...Madison Street and the hillbillies of the "uptown area," a middle-class neighborhood only a decade ago. Virtually every city has its Negro slums: Detroit's Brewster, Chicago's West Garfield Park, Las Vegas' West Side and Los Angeles' now notorious Watts. The rural poor cluster in the picturesque Appalachians and the Ozarks, on the Louisiana-Texas coastal plain, in the southern Piedmont and the Upper Great Lakes areas where the land is as beaten as the people...
...each cluster, the Montana seismometers are set like spokes in a wheel, and at the center of each wheel is a small vault housing instruments for collecting the seismic signals. After the signals are picked up and amplified, they are translated into digital data and transmitted over telephone lines and radio to a data-processing center in a converted poolroom 140 miles away in Billings. The signals are eventually sent to M.I.T.'s Lincoln Laboratory in Lexington, Mass., where computers are programmed to determine more precisely the source and direction of the vibrations and whether they were caused...
...sometimes grows below a dam but not above it. In some places, once destroyed, the plant does not grow back; in most other places, it returns as tough as ever. On the Nile, where Egypt spends $1,500,000 annually on hyacinth eradication with dredges and herbicides, the plants cluster to form islands strong enough to support animals. "You can never let up," says William E. Wunderlich, aquatic growth control chief of the New Orleans District of the Army's Corps of Engineers. "I've seen a 300-h.p. tug stopped tight by water hyacinth...
...make the museum a center for young artists, Maeght had a cluster of cottages erected, complete with music rooms, studios, servants' quarters and a fine French chef. Given a trial run last December by a trio of Americans, the project proved a great success. One, Painter Ellsworth Kelly, so responded to the luxuriant Riviera landscape that his style underwent a major transformation. Maeght eagerly awaits his next group of artists-in-residence in September: "I hope to produce explosive encounters by putting them in contact...
...planes are dropping Lazy Dogs, which explode in the air and spray the ground with small, razor-sharp projectiles; Cluster Bombs, loaded with hundreds of small bombs, explode after they have penetrated the jungle canopy, and Shrike and Bullpup air-to-ground guided missiles zero in on preselected targets. Ingeniously designed for low-flying missions is the Snakeye, a bomb that upon release opens an assembly of metal ribs like an umbrella's skeleton. The sudden increase of air resistance retards the falling bomb and thus permits the jet that drops it to escape the blast of detonation...
