Nor was there any hasty action. The office of Mayor was not declared vacant until after Schmitz had been sentenced to the penitentiary. But Schmitz was in the county jail and incompetent to act. It was of immediate necessity that a temporary successor be substituted. Until this were done, San Francisco would be without a chief executive. To meet the emergency, the Supervisors named Supervisor Gallagher to be acting Mayor.[249] After the sentencing of Schmitz the rapidly developing situation made it necessary that the convicted official's office be declared vacant and his successor appointed. But the successor had not been named, nor had plans for the change in administration been formulated.[250] In this further emergency, it was decided to name one of the Supervisors to be Mayor to serve until a permanent successor of Mayor Schmitz could be named. The unhappy Boxton[251] was decided upon. The Supervisors, by resolution, definitely declared the office of Mayor vacant and elected Supervisor Boxton to be Mayor. On the day that Boxton was named Mayor of San Francisco, District Attorney Langdon made public a plan for a convention to select a Mayor to serve until the successor of Mayor Schmitz could be elected and qualified. Mr. Langdon proposed that the convention should be made up of thirty members, fifteen to be appointed by organized labor and fifteen by the organized commercial bodies. On the side of Labor were apportioned eight delegates to the Labor Council and seven to the Building Trades Council. The five commercial bodies, the Chamber of Commerce, Merchants' Association, Board of Trade, Real Estate Board and Merchants' Exchange, were allowed three delegates each. That the convention might proceed in its choice unhampered, the District Attorney pledged that he and his associates would wholly refrain from participation after the convention had assembled.[252] But this did not suit the several factions at all. Admittedly, the Prosecution could name the Mayor. Each faction wanted its man named, and while there remained a chance for its man to be named, did not care to see the extraordinary power in the hands of the District Attorney delegated to the uncertainties of a convention.
