U.S. Encouraged by Vietnam Vote: 

Officials Cite 83% Turnout Despite Vietcong Terror

 WASHINGTON, Sept. 3-- United States officials were

surprised and heartened today at the size of turnout

in South Vietnam's presidential election despite a

Vietcong terrorist campaign to disrupt the voting. 



 According to reports from Saigon, 83 per cent of the

5.85 million registered voters cast their ballots

yesterday. Many of them risked reprisals threatened by

the Vietcong. 



 The size of the popular vote and the inability of the

Vietcong to destroy the election machinery were the

two salient facts in a preliminary assessment of the

nation election based on the incomplete returns

reaching here. 



 A successful election has long been seen as the

keystone in President Johnson's policy of encouraging

the growth of constitutional processes in South

Vietnam.
