 What is hiding underneath the gigantic mound on the alien planet?
The ice-cap, by its existence and circular shape, proved that the planet rotated at a not unreasonable rate. A water-ice ice-cap said that there were no poisonous gases in the planet's atmosphere. The fact was verified by the thick, dense cloud-masses which covered most of the surface,—all the surface, in fact, outside the ice-cap. Two of the Nadine's four-man crew watched out the same ports as the planet seemed to approach. The process would be to find a planet and check its climate and relationship to other planets, and its flora and fauna against descriptions in the Directory. All five of its proper company watched as the planet's surface enlarged.
