' mm exact order," said Cosmo, as they traveled in their plane through the sky. "But we thought you'd like to see the planets first on account of your Earth being a planet." "I hope I'll be able to recognize them now when I see them from the Earth," Harry said. "It would be dreadful not to know them by sight when I've talked to them." "Look over your , me bun isn t bo gky cliarts and Far Away. fi n d , , y 0 u r friends," Cosmo suggested. "But re- member that you'll see them In different dif-ferent places at different seasons I'll have to tell you something about that later. "Of course you'll always be able to see your own Moon and then It Is so nearby. After all, the Sun Isn't so far away a mere ninety-three million mil-lion miles." "A mere nothing," said Harry, chuckling. But Cosmo was quite serious seri-ous as he repeated Harry's words. "A mere nothing." Now the pilot took them for a little lit-tle ride and Cosmo said, "You'll have to use your imagination imagina-tion a good deal on this trip. "In the old days, as you know, people gave names to stars and made up stories about them. They saw pictures pic-tures in the way the stars wer grouped and named them after the different pictures they fancied they saw. "In your day, now, they do not Imagine Im-agine so much but they know more. I'm not so sure which Is really better of course to know more Is very fine, but It was Jolly the way they made up stories about the stars so many years ago. Your present-day people give numbers and letters to new stars Instead of names, and keep adding to the great figures and distances. "If you will draw a kind of outline around the groups of stars you will be able to fit In some of the old sky pictures." "Tell me this Cosmo. You spoke of It Just a minute or two ago. Why do we see the stars In one place and then In a few months see them In different places? That has always puzzled me. You said something about the seasons?" "In the time In which you go round the Sun," commenced Cosmo, (and Harry was once again so much amused at the way they all kept speaking to him as though he were the whole Earth) "a year passes. And so you're looking at the stars from a different position in the various seasons. "But dear me, now people are finding find-ing stars brighter than those of the first magnitude which was always the way they spoke of the brightest stars, so they'll have to be adding words to describe what they see !" "There's another thing, Cosmo, I don't see how they can take measurements measure-ments up In the sky." "Very much the same way as surveyors sur-veyors measure on land, but In the sky they must compare sizes, divide the sky Into regions and make use of high powered telescopes and photographic photo-graphic telescopes. It's pretty mathematical mathe-matical but If you are Interested you can find out all this when you're older and study higher mathematics." "Do the stars ever bump?" "There are some traffic regulations in the sky." "Besides the way the planets travel trav-el along the Zodiac?" "Oh, Indeed, yes, and then the distances dis-tances between stars keep them from bumping." "Do they go quickly?" "Well the Sun goes along at about twelve and a half miles a second. That's not very speedy. Twenty miles a second Is about average, though some go as quickly as six hundred hun-dred miles a second." sec-ond." "Isn't It dangerous danger-ous when they go that quickly?" "No. The more quickly a star travels, trav-els, the more It will keep clear of certain directions in the heavens." "L 1 k e having special roadways for rapidly moving '.

HfH-ry shouted. "Yes, good heavens." smiled Cosmo. "But you sre thpy gft used to keeping keep-ing their specl:il routes, and maybe once only In a good muny billion years would there he a collision!" |
