Lines of Tûz[a:]mos penetrate far northward and southward, and where they cannot go air Transports can and do go. Thus these communities are not at all isolated, and they go and come where and when they will. Some time, if you may so desire, you shall visit some of them, and I may assure you that you will find them very interesting. Yes, all mines are owned by the general government, and the remuneration of those engaged in them is so liberal, so equitable, as to assure to them prosperity and contentment. At the entrances of the various great mines are enormously lofty light towers, whose several floors are devoted to educational and other purposes. In the schools some of Ento's foremost scientists of the past and of the present day have been taught electric and hydraulic engineering, geology, mineralogy and other specialties. Other floors are for living rooms, nurseries, hospitals and the inevitable Istoir[a:]. The several departments are attractively finished and furnished, and are quite as desirable as are well appointed dwellings of milder climes. On the summits of these lofty towers are immense electric lights which are to navigators of space what beacon lights are to mariners of seas. To air voyagers they afford cheering assurance of their whereabouts and of hospitable entertainment; for, at all mining centres, are air Transport Stations for the accommodation of travellers and for shipping purposes. Frequently, in Arctic and Antarctic regions, terrific snow storms occur, and were it not for the far reaching tower lights, air pilots would not be able to find Transport landings, which ever are kept in readiness for their arrival. Yes, the mines are located in mountainous regions, for as the poles are approached the planet's surface is very rugged and mountainous, and as on all stable planets the more nearly the poles are approached the vaster are the mineral deposits. Yes, the same law applies to Earth, and were I not somewhat opposed to prophesying, I might say that within ten years the insatiable gold worshippers of our planet will set up their altars in localities nearly as frigid as are Ento's northern and southern mining regions. Much more in this direction I might relate, but we anticipate that later on we may afford you views of what I have given you a mere idea. Ah, here are George and Inez.
