rivers

68:5.2The ear­li­est hu­man cul­tures arose along the rivers of the East­ern Hemi­sphere, and there were four great steps in the for­ward march of civ­i­liza­tion. They were:

43:1.1Eden­tia abounds in fas­ci­nat­ing high­lands, ex­ten­sive el­e­va­tions of phys­i­cal mat­ter crowned with mor­ontia life and over­spread with spir­i­tual glory, but there are no rugged moun­tain ranges such as ap­pear on Uran­tia. There are tens of thou­sands of sparkling lakes and thou­sands upon thou­sands of in­ter­con­nect­ing streams, but there are no great oceans nor tor­ren­tial rivers. Only the high­lands are de­void of these sur­face streams.

46:2.2There are thou­sands upon thou­sands of small lakes but no rag­ing rivers nor ex­pan­sive oceans. There is no rain­fall, nei­ther storms nor bliz­zards, on any of the ar­chi­tec­tural worlds, but there is the daily pre­cip­i­ta­tion of the con­den­sa­tion of mois­ture dur­ing the time of low­est tem­per­a­ture at­tend­ing the light re­ces­sion. (The dew point is higher on a three-gas world than on a two-gas planet like Uran­tia.) The phys­i­cal plant life and the mor­ontia world of liv­ing things both re­quire mois­ture, but this is largely sup­plied by the sub­soil sys­tem of cir­cu­la­tion which ex­tends all over the sphere, even up to the very tops of the high­lands. This wa­ter sys­tem is not en­tirely sub­sur­face, for there are many canals in­ter­con­nect­ing the sparkling lakes of Je­ru­sem.
