...Russians rejected it as an espionage ploy. The Russians countered with a ground checkup system -which Eisenhower accepted in principle-but the idea fell through when Moscow would allow only three token look-sees a year. Today there is still no formal inspection procedure, although satellite surveillance and seismic detection devices have made it easier to keep track of nuclear installations and large detonations worldwide...

...seismic impact of Johnson's withdrawal statement has only begun to be felt. Politically, it means a bitter battle for the succession among Democrats and an anguished reappraisal among Republicans concerning Richard Nixon's chances for election in November. Within the U.S., it could mark the beginning of a frenetic effort by Johnson to complete the record of domestic legislation that he wants to stand as history's yardstick for his presidency. In foreign affairs, it could bring more intense efforts to end the war?either by negotiations or by heavier fighting. In any event, the President no longer...

Working with a $1.50 globe of the world, Rouse picked a seismic zone off the coast of Chile and projected it into an imaginary flat surface or plane slicing through the earth. He discovered that along the circle formed where the plane intersected the surface of the earth there were other earthquake and major fault zones-in the Pyrenees Mountains, the Red Sea and the western tip of South America. During the next three weeks, Rouse projected the planes of other earthquake zones to form 15 additional circles, or belts, on the earth's surface...

...Telling Circles. Along the belts, he found, were most of the major seismic features of the globe: the ridges and faults associated with earthquake activity. Furthermore, most of the 19 points on the earth's surface where three Rouse belts intersected coincided with areas of major earthquake or volcanic activity. Significantly, the planes of the belts passed through the boundary between the earth's molten core and its solid mantle, each being approximately tangent to the core...

...their endless search for water, oil and minerals beneath the surface of the earth, prospectors and scientists have used everything from divining rods to sophisticated seismic devices. But more often than not, they have had to fall back on costly and time-consuming drilling to probe the earth's secrets. Now, New Mexico's Sandia Corp. has developed new tools for preliminary subsurface exploration that may do in minutes or hours what now takes days and even months to accomplish. The new devices: high-speed, instrumented projectiles dropped from aircraft or propelled by rockets...
