The meeting at Tokyo, like earlier world power conferences in Europe, was literally a world-wide affair, with almost 300 organizations participating and about 700 foreign members and 3,000 Japanese attending.

Notes on Governmental Economy

THE halcyon days are over. Years when every Treasury estimate of governmental finance, however roseate, proved to have been conservative have given way to years in which the federal deficit gathers momentum like a snowball and finally has to be measured in ten figures.
