennial parliaments. The ministry deemed it too perilous for their master, certainly for themselves, to encounter a general election in 1717; but the arguments adduced for the alteration, as it was meant to be permanent, were drawn from its permanent expediency. Nothing can be more extravagant than what is sometimes confidently pretended by the ignorant, that the legislature exceeded its rights by this enactment; or, if that cannot legally be advanced, that it at least violated the trust of the people, and broke in upon the ancient constitution. The law for triennial parliaments was of little more than twenty years' continuance. It was an experiment which, as was argued, had proved unsuccessful; it was subject, like every other law, to be repealed entirely, or to be modified at discretion. As a question of constitutional expediency, the septennial bill was doubtless open at the time to one serious objection. Every one admitted that a parliament subsisting indefinitely during a king's life, but exposed at all times to be dissolved at his pleasure, would become far too little independent of the people, and far too much so upon the Crown. But, if the period of its continuance should thus be extended from three to seven years, the natural course of encroachment, or some momentous circumstances like the present, might lead to fresh prolongations, and gradually to an entire repeal of what had been thought so important a safeguard of its purity. Time has happily put an end to apprehensions which are not on that account to be reckoned unreasonable.[343]
