CHAPTER IX.
MANNERS AND CUSTOMS.
Next morning Esmo asked me to accompany him on a visit to the seaport I have mentioned. In the course of this journey I had opportunities of learning many things respecting the social and practical conditions of human life and industry on Mars that had hitherto been unknown to me, and to appreciate the enormous advance in material civilisation which has accompanied what seems to me, as it would probably seem to any other Earth-dweller, a terrible moral degeneration. Most of these things I learned partly from my own observation, partly from the explanations of my companion; some exclusively from what he told me. We passed a house in process of building, and here I learned the manner in which the wonders of domestic architecture, which had so surprised me by their perfection and beauty, are accomplished. The material employed in all buildings is originally liquid, or rather viscous. In the first place, the foundation is excavated to a depth of two or three feet, the ground beaten hard, and the liquid concrete poured into the level tank thus formed. When this has hardened sufficiently to admit of their erection, thin frames of metal are erected, enclosing the spaces to be occupied by the several outer and interior walls.
