Court officials also include the various nobles in charge of the royal palaces, castles, and hunting lodges at Potsdam, Charlottenburg, Breslau, Stettin, Marienburg, Posen, Letzlingen, Hohkönigsberg, Homberg von der Höhe, Springe, Hubertusstock, Rominten, Korfu (the "Achilleion"), Wiesbaden, Koenigsberg, etc., to the number of thirty or more. The Empress has her own Court officials, including a Mistress of the Robes and Ladies of the Bedchamber, also with the title of Excellency, the Ladies being chosen from the most aristocratic families of Germany. The Empress has her own Master of the Household, physician, treasurer, and so on. Similarly with the households of the Crown Prince, other royal princes and the Emperor's near relatives. Every order the Emperor gives that is not of a purely domestic kind passes through one of his three cabinets--the Civil Cabinet, the Military Cabinet, or the Marine Cabinet. The cost of the first, with its chief, who receives £1,000 a year, and half a dozen subordinate officials on salaries of £200 to £350, is budgeted at about £10,000 a year. The Military Cabinet is a much larger establishment, having several departments and a staff of half a hundred councillors and clerks. The Naval Cabinet, on the other hand, is composed of only three upper officials and five clerks. The Emperor's "civil list" is returned in the Budget as £860,000 roughly. His entire annual revenue does not exceed £1,000,000. Out of this he has to pay the expenses of his married sons' households and make large contributions to public charities. He was left, however, a very considerable sum of money by the Emperor William. The Crown Prince, as such, receives a grant of £20,000 a year, chiefly derived from the royal domain of Oels in Silesia. Like all fathers of large families, the Emperor has been more than once heard to complain that he finds it difficult to make both ends meet.
