Within the atmospheric belt from time to time, due to the heat and cold and other disturbances, moisture is formed so that now and then rain falls upon the surface of the growing ball, filling the lower levels and cavities and thereby making the lakes, rivers, and oceans. From time to time these waters spill over other territories of the planet by its tilting one way or another. As moisture from within and without the new planet dampens its surface and the enfolding atmosphere, the life germ within the dust particles is moved to activity. In the beginning a moss-like vegetation takes form in the creases and crevices of the surface where moisture is most prevalent. As time goes on and activity continues, larger and sturdier forms of vegetation grow forth from the life germ contained within the planet itself, also dependent somewhat on the temperature and moisture as well as the pressure of the enveloping atmosphere. After food and water have thus been brought forth, insect life appears upon the planet, then fowl life, next the animal, with the human form being the last and finest expression to inhabit this new planet. Here too is shown that during the growth and development of the planet as well as after inhabitation has taken place, upheavals known as volcanic action or earthquakes come from time to time. These are shown to be nothing but congestion of gasses accumulated in a period of time that eventually must escape in volume to the surface of the planet, for which man should be thankful. For if this wasn't possible, the planet would blow up into billions of parts like a balloon. As we approach the end of this immense room, we observe the beginning of retrogression towards disintegration of life upon the planet, as well as for the planet itself. In an adjoining room is a mechanical conception of the solar system complete, showing the sun as the central force and the radiation going out from its body in a terrific bombardment. It shows here that the sun is so cold that it is really hot. We can see how an invisible ray emanating from the body of the sun penetrated a sixty foot thickness of what we would call the hardest type of steel and its penetration turned the other side of that steel red. Dr. Johnston asked, "what is this power really?" "It is what men on Earth call atomic for convenience of expression," explained our host. "It is as good a name as any, but one thing we can say about it is, that it is electrical where it is repulsive as well as attractive, composed totally of a positive force; but to name it, we haven't been able to do that as yet. The only thing we know is that it is composed of seven different major elements that govern the solar system, and each tiny atom is made up of these seven elements." "Would it be possible for people to live on the sun?" asked Bob.
