STONE AGE MAN IN BRITAINThe British Isles were not always the green and pleasant land in which we live to-day. Many thousands of years ago they were not even islands. The Straits of Dover did not exist, and England was joined to France by dry land.In those far off times no one lived here because the land was covered with ice hundreds of feet thick. Where there are now valleys, were what are called glaciers: great rivers of ice slowly moving down hill to the sea.These glaciers weighed millions of tons, and as they moved, they scraped away the rocky sides of the hills. This is how many of the valleys in the British Isles were formed.Then slowly the climate became warmer and the ice melted, leaving the bare rock underneath. There were no trees or flowers, and many hundreds of years passed before the land was fit for men to live in.
