Small World Dept: The one-hole putting green at Camp David was built in 1957 for President Eisenhower by none other than Robert Trent Jones, the celebrated golf course architect. It's the only one-holer he ever designed.

Now meet his son, Robert Trent Jones Jr., of Palo Alto, Calif., also a golf course architect. Robert Jr. is more interested than most in what happens at the camp summit.

For Robert Jr. designed that controversial course near the Pyramids - actually completed; all they need do is plant the greenery and start watering - which was suspended because of local politics, he believes.

Jones hopes that President Anwar Sadat returns to Egypt in an expansive mood, eager to encourage tourism and especially golfers. It could happen if the summit talks succeed.

The 18-hole course, shaped like the ankh, an ancient long-life symbol, is tow miles in the desert beyond the Pyramids. Jones feel the archaelogical abjections are unjustified, since there already is a golf course beside the Mena House Hotel, hardly a five-iron shot from the great monuments.

By the way, golf is very big in Asia and parts of Africa, Jones says, at least two Egyptian players regularly compete in the international contest in Alexandria, north of Carolina, has a stunning course. And you can't beat the climate.
