Meanwhile, another Secret Service agent shouted: "Let's go!" The command was a signal to tell other agents in the area that Ford was in danger. Swiftly, a cordon of men formed around the shaken President. Two agents pulled down on his suit jacket, forcing the tall (6 ft. 2 in.) Ford to bend so that he was partially concealed by the group. Then, moving at a brisk walk, the party swept through the park past the startled spectators and into the safety of the capitol...
...bars these days, the men's costumes, with their coded signals, are so elaborate that even habitues are beginning to get confused. Keys dangling from a belt over the left hip generally signal a desire to be sexually dominant; on the right, a passive disposition. But the designations may change from city to city and bar to bar. An expert on left-right symbolism interviewed for the gay tabloid the Advocate last week warned of a further possible misunderstanding. If they are on the right side he said, it may just mean that the wearer is righthanded...
...most important signal, they said, was a change in the velocity of vibrations that pass through the earth's crust as a result of such disturbances as quakes, mining blasts or underground nuclear tests. Earth scientists have long known that tremors spread outward in two different types of seismic waves. P waves cause any rock in their path to compress and then expand in the same direction as the waves are traveling. S waves move the rock in a direction that is perpendicular to their path. Because P waves travel faster than S waves, they reach seismographs first...
...significant as those changes seemed, U.S. seismologists felt that they could not be really dependable as a quake-prediction signal without a more fundamental understanding of what was causing them. That explanation was already available. In the 1960s, while studying the reaction of materials to great mechanical strains, a team of researchers under M.I.T. Geologist William Brace had discovered that as rock approaches its breaking point, there are unexpected changes in its properties. For one thing, its resistance to electricity increases; for another, the seismic waves passing through it slow down...
...paid in cash, with no more than half of the bills in an "uncirculated" condition and at least 200,000 of them in $10 denomination. The kidnapers would use the code name "Raven" in making contact with the family and would disguise their voices with speech-altering devices. To signal that the ransom was ready for delivery, the Bronfman family should place a personal ad, signed "Fred Bollard," in New York newspapers...
