A Service Bureau of the Committee at a centrally located office in Washington provided information as to the officials, the function and the location of all Government departments and similar matters. In the rapid expansion of all these departments, the creation of new agencies and the overcrowded condition of the capital, due to the thousands of men and women pouring into and going through the city, it saved for all these people many hours and much energy. The inquiries that came to it by personal appeal, by telephone, and by mail mounted to an average of many hundreds daily. In addition to the news matter which it distributed at home and abroad, the Committee on Public Information sent out an official bulletin which, with a circulation of more than 100,000, gave information concerning all governmental affairs and activities in connection with the war; prepared special articles concerning all phases of the war progress of the nation which were widely published in the Saturday and Sunday magazine sections of newspapers; and published several series of pamphlets, written by authorities upon the questions discussed, which set forth the reasons for our participation in the war, exposed the pretensions of Germany and dealt with other important matters. These pamphlets also had a wide circulation and were especially useful for the hundreds of public speakers who talked to assemblages of people in mines, factories, ship-yards, theaters and other public places. They were intended to give information to all who wanted it and to furnish ammunition for the determined battle the Committee was waging to win the attention and rouse the feeling of a polyglot nation, huge numbers of whose people had not hitherto acquired much knowledge of or developed much interest in their adopted country. For all this work several hundreds of authors, newspaper and magazine writers, publicists, university professors and others either gave their time and labor freely or took for their services an amount of pay that barely paid their living expenses, and, for the rest, were repaid by the satisfaction of doing something to aid the needs of their country. An organization of speakers called “Four-Minute Men,” working under the Committee, had a membership of 35,000 and gave short, incisive talks in five or six thousand communities, speaking at motion picture theaters, at factories during the noon hour, at country churches and school houses, at assemblages of every sort. The campaigns in which they took part embraced work for the Red Cross, the welfare organizations. Liberty loans, savings stamps, against German propaganda, and every kind of activity for the winning of the war that the nation engaged in. A bulletin for the use of the Four-Minute Men was prepared by the Committee’s experts for each campaign, giving material for their suggestion and guidance.
