I inquired how it was turned to reverse its progress so as to clean the whole floor, and was told to watch when it struck the wall. I did so, and saw that the jar not only reversed the machine, but caused it to spring to the right about two feet, which was its width, and again begin work on a new line, to be again reversed in the same manner when it struck the opposite wall. Carpeted floors were swept by a similar contrivance. No wonder the "artists" of the kitchen had such a dainty appearance. They dipped their pretty hands in perfumed water and dried them on the finest and whitest damask, while machinery did the coarse work. Mizora, I discovered, was a land of brain workers. In every vocation of life machinery was called upon to perform the arduous physical labor. The whole domestic department was a marvel of ingenious mechanical contrivances. Dishwashing, scouring and cleaning of every description were done by machinery. The Preceptress told me that it was the result of enlightenment, and it would become the custom in my country to make machinery perform the laborious work when they learned the value of universal and advanced knowledge. I observed that the most exact care was given to the preparation of food. Every cook was required to be a chemist of the highest excellence; another thing that struck me as radically different from the custom in vogue in my country. Everything was cooked by hot air and under cover, so that no odor was perceptible in the room. Ventilating pipes conveyed the steam from cooking food out of doors. Vegetables and fruits appeared to acquire a richer flavor when thus cooked. The seasoning was done by exact weight and measure, and there was no stirring or tasting. A glass tube, on the principle of a thermometer, determined when each article was done. The perfection which they had attained as culinary chemists was a source of much gratification to me, both in the taste of food so delicious and palatable, and in its wholesome effect on my constitution. As to its deliciousness, a meal prepared by a Mizora cook could rival the fabled feasts of the gods. Its beneficial effects upon me were manifested in a healthier tone of body and an an increase of animal spirits, a pleasurable feeling of content and amiability. The Preceptress told me that the first step toward the eradication of disease was in the scientific preparation of food, and the establishment of schools where cooking was taught as an art to all who applied, and without charge. Placed upon a scientific basis it became respectable. "To eliminate from our food the deleterious earthy matter is our constant aim. To that alone do we owe immunity from old age far in advance of that period of life when your people become decrepit and senile. The human body is like a lamp-wick, which filters the oil while it furnishes light. In time the wick becomes clogged and useless and is thrown away. If the oil could be made perfectly pure, the wick would not fill up."
