The very highest point in the sky, exactly over one’s head, is called “the zenith.” In northern countries the Sun never gets to the zenith. No; not even on the very hottest summer day. He is always towards the south. There are two other dates, which you ought to learn, besides the _Spring Equinox_ and the _Autumn Equinox_. These are--the _Summer Solstice_, on June 21; and the _Winter Solstice_, on December 21. On the 21st of June the Sun is not exactly overhead at the Equator, as at the Equinoxes. He has come farther north; not nearly so far north as England or Canada, but as far north as he ever does come. By that time days and nights are not at all equal through the world. In the north of Europe and America we have long days and short nights; while our friends in Australia have long nights and short days. Although the Sun is never actually overhead with people in the northern parts of Europe and America, but is always somewhat to the south, even at his highest point, still he climbs very much higher in June than in March or September, and so he is much longer above the horizon. Things are quite the other way on the 21st of December. Then the Sun is overhead, not farther north than the Equator, but farther south. Then it is summer in the southern hemisphere and winter in the northern. Then we who live in England or in the northern parts of North America have long nights and short days, while our friends in Australia are having long days and short nights. Then, too, in the north, the highest point at mid-day which the Sun can reach is low down in the south; and his rays come to us in a slanting manner, with far less power to warm than when they are poured down from nearly overhead. That is why we are so cold in the dark months of the year. At the equinoxes the Sun rises to the east and sets to the west of almost the whole Earth. In our northern summer the Sun rises to the north-east, travels round by the south, and sets in the north-west. In our northern winter, the Sun rises to the south-east, climbs up a little way, and sets in the south-west. These changes come about slowly. Every twenty-four hours there is a difference. Each day of spring the Sun rises and sets a little more to the north, and climbs higher in the sky. Each day of autumn he rises and sets a little more to the south, and climbs less high in the sky. But all the while, though he may rise to the north-east or south-east of New York or London or some other particular spot, he rises to the east of the _world_; though he may set to the north-west or south-west of any particular spot, he sets to the west of the _world_. You will find a grand description in the 19th Psalm of this daily journey of “the Sun, which is as a bridegroom coming out of his chamber, and rejoiceth as a strong man to run a race. His going forth is from the end of heaven, and his circuit unto the ends of it; and there is nothing hid from the heat thereof.”
