The bears and moles get up; the flies and bees awaken; the gnats are hatched, and the fish come out from their eggs, when it is warm. Who has done it all?--The sun. The air gets warmed up in one place, and rises, and in its place comes colder air,--and there is a wind. Who has done that?--The sun. The clouds rise and begin to gather and to scatter,--and the lightning flashes. Who has made that fire?--The sun. The grass, the grain, the fruits, the trees grow up; animals find their food, men eat their fill, and gather food and fuel for the winter; they build themselves houses, railways, cities. Who has prepared it all?--The sun. A man has built himself a house. What has he made it of? Of timbers. The timbers were cut out of trees, but the trees are made to grow by the sun. The stove is heated with wood. Who has made the wood to grow?--The sun. Man eats bread, or potatoes. Who has made them grow?--The sun. Man eats meat. Who has made the animals, the birds to grow?--The grass. But the grass is made to grow by the sun. A man builds himself a house from brick and lime. The bricks and the lime are burnt by wood. The wood has been prepared by the sun. Everything that men need, that is for their use,--all that is prepared by the sun, and on all that goes much sun's heat. The reason that men need bread is because the sun has produced it, and because there is much sun's heat in it. Bread warms him who eats it. The reason that wood and logs are needed is because there is much heat in them. He who buys wood for the winter, buys sun's heat; and in the winter he burns the wood whenever he wants it, and lets the sun's heat into his room. When there is heat, there is motion. No matter what motion it may be,--it all comes from heat, either directly from the sun's heat, or from the heat which the sun has prepared in the coal, the wood, the bread, and the grass. Horses and oxen pull, men work,--who moves them?--Heat. Where does the heat come from?--From the food. And the food has been prepared by the sun. Watermills and windmills turn around and grind. Who moves them?--Wind and water. And who drives the wind?--Heat. And who drives the water?--Again heat. Heat raises the water in the shape of vapour, and without this the water would not be falling down. A machine works,--it is moved by steam. And who makes steam?--Wood. And in the wood is the sun's heat. Heat makes motion, and motion makes heat. And both heat and motion are from the sun. STORIES FROM ZOOLOGY THE OWL AND THE HARE It was dusk. The owls began to fly through the forest to find some prey. A large hare leaped out on a clearing and began to smooth out his fur. An old owl looked at the hare, and seated himself on a branch; but a young owl said to him: "Why do you not catch the hare?" The old owl said: "He is too much for me: if I get caught in him, he will drag me into the woods." But the young owl said:
