The land is the beginning of the story, and it is the land that gives the story its continuity.
Britain was a ready-made island when our forebears stepped ashore. They were practical men with their feet on the ground, but they were also pioneers, men with feet sensitive to the nature of the ground – feet that soon grew so familiar with it that they came to act as roots, exploring it downward and bringing up from it the nourishment and profit that lies beneath. They were pioneers; but they were also craftsmen, and a craftsman’s mind follows his hands and feet. So the stones thrown up by the pioneers from their deep workings have been cracked open and studied like pages torn from a buried book, until now we know the birth pains and the growth of this motherland of ours, and how much wealth lies latent in her still.
Millions of years in the making
This growth has been a gradual and continuous process, in which our present is only an instant. There is continuity in the formation and destruction of land, no less than in the evolution of the life that lives upon it. This is the kind of reality that can best be translated into images by a painter; Graham Sutherland’s mural, then, sets the mood for this Pavilion.
All climates beneath our feet
Britain is not a country of extreme climates, yet buried in the island are evidences of all extremes. Twenty thousand years ago, it was an arctic land, glaciers ground their way down the valleys of the Lake District. Fifty million years ago, the region of the Scottish Islands was burned by volcanoes, which poured lava and scattered ash over the surrounding land and sea. Before that, the region where Birmingham now stands was an inferno of blown desert sand. Earlier still, tropical jungle made Britain look like a South Sea island.
The land in labour
Here in this island is a greater variety and wealth of rocks than can be found in any other area so small. This, too, is the result of a slow, imperceptible continuity of change, of deep troughs formed in past ocean beds being filled to colossal depths by wastage from the land which have then been spewed up as new mountain ranges, piled high above the surface of the earth. These, in their turn, have been eroded away, leaving only their tortured stumps.
Had some magic cine-camera, using time-lapse photography, recorded events during, say, the last five hundred million years, it would seem to repeat itself several times. One such cycle, therefore, can illustrate the labour pains in the building of the British Isles; and a special film has, in fact, been made to illustrate them.
The rocks that were used thus by the vast forces in the earth are now the very wealth of the land.
The rocks are our riches
Our story starts a thousand million years ago when the rocks of north-west Scotland and the Outer Isles were formed. Four hundred and fifty million years ago, west Britain was a seabed blanketed with river mud. From those ancient muds our fine Welsh slates are split.
Later, warm seas stretched out across the northern latitudes, swarming with living things. These, through the ages, crusted the sea floor with their limestone skeletons and now the cliffs of the Avon Gorge, for example, reveal this useful stone.
Two hundred and twenty million years ago, Britain was coated with jungle-swamps, whose giant plants for generations drank in the light, died, decomposed and were covered by mud and sands. They were raised again above the sea – dead forests entombed by rocks. From their rich black coals we unlock to-day the power of the primeval sun.
Later still, there were stagnant seas over north-east England, the salt of which was thickened by hot suns. To-day, these salts are mined from deep down under Middlesbrough and used for table, factory and to fertilise the fields. One hundred and thirty million years ago, the iron ore of Northamptonshire was laid down in a shallow sea.
During the last seventy million years the geography of Britain has changed continually. The land has been dipped like a cloth in the ocean, soaked, rinsed and folded up to dry. For most of the time it was part of Europe. Then, about five hundred thousand years ago, glaciers and ice shrouded the land. To this freezing world came early man. When the ice caps had melted Britain emerged an island.
This is the story of the origins of the land, seen through the eyes of British geologists who introduced a new science to the world. For the British people this land still offers materials ready to hand to challenge their skill; still offers a coastline for seamen, a climate for farmers and a landscape of extraordinary variety.
