Most of the time of the trip was spent by Larner in listening to explanations of customs and traditions of the people of the brightest planet in the universe. There was a question Larner had desired to ask Nern Bela, yet he hesitated to do so. Finally one evening during the journey to Venus, when the travelers had been occupying themselves in a scientific discussion of comparative evolution on the two planets, Larner saw his opportunity. "Why," he asked rather hesitatingly, "did the people of Venus always remain so small? Why did you not strive more for height? The Japanese, who are the shortest in stature of earth people, always wanted to be tall." "Without meaning any offense," replied Nern, "I must say that it is characteristic of earth dwellers to want something without knowing any good reason why they want it. It is perfectly all right for you people to be tall, but for us it is not so fitting. You see, Venus is smaller than the earth. Size is comparative. You think we are not tall because you are used to taller people. Comparatively we are tall enough. In proportion to the size of our planet we are exactly the right size. We keep our population at 900,000,000, and that is the perfectly exact number of people who can live comfortably on our planet." * * * * * Arriving on Venus, Larner was assigned a laboratory and office in one of the Government buildings. It was a world seemingly made of glass. Quartz, of rose, white and crystal coloring, Larner found, was the commonest country rock of the planet. In many cases it was shot full of splinters of gold which the natives had not taken the trouble to recover. This quartz was of a terrific hardness and was used in building, paving, and public works generally. The effect was bewildering. It was a world of shimmering crystal. The atmosphere of Venus had long puzzled Larner. While not an astronomer in the largest sense of the word, yet he had a keen interest in the heavens as a giant puzzle picture, and he had given some spare time to the study. He knew that from all indications Venus had a most unusual atmosphere. He had read that the atmosphere was considerably denser than that of the earth, and that its presence made observation difficult. The actual surface of the planet he knew could hardly be seen due, either to this atmosphere, or seemingly perpetual cloud banks. He had read that the presence of atmosphere surrounding Venus is indicated to earthly astronomers, during the planet's transit, by rings of light due to the reflection and scattering of collected sunlight by its atmosphere. Astronomers on earth, he knew, had long been satisfied of the presence of great cloud banks, as rocks and soils could not have such high reflecting power. He knew that like the moon, Venus, when viewed from the earth, presents different phases from the crescent to the full or total stage.
