Ever since England began to extend her dominion beyond the seas her foreign relations have been complicated by her distant possessions, and it is therefore natural to pass from the offices of the Secretary of State for Foreign Affairs on one side of the doorway in Downing Street to those of the Secretary of State for the Colonies on the other. But it is needless to speak of the Colonial Office at length here, because the government of the dependencies will form the subject of later chapters. The Secretary of State for the Colonies is assisted by his parliamentary and permanent under-secretaries, and by a staff of subordinate officials. There are in this office four permanent assistant under-secretaries; one of whom has charge of questions of law, and also at present of business connected with Canada, Australasia and a number of islands; another of South Africa; a third of the East and West Indies, emigration, prisons and hospitals, with a mass of miscellaneous matters; and the fourth of East and West Africa.[88:2] But the division of the colonies among these officers is not fixed, and varies to some extent with their personal experience. There are, in close connection with the office, agents for each of the dependencies, those for the self-governing colonies being real representatives appointed by the colonial governments, while the three who act on behalf of the crown colonies are selected by the Colonial Office itself. It may be observed that the Colonial Office has by no means charge of all the outlying dependencies of the British Crown. Besides the protectorates governed by the Foreign Office, there are a number of smaller places under the care of other departments. The Isle of Man and the Channel Islands, for example, are under the Home Secretary; some small islets are used only for lighthouses by the Board of Trade; while by an official fiction the Island of Ascension is considered a vessel of war, and as such is commanded by the Admiralty. But larger by far than any of these, more populous than all the other parts of the British Empire put together, is India. It is not classed among the colonies, for that term is confined to the places under the Colonial Office, and does not extend to a country ruled by a distinct administrative system of its own.
