The senior West German scientist in charge of the Community's solar energy program, Mr. Joachim Gretz, told journalists that at present levels of research spending it was most unlikely that solar energy would provide as much as three percent of the Community's energy requirements even after the year 2,000. But he said that with a modest increase in the present sums, devoted by the EEC to this work it was possible that the breakthrough could be achieved by the end of the next decade.

A rapid means of long-distance transportation became a necessity for the United States as settlement (新拓居地) spread ever farther westward. The early trains were impractical curiosities, and for a long time the railroad #panies met with troublesome mechanical problems. The most serious ones were the construction of rails able to bear the load, and the development of a safe, effective stopping system. Once these were solved, the railroad was established as the best means of land transportation. By 1860 there were thousands of miles of railroads crossing the eastern mountain ranges and reaching westward to the Mississippi. There were also regional southern and western lines.

The high point in railroad building came with the construction of the first transcontinental system. In 1862 Congress authorized two western railroad #panies to build lines from Nebraska westward and from California eastward to a meeting point, so as to #plete a transcontinental crossing linking the Atlantic seaboard with the Pacific. The Government helped the railroads generously with money and land. Actual work on this project began four years later. The Central Pacific Company, starting from California, used Chinese labor, while the Union Pacific employed crews of Irish laborers. The two groups worked at remarkable speed, each trying to cover a greater distance than the other. In 1869 they met at a place called Promontory in what is now the state of Utah. Many visitors came there for the great occasion. There were joyous celebrations all over the country, with parades and the ringing of church bells to honor the great achievement.
