I visited the place of recreation, a neat plain rotunda, in the centre of an extensive flower garden, where the young people, the middle aged, and the old occasionally convened, to extend their knowledge of one another, interchange their thoughts by conversation, listen to the most exquisite music, and practise a variety of graceful and elegant exercises. Being all very fond of music, they all join in that, by turns, as in other performances. Sometimes an hundred instruments, and many hundreds of the most exquisite voices, filled the whole place with the most enchanting sounds. The exquisite beauty of the women, the graceful dignity of the men, the chaste decorum and sincere politeness of all, charmed the mind, and delighted the heart. Here there were no temptations to vice by offers of seducing cordials, wines, agreeable decoctions, or other intoxicating drinks, as in our places of resort for recreation. The enjoyments of this refined people were intellectual and pure--not the debasing gratifications of animal passions and sensual appetites. The soft reflected light of the sun, which was now no longer directly visible, gave a pleasing mellowness to the scene, that was inexpressibly agreeable, being about midway between a bright moonlight and clear sunshine. I had great cause to admire the wonderful provision of nature, by which the internal world enjoyed almost perpetual light, without being subject at any time to the scorching heats which oppress the bodies and irritate the passions of the inhabitants of the external surface. When the sun has great southern declination, it is seen directly through the opening at the south pole, a little above the horizon--this gives an interval of bright light; and as the rays of heat are more refrangible than those of light [4], a sufficient degree of heat is experienced to ripen the most delicate fruits. At this season, during night, the rays of the sun are reflected from the opposite rim of the polar opening, and afford so much light as to render the stars invisible. The full moon is never seen at this period; for while the sun is in south declination, the moon fulls to the north of the equator, to give light to the north polar region, and the northern internal hemisphere. March and September are the darkest months. Both the sun and full moon are then in the equator, and shine very obliquely by refraction, into both polar openings. Yet, by reflection from side to side, they afford a faint light quite to the internal equator, where two reflected suns and moons are dimly seen at the same time. This circumstance had led the internals to suppose that there were actually duplicates of those luminaries. Their situation, it should be considered, did not admit of such observations of the celestial bodies, as were necessary to correct that error.
