Besides the appointment of his colleagues, the Prime Minister also has in his patronage a number of posts in the Royal Household, which become vacant when an Administration changes. These are not so difficult to fill, and are usually distributed among members of the House of Lords, who are thus bound to their party by ties even stronger than those of sentiment.[148] [148] Among the offices in the Royal Household which are filled by the Prime Minister, the most important are those of the Master of the Horse, the Lord Steward, the Lord Chamberlain, the seven Lords in Waiting, and the Mistress of the Robes. The actual Ministry consists of over forty persons, of whom perhaps a quarter form the Cabinet.[149] The annual cost to the country in ministerial salaries is well under £200,000, and cannot therefore be considered excessive, considering the delicacy of the administrative machine, the efficiency with which it is run, and the amount of work that has to be accomplished. [149] A complete list of the salaries and offices of Ministers does not lie within the scope of this volume. It will be sufficient to enumerate briefly the most important members of the administration. First in order of precedence stand the Prime Minister, the Lord High Chancellor, the Lord President of the Council, the Lord Privy Seal (an office to which, like that of the Prime Minister, no salary is attached), and the First Lords of the Treasury and Admiralty. After these come the five Secretaries of State: for Home Affairs, Foreign Affairs, the Colonies, War, and India. These are followed by the Chancellor of the Exchequer, the Secretaries for Scotland and Ireland, the Postmaster-General, the Presidents of the Board of Trade, Local Government Board, Board of Agriculture, and Board of Education, the Chancellor of the Duchy of Lancaster, and the First Commissioner of Works. There are, besides, eight Parliamentary Under-Secretaries, four Junior Lords of the Treasury (one of whom is unpaid), a Patronage Secretary, a Financial Secretary, a Paymaster-General, Attorney-General, and Solicitor-General. Scotland is represented by a Lord-Advocate and a Scottish Solicitor-General; Ireland by a Lord-Lieutenant, a Lord Chancellor, an Attorney-General, and a Solicitor-General.
