...Floods. Rain is an even greater threat than an eruption, Tazieff has warned. Only last December the flooded Reventado River pushed thousands of tons of volcanic mud onto the out skirts of Cartago, killing 13 people and wrecking hundreds of homes. Now the danger is worse. A thick layer of unstable ash has accumulated in the area between Cartago and the smoking mountain. With the rainy season approaching, it may turn into a slithery morass and, faster than a man can run, slide down the valleys, picking up rocks and trees. The first heavy rain to soak Irazú, Tazieff...
...stuff gets even smaller. Integrated circuits that include everything, even transistors, are built into a single chip of silicon. Westinghouse starts with a sheet of silicon eight one-thousandths of an inch thick and about the diameter of a quarter. On top of this, an even thinner layer of extra-pure silicon is deposited by evaporation and covered with photosensitive masking material. The mask is removed in patterns, allowing successive parts of the silicon to be exposed to vapors, such as boron, that change its electrical properties. Some of the tiny areas become built-in transistors; others become diodes, capacitors...
...Pont already has a thriving competitor in tiny Arnav Industries of New Jersey, which is making a roughly similar material of its own for children's shoes. Britain's Courtaulds also makes a similar material, which will not breathe but will hold moisture in an inner layer until the shoe is removed. All competing processes will have to differ substantially from Du Pont's, since the firm holds patents on just about everything but the word shoe...
Burned City. After mobilizing 130 Arab laborers from nearby villages, Dr. Pritchard sank 30 pits at the northwest part of the mound. The much-eroded surface layer was probably the remains of the last city to occupy the mound, apparently abandoned about 700 B.C. A few feet below the surface were the floors, streets and wall-footings of an older city that was destroyed by fire. Grey wood ash was everywhere, sometimes mixed with charred beams and mud from fallen roofs...
...average $10, plus an extra $4 for fitting and styling. Manhattan's Janus Mann Eyelash Salon sells models in mink (for $50) and sable (for $80) to customers who want to match their coats. Women like them so much that they are wearing as many as three sets (layer upon layer) at a time, achieving a wild, bushy-eyed effect. Their lids may droop under the burden and their vision blur, but there seems to be no end in sight for the whole blinking business...
