The conventions of the constitution have limited and regulated the exercise of all legal powers by the regular organs of the state in such a way as to vest the main authority of the central government--the driving and the steering force--in the hands of a body entirely unknown to the law. The members of the cabinet are now always the holders of public offices created by law; but their possession of those offices by no means determines their activity as members of the cabinet. They have, indeed, two functions. Individually, as officials, they do the executive work of the state and administer its departments; collectively they direct the general policy of the government, and this they do irrespective of their individual authority as officials. Their several administrative duties, and their collective functions are quite distinct; and may, in the case of a particular person, have little or no connection. The Lord Privy Seal, for example, has no administrative duties whatever; and it is conceivable that the work of other members might not come before the cabinet during the whole life of the ministry. [Sidenote: Functions of the Cabinet.] The essential function of the cabinet is to coördinate and guide the political action of the different branches of the government, and thus create a consistent policy. Bagehot called it a hyphen that joins, a buckle that fastens, the executive and legislative together; and in another place he speaks of it as a committee of Parliament chosen to rule the nation. More strictly, it is a committee of the party that has a majority in the House of Commons. The minority are not represented upon it; and in this it differs from every other parliamentary committee. The distinction is so obvious to us to-day, we are so accustomed to government by party wherever popular institutions prevail, that we are apt to forget the importance of the fact. Party government as a system has developed comparatively recently; but it has now become almost universal. The only exception among democratic countries (that is, the only case where the executive body habitually contains members of opposing parties) is in Switzerland. Still the system is carried to a greater extent in some countries than in others; and the amount of power concentrated in the hands of a single party leader, or a body of party leaders, varies very much. The President of the United States, for example, is the representative of a party; but he rules the nation only in part. The legislature is neither in theory or in practice under his control; and this is so far true that even when Congress is of the same party as himself, neither he nor any committee of the party so controls both executive and legislative that any one body can be said to rule the nation. But where the parliamentary system prevails, the cabinet, virtually combining in its own hands, as it does, the legislative and executive authorities, may fairly be said to rule
