Besides the departments subordinate to the Treasury, there are a number of outlying departments more or less closely connected with it which have already been referred to as having nothing to do with financial affairs; and, indeed, one may say that in theory, at least, every branch of the public service--except the Ecclesiastical and Charity Commissions[129:2]--that does not have a political chief of its own, and is not connected with some other department, is under the supervision of the Treasury and represented in Parliament thereby. But while the commissioners, or other heads of such offices, are as a rule appointed on the recommendation of the First Lord, or of the Prime Minister, the degree of control exercised over them by the Treasury varies a great deal; and in some cases its responsibility, apart from regulating the amount of expenditure, is somewhat illusory. Several institutions in this position are intended to be entirely outside the range of party controversy; and the boards of trustees of the British Museum, the National Gallery, and the National Portrait Gallery habitually contain members of Parliament who would never think of resigning their posts by reason of a change of ministry. The principal outlying departments of the Treasury directly connected with national administration, are: the Civil Service Commission, which examines the candidates for the various branches of the civil service; the Parliamentary Counsel's office, which drafts all the bills introduced by the ministers; and the stationery office, which does all the government printing.
