Another reason for the homes of all officials of the Government being within the public buildings, was because all the personal expenses, excepting clothing, were paid by the Government. The salaries of Government positions were not large, compared with those of the sciences; but as their social and political dues were paid out of the public treasury, the salaries might be considered as net profit. This custom had originated many centuries in the past. In those early days, when a penurious character became an incumbent of public office, the social obligations belonging to it were often but niggardly requited. Sometimes business embarrassments and real necessity demanded economy; so, at last, the Government assumed all the expenses contingent upon every office, from the highest to the lowest. By this means the occupant of a Government office was freed from every care but those of state. The number and style of all social entertainments that were obligatory of the occupant of a public office, were regulated by law. As the people of Mizora believed in enjoyment, the entertainments provided by the Government as the necessary social dues of its officers, were not few, nor scantily furnished. CHAPTER XII. The artificial light in Mizora puzzled me longest to understand. When I first noticed it, it appeared to me to have no apparent source. At the touch of a delicate hand, it blazed forth like a star in the center of the ceiling. It diffused a soft and pleasing brilliancy that lent a charm to everything it revealed. It was a dreamy daylight, and was produced by electricity. In large halls, like a theatre or opera house, the light fell in a soft and penetrating radiance from the center of the dome. Its source was not visible to either audience or actresses, and, in consequence, occasioned no discomfort to the eyes. The light that illuminated the stage was similarly arranged. The footlights were not visible. They were in the rear of the stage. The light came upward like the rays of the setting sun, revealing the setting of the stage with vivid distinctness. I can best describe the effect of this singular arrangement by calling attention to the appearance of the sun when declining behind a small elevation. How sharply every object is outlined before it? How soft and delicate is the light in which everything is bathed? Every cloud that floats has all of its fleecy loveliness limned with a radiant clearness.
