Some stars to the north do not rise or set at all, as seen from the northern parts of Europe and North America. They only travel round and round, in a circle about the Pole-star, which is almost exactly over our north pole. Yet their movements too are from east to west. If we lived in the southern hemisphere we should see the same thing going on nightly, only with a different set of stars. Then the far-south stars would circle round and round over the south pole; and those lying over the north pole would be hidden by the Earth lying between. But still the whole movement would be always from east to west; never from west to east. Each tiny star, bright or dim, takes its daily journey, like the sun, once in twenty-four hours. No matter whether it has to go right round the whole Earth or whether it only has to creep in a small circle round the Pole-star--still the journey is always the same in length: always close upon twenty-four hours. At the end of twenty-four hours it is back at its starting point, and begins over again. Just as the Sun does. If you look out at night sometimes, and watch carefully, you will see for yourself something of this constant nightly journeying of the stars. QUESTIONS. 1. Where does the Sun rise and set? The Sun rises in the East and sets in the West. 2. Always in the East and West exactly? Always to the east of our world and to the west of our world. Not due east and due west of each particular country always. 3. When is the Spring Equinox? On the twenty-first of March. 4. When is the Autumn Equinox? On the twenty-first of September. 5. What does the word Equinox mean? Equal nights. At the Equinox, days and nights are of the same length over almost the whole world. 6. When is the Summer Solstice? On the twenty-first of June. 7. When is the Winter Solstice? On the twenty-first of December. 8. In what direction does the Sun rise and set at the Equinoxes? At each of the equinoxes the sun rises due east, and sets due west, over all the world, except at the poles. 9. At the Summer Solstice where does the Sun rise and set? To people in England, or in Canada, or in the northern States, he rises in the north-east and sets in the north-west. 10. And in the Winter Solstice? To those same places he rises then in the south-east and sets in the south-west. 11. What do we call the highest point in the heavens, exactly over one’s head? The zenith. 12. Does the Sun ever reach the zenith in England, or in the northern parts of North America? Never. He rises much higher in summer than in winter at midday, but he is always to the south of the highest point. 13. When or where may the Sun be seen precisely overhead? On the equator, at the two equinoxes. 14. At what hour of the day may the Sun be seen exactly overhead? Only at Mid-day. 15. Do any other heavenly bodies rise and set? Yes; the Moon and the Stars; in fact, nearly all the heavenly bodies.
