...Swamp, drainage ditches for new housing may interrupt the already imperiled water flow into the Everglades. To the north, Walt Disney Productions is building a City of Tomorrow for 50,000 people that may cut off some of Orlando's water supply, since the site is atop porous soil that lets rainwater into Florida's vital aquifer. That underground layer of limestone stores much of the state's annual 57 inches of rainfall.

Lunar Past. Fra Mauro is a particularly interesting highland area. Blanketed with rock and soil, it is covered with debris that was probably ejected by the massive impact that created Mare Imbrium, or Sea of Rains, some 300 miles to the north. Indeed, some of this primordial matter, thrown up from depths of 100 miles or more, may have been involved in the original formation of the moon. Fra Mauro is probably also covered by other layers of debris that were spewed out by the meteorite impacts that created the craters Eratosthenes and Copernicus. In addition, volcanic material...

More ominously, Acting Head of State Cheng Heng charged that Viet Cong forces on Cambodian soil "have begun actions against the Cambodian people and our soldiers" near the border, and Prince Sirik Matak warned that an attack by thousands of Communist troops "could not be ruled out." There were reports that several thousand Communist troops had entered the country to foment trouble, and the new government...
