Thanks to the protection of the tombs, so secure against the ravages of time if not against the hand of man, we possess a more complete sampling of Etruscan art in all its forms than we do of any other ancient European culture. Except for the frescoes of Pompeii and Herculaneum, the Etruscan frescoes supply the only insight we have into the techniques of painting in classical civilization. It is in southern Etruria, where the tombs were cut in the rock, that these frescoes are preserved. They are intact at least until the tomb is opened, whereupon deterioration begins. Fortunately it is now possible to remove the paintings from the walls and take them to the safety of the museum. The Etruscan painter used pleasantly simple mineral colors that be laid on a fresh layer of plaster applied to the rock wall. With large, uninterrupted surfaces to work on, he was prompted to make complex pictorial compositions. But his purpose is always clear. Enclosed forever in the tomb, his pictures were to evoke for the deceased the joys of life. The dead man’s occupation, which he intended to resume in the afterlife, is often depicted. Scenes of banquets and feasts are frequent. These guaranteed eternal satisfaction and pleasure to the departed; in the happy phrase of tile Belgian scholar Franz Cumont, "the ghost of a diner could be nourished by the appearance of food." The frescoes also perpetuated the pleasant hours of sports, games and dances. When Etruria came on difficult times, the funerary frescoes took on a more somber tone: the features of the departed, which were formerly peaceful, were expressions of anxiety and even of anguish. Etruscan sculptors preferred to work in clay or bronze rather than in stone. They were particularly fond of the bas-relief, in which they produced delightfully animated figures framed in elegant arabesques. Their forte, however, was the portrait. The art of portraiture had deep funerary significance: it furnished a faithful image of the deceased to aid his survival in the other life. Frequently, in the seventh century B. C. , the portrait of the deceased formed the lid of the crematory urn. Portraiture reached its peak in the last centuries of Etruscan civilization, when the characteristic Etruscan flair for detail, for the unusual, found its fullest expression. One kind of subject matter not found in the frescoes in the Etrurian tombs is ______.

The coastlines on the two sides of the Atlantic Ocean present a notable parallelism: the easternmost region of Brazil, in Pernambuco, has a convexity that corresponds almost perfectly with the concavity of the African Gulf of Guinea, while the contours of the African coastline between Rio de Oro and Liberia would, by the same approximation, match those of the Caribbean Sea. Similar correspondences are also observed in many other regions of the earth. This observation began to awaken scientific interest about sixty years ago, when Alfred Wegener, a professor at the University of Hamburg, used it as a basis for formulating a revolutionary theory in geological science. According to Wegener, there was originally only one continent or landmass, which he called Pangea. Inasmuch as continental masses are lighter than tile base on which they rest, he reasoned, they must float on the substratum of igneous rock, known as sima, as ice floes float on the sea. Then why, he asked, might continents not be subject to drifting The rotation of the globe and other forces, he thought, had caused the cracking and, finally, the breaking apart of the original Pangea, along an extensive line represented today by the longitudinal submerged mountain range in the center of the Atlantic. While Africa seems to have remained static, the Americas apparently drifted toward the west until they reached their present position after more than 100 million years. Although the phenomenon seems fantastic, accustomed as we are to the concept of the rigidity and immobility of the continents, on the basis of the distance that separates them it is possible to calculate that the continental drift would have been no greater than two inches per year. The submerged mountain range in the Atlantic ______.

A man-made chemical that attracts male gypsy moths by duplicating the natural attractant of female gypsy moths has been patented as No. 3,018,219. Dr. Martin Jacobson of Silver Spring, Md., assigned patent rights to the U. S. Government as represented by the Secretary of Agriculture. The chemical can be used to detect gypsy moth infestations, as well as to control the insects. The gypsy moth does serious damage to forest and shade trees in New England and eastern New York State. The caterpillars, or larvae, of gypsy moths eat the leaves of trees, often causing death by a single attack. Losses of hardwood trees have been estimated at tens of millions of dollars from a 20-year study. Gypsy moths were prevented from spreading to other U. S. forest areas by using the natural attractant of the female to detect infestations, then spraying with chemicals such as DDT to kill the insects. Since the lure could previously be obtained only by clipping the last two abdominal segments of the virgin female moth, extracting the segments with benzene and then processing to stabilize the chemical, the procedure was expensive. Another difficulty was that, as the gypsy moth population declined, it became increasingly hard to obtain the females needed for lure production. Dr. Jacobson overcame both these difficulties by discovering a synthetic method for making the female’s attractant chemical. The chemical is known as 12-acetoxy-l-hydroxycis-9- octadecene. It is so potent that the fraction of a drop produced by the female is 200,000 times more than the amount needed to catch a mate. The synthetic chemical is also very powerful--it works in amounts about equivalent to one drop in a box car. The flightless female gypsy moth mates only once a year and, as soon as she does, an enzyme switches off production of the sex attractant. The winged male, however, call mate several times and it is because of this that the chemical is being used for pest control. By using a mixture of attractant and DDT in traps lined with a sticky substance, enough males can be caught to reduce the gypsy moth population substantially. Dr. Jacobson’s chemical works by ______.
