It is evident why public debate is the very breath of life to such a system. The Ministry's tenure of office depends upon the success of the legislation they urge. If any of their proposals are negatived by parliament, they are bound to accept their defeat as an intimation that their administration is no longer acceptable to the party they represent, and are expected to resign, or to appeal, if they prefer, to the country for its verdict, by exercising their privilege of advising the sovereign to dissolve parliament and issue writs for a new election. It is, consequently, inevitable that the Ministry should be subjected to the most determined attacks and the keenest criticisms of the Opposition, and should be every day of the session put to the task of vindicating their course and establishing anew their claim to the confidence of their party. To shrink from discussion would be to confess weakness; to suffer themselves to be worsted in discussion would be seriously to imperil their power. They must look to it, therefore, not only that their policy be defensible, but that it be valiantly defended also. As might be expected, then, the Ministry seldom find the task of leading the House an easy one. Their plans are kept under an unceasing fire of criticism from both sides of the House; for there are independent sharp-shooters behind the ministers as well as heavy batteries in front of them; and there are many amongst their professed followers who give aid and comfort to the enemy. There come ever and again showers of stinging questions, too, from friends and foes alike,--questions great and small, direct and indirect, pertinent and impertinent, concerning every detail of administration and every tendency of policy.
