Red Rock Canyon, part of the Red Rock Recreation Lands in Nevada, is an escarpment of crimson Aztec sandstone cliffs and canyon walls that reveal the geologic history of the area. Bands of sediment layers tell of a deep-sea bed that 400 million years ago rose eastward to a shoreline in present-day western Utah. As the ancient sea grew progressively more shallow, about 225 million years ago, marine limestone and shales were overlaid by sediments washed in from emerging land areas. As the water in the shallow inland seas evaporated, salts and minerals were deposited in thick beds and fluctuating shorelines created intermixed beds of limestone, shales, and minerals. Sediments from this period gave the canyon its name. Their red color was created from the weathering of iron compounds within. About 180 million years ago, the area became arid and was covered in sand dunes more than 2,000 feet deep, which became cemented into the Aztec sandstone that is prominent in the canyon today. Its alternating hues of red, yellow, and white are believed to have resulted from groundwater percolating through the sand and leaching out the oxidized iron.

The forest from which Man takes his timber is the tallest and most impressive plant community on Earth. In terms of Man's brief life it appears permanent and unchanging, save for the seasonal growth and fall of the leaves, but to the forester it represents the climax of a long succession of events.
No wooded landscape we see today has been forest for all time. Plants have minimum requirements of temperature and moisture and, in ages past, virtually every part of Earth's surface has at some time been either too dry or too cold for plants to survive. However. as soon as climatic conditions change in favour of plant life, a fascinating sequence of changes occurs, called a primary succession. First to colonize the barren land are the lowly lichens, surviving on bare I rock Slowly the acids produced by these organism crack the rock surface, plant debris accumulates and mosses establish a shallow root - hold. Ferns may follow and, with short grasses and shrubs, gradually form a covering or plant life. Roots probe even deeper into the developing soil and eventually large shrubs give way to the first trees. These grow rapidly, cutting off sunlight from the smaller plants, and soon establish complete domination closing their ranks and forming a climax community which may endure for thousands of years.
Yet even this community is not everlasting. Fire may destroy it outright and settlers may cut it down to gain land for pasture or cultivation. If the land is then abandoned, a secondary succession will take over, developing much faster on the more hospitable soil. Shrubs and trees are among the early invaders, their seeds carried by the wind, by birds and lodged in the coats of mammals. For as long as it stands and thrives, the forest is a vast machine storing energy and the many elements essential for life.


1. In "a primary succession" (line 11), what makes it possible for mosses to
take root

I arrived in London at last. The railway station was big, black and dark. I did not know the way to my hotel, so I asked a porter. I spoke English not stilly very carefully, but dearly as well. The porter, however, could not understand me. I repeated my questions several times and at last he understood. He answered me, but he spoke neither slowly nor dearly. "I am a foreigner" , I said. Then he spoke slowly, but I could not understand him.
My teacher never spoke English like that! The porter and I looked at each other and smiled. Then he said something and I understood it. "You'll soon learn English!" 'he said. I wonder. In England, each man speaks a different language. The English understand each other, but I don't understand them!

East Somalia's prolonged shortage of rain, which has already caused food supplies to fail and brought unemployment in farming areas, could also affect the production of electricity, and thus reduce the output from the nation's mines. The mining industry, and especially copper mining, uses a huge amount of electricity and is almost completely dependent on the government Electricity Supply Commission. But the Commission has recently asked the mines what would happen if electricity supplies were reduced by ten, twenty or thirty per cent.
The Commission's power stations, which produce the electricity using coal as fuel, are mostly situated near the large coalfields of Eastern Province. But this area has little water so the cooling towers at the power stations have to be supplied with water from elsewhere. The problem now is that water levels in all rivers and lakes have fallen dangerously low and, in some cases, are well below the intake pipes which feed into the pipelines which supply the cooling towers.
In a desperate attempt to solve the problem, engineers are spending some forty million dollars on building a series of small dams across the Haro river. It is hoped that these dams will make the water level at the Malawa Dam rise so that water can then be pumped through a new pipeline to the power stations. This will take time and it is now the dry season. Very little rain falls before October or November, and, after a shortage which has lasted for four years and is believed to be the worst in two centuries, nobody can say whether the rains will be sufficient.
The amount of electricity and water used by the mines has tended to increase in recent years. The mines, which produce about half the country's export earnings, need electricity in order to pump fresh air through their workings and to drive machines which crush vast quantities of rock. Each mine also has to provide accommodation for as many as three thousand workers.
