The Laplander of the far North uses the reindeer to pull his sled, its flesh for food, its skin for clothing, and its horns for various purposes.
How did men discover that they could travel on the water? Some one may at first have made use of a log to cross a river and, afterwards, have tied several logs together, making a raft. When they had learned how to make a canoe out of a log, by burning or hewing it out with rude axes, they could then take long journeys on the water to new lands. Since paddling was very tiresome, some one, brighter than the rest, probably thought of making a sail of bark or skins and so letting the wind push the canoe along.
We do not know how the metals were discovered. Perhaps fire melted some of the copper in a vein of ore. Perhaps pure copper was found, for Nature sometimes leaves it in this form. Copper could be easily hammered into various useful articles, but it was too soft for many needs. After tin was discovered, it was learned that by melting it and copper together a new and very hard metal, known as bronze, was formed. Next, we think, came the discovery of iron, which has become so important that we could not get along without it. Think what this must have meant for them! To get firewood, to make rude boats and simple houses, to fight wild animals, now became easier. After iron they discovered gold and silver, and began to take an interest in making beautiful as well as useful things.
It is easy to see how, once these new ways of using the earth were found, men could move into other regions than the belt where it was always warm. They could store up food for the winter, they could build warm shelters and get warm clothing, and they could sit by a fire.
Sometimes when the first people were out hunting, instead of killing the young animals that they caught, they took them home and cared for them. So the little creatures became quite tame and grew up about the camps. The wild jungle fowls were the ancestors of the domestic hens which we find so useful. The wild cow was tamed in like manner, and made to supply milk in addition to food and clothing. The colts of wild horses and donkeys were captured and used for carrying loads. Sheep and goats were tamed in the same manner, and became the most valued possessions of some of the ancient peoples as they are of some peoples today. When they had learned to weave the wool of these animals into clothing and blankets, they had taken another step upon the long road which leads from ancient times down to us.
Did these early people live entirely upon meat? If they had done so, we should never have had the wonderful variety of fruits and vegetables that we now enjoy so much. We must not suppose that Nature grew these things wild just as they are found in our gardens today. Our ancestors grew them for many generations, gradually improving their size and flavor. By selecting the best and carefully cultivating them, we are still continuing to make them better.
The horse, donkey, cow, and camel proved valuable in another way to the people who were learning to cultivate the ground. When harnessed to a crooked and sharpened stick they aided in breaking up the ground in which the young plants were growing.
And so the long years passed while the early people were discovering and making use of the things around them. They came to building better and more permanent homes, because they did not have to move from place to place in search of food. Where there were forests, wood served for their buildings. Where there were few trees, stone or mud bricks were used.
The brighter people learned to understand Nature more quickly than those who were dull. Each discovery of some new way of doing things aided them in making others, and in this way people finally came to have all the comforts of today. Those people less quick to learn the secrets of Nature, or those who lived in countries to which Nature had given little, gained few comforts and even now remain savage.
