However it seems I was a it to hasty to declare the book to be in Public Domain already. At least one of the named authors, William Armstrong (W.A.) Graham lived till 1949, so it will take till 2020 that the 70 years after his death are reached. But quoting this section, which has no named author and was probably written by the editor Cecil Carter himself, should no be any problem.
The administration of the country was formerly divided between the three Ministers, the Minister for Civil Affairs and the Minister for Military Affairs, with the Minister of the Treasury as Governor-General.
But in 1894 the internal administration was reorganized and the whole of the country placed under the administration of the Ministry of the Interior (Mahathai) with the exception of the capital and surrounding provinces, which is administered by the Ministry of Local Government.
At the head of the Interior Administration is the Minister appointed by the King with a seat in the Cabinet; he is assisted by a Vice-Minister, who, however, holds no seat in the Cabinet.
The ancient provinces, whilst retaining their boundaries, are now grouped together into Monthons or Circles under High Commissioners, who are appointed by the King, but act under the orders of the Ministry of the Interior.
