Francis H. Duehay '55, assistant dean of the Ed School, finished first yesterday in the preliminary vote count for the Cambridge School Committee.

The second day of the City's election tally was a slow one. There were no new developments in the battle for nine City Council seats as Election Commission workers validated and recounted ballots to get an official total for each of the 20 candidates.

On the other side of the Longfellow School gymnasium, they were sorting the canary-yellow School Committee ballots and making an unofficial count.

Because Cambridge uses the complicated proportional representation system, final results of both elections probably will not be determined until tomorrow night.

The School Committee voting went much as expected. Duehay led the way with 3966 'number one votes," and all four of the six present Committeemen running for reelection finished in the top six.

Only John A. P. Good, who joined the Committee in January and has been under frequent fire from Duehay for "cronyism," is in danger of being unseated. Good now stands in sixth place, with 2355 votes, about 300 more than his closest rival, George J. Fanfani Jr.

Fourth In '65

Duehay had 4400 number one votes when he was elected for the first time gerald was fourth yesterday with 3239 votes, and Gustave M. Solomons, who like Duehay was endorsed by the Cambridge Civic Association, is running a strong second with 3724 votes.

The two new faces on next year's Committee will probably be Daniel J. Clinton and David A. Wylie. Clinton, who has just missed election twice before drew heavily on the central Cambridge votes that used to go to Committeeman George F. Olesen. And Wylie, one of nine candidates endorsed by the CCA, wooed support from the same constituency that elected Committeewoman Barbara Ackermann who this year ran for the Council.

So the composition of the new committee will be very similar to the old. The seventh chair will be occupied by the new mayor and it is possible that CCA-endorsed members will constitute a majority.

In the Council race at least four incumbents, maybe five, are in trouble--and all of them are members of the five-man majority that backed the choice of Joseph A. DeGuglielmo '29 for City Manager two years ago.

Right now Thomas Coates is tenth and William G. Maher eleventh, but in the redistribution of votes in the next two days Coates could finish ahead of Mayor Daniel J. Hayes Jr. or Cornelia B. Wheeler who stand ninth and eighth
