All Eskimos live most of their lives close to salt or fresh water. They may follow game inland for several hundred miles, but they always return to the shores of rivers, lakes or seas. Eskimo land has a bare look. Large rocks, pebbles, and sand cover much of the surface. Plants called lichen grow right on rocks. And where there is enough soil, ever grass, flowers and small bushes manage to live. No trees can grow on the Eskimo land, so geographers sometimes call this country the Arctic plains. Some animals, such as rabbits and caribou, eat the plants. Others, like the white fox and grey wolf, eat the rabbits and caribou. The Eskimo is a meat-eater, too, and may even eat a wolf when food is scarce.
The Eskimo year has two main parts: a long, cold winter and a short, cool summer. Spring and fall almost too short to be noticed. Summer is the good time, when food is usually plentiful. But it is also the time when the Eskimos are very busy. Winter is never far away, and the men must bring home extra meat for the women to prepare and store. For seldom can enough animals be killed in winter to feed a family.
The Far North is sometimes called the land of the midnight sun. This is true in the middle of summer, for between April 21

and August 21

, the sun never sets in Northern Greenland. But in midwinter the Far North is a land with no sun shining at all. Around Oct. 21
st
the Eskimos of Northern Greenland see the sun setting straight south of them, and they don"t see it again until February 22
nd
. All places on earth get about the same amount of daylight during a year. As a result, if summer is lighter, winter has to be darker. Winter nights in the Far North are seldom pitch-black. As in the rest of the world, the stars and the moon provide a little light. The northern lights also help the Eskimos to see. And with the ground covered with snow, even a little light is reflected back to the Eskimo"s eyes.
