Gentol[a:], in this chain of spring-fed lakes the great river rises, and during a considerable portion of the year its volume is greatly enlarged through melting snows and frequent rains of this rather cold but humid region. We will follow its course southward so that you may observe the cities, towns and villages lining its banks, and the various kinds of craft traversing its navigable length. You perceive that Pfylonna, the city beneath us, is at the head of navigation, and we with profit and pleasure might pass an hour in viewing its points of interest, but not now, for time is flying and at any moment we may be called to D[a:]o. Yes, this northern region is more picturesque than are the lands of the Temperate and Equatorial countries, which, as we proceed southward, stretch into great level plains which sustain a dense population, largely of agriculturists. Yonder, on the eastern bank of the river, is a pretty, wooded height, the remnant of a mountain chain of the long ago. Now its slight elevation is little more than a sufficient barrier against the tumultuous floods, which during the spring pour down between it and the stone embankments of Cēhylû Ooltom[a:]h's western shore. Yes, Ento's Waterways, Irrigating System, Embankments and other stupendous works excite wonder and admiration for the skill, industry and enterprise involved, but generally, when self-preservation is at stake, humanity rises superior to emergencies. Inidor[a:], while we hastily survey the surrounding country, will you learn if the Istoir[a:] may be interesting enough to engage our attention? Some rural Istoir[a:]s possess very attractive features. Inidora--I feel strongly impelled to gratify your curiosity and my own. I shall be gone but a moment, and if worth while will summon you. De L'Ester--Again we are near the northern limit of the Irrigating and Waterways System, and to what a state of perfection it has been brought. Those great Structures are pumping Stations, and so excellent is the mechanism employed that the water distribution is under perfect control. The government of Ento indulges in no half-way measures. Whatever is done is done as well as can be accomplished.
