Political checks will no more act of themselves than a bridle will direct a horse without a rider. If the checking functionaries are as corrupt or as negligent as those whom they ought to check, and if the public, the mainspring of the whole checking machinery, are too ignorant, too passive, or too careless and inattentive, to do their part, little benefit will be derived from the best administrative apparatus. Yet a good apparatus is always preferable to a bad.
