Khrushchev Mingles With Crowds As Train Nears San Francisco

ABOARD KHRUSHCHEV TRAIN, Sept. 20--A bouncy Nikita Khrushchev whistle-stopped his way toward San Francisco today, freely meeting and shaking hands with ordinary Americans for the first time.

Exulting in what he chose to call his liberation from "house arrest" of security, the Russian Premier got off the train carrying him from Los Angeles at nearly every stop and mingled with tightly packed station crowds.

Only Saturday night he angrily had threatened to fly home to Russia when stung by what he considered provocative questions.

Sunday, however, it was a smiling, cheery Khrushchev who said after mingling with station crowds:

"Why should I go home? Just think: a little girl waving to a Communist!"

In a series of hectic interviews, as he strolled down the aisle of his special train, Khrushchev--

1. Denounced as "immoral" the leg-kicking and skirt-tossing can-can dance put on for him when he visited a Hollywood studio.

2. Blasted anew at Los Angeles Mayor Norris Poulson "and the organizers" of a dinner in his honor Saturday night.

3. Testily insisted he had no interest in seeing American missile bases because "we have enough of our own and ours are better."

4. Said Russia would stop jamming British broadcasts to Russia "if BBC reverts to a good position."
