...weapon in flushing the enemy from his tunnel cities has been non-toxic CN tear gas-the use of which has brought screams of protest from critics in the U.S. Military men argue that gas is the only way of safely separating noncombatant Vietnamese hiding underground from Viet Cong. Often the gas is pumped into the tunnel complexes by means of long hoses attached to gasoline-driven pumps, but gas grenades are usually used. Last week U.S. troops in Tay Ninh were hit by Communist gas grenades. With that, the argument against U.S. use of nontoxic gas went...
...professional forester, I live and work among millions of trees. These, according to Professor Went [Sept. 9], produce an "incredibly toxic" blue haze. I have lived in Pittsburgh before smoke control. I have known gasoline smog in Southern California, and pulp mill smog in the north. I have endured wood "smog" in mill towns and near forest fires. Somehow, in spite of the "blue haze," the mountain air seems pure, refreshing and invigorating.

They emit molecular substances known as terpenes and esters, which react with sunlight to form a smog similar to the one produced by man-made pollutants. Terpenes, says Went, like some industrial and automobile pollutants, are "incredibly toxic." In some parts of the West, where they are generated by sage, they actually inhibit the growth of other vegetation...

To save weight, and make easy changes in the cabin configuration, seats are not moored to the floor as firmly as possible. Stewardess training is sometimes more of a brief charm school than a careful safety course. The lines have also handled safety drills and demonstrations...
...barrages of propaganda against the high cost of living, food shortages, the draft, and demand wage increases and better jobs. In rural areas, the protests should center on allied air and artillery strikes and "the plan to herd people with their unhusked rice into concentration centers and to use toxic chemicals in the massacre of our compatriots." Then there is the subtler approach, such as paying calls on the wives of Vietnamese troops "to inquire about the health of their husbands" and thus undermine civilian morale. Or, when an air attack is over, one might transport "the most typical victim...
