BUSY,  NEW  INVOKES  RADIO  IN  CAMPAIGN

FIRST USE AS POLITICAL AID

Seated  in  Office  at  Capitol,  Hoosier  Lauds  Administration  to  Big  Women's  Gathering.

    Senator Harry S. New, of Indiana, sitting in his office at the Capitol, last night addressed a large audience of women in Tomlinson hall, in his home city of Indianapolis. This, probably, is the first application of the wireless telephone to a political campaign and it was fitting that a progressive statesman such as the Republican senator from Indiana should inaugurate it. Senator New was the first member of the upper house of Congress to test out a flying machine, and as private citizen and statesman, he has consistently been in the front aiding the development of those things which will benefit the people of the country.

Duty  Keeps  Him  in  Capital.

    Recently there was formed in Indianapolis a women's organization known as "The New for Senator Club." A monster mass meeting was arranged for last night in the great hall in which President Harding spoke during the campaign, and Senator New expected to be present in person. Then came the consideration of the treaties negotiated by the arms conference and Senator New felt it his duty to remain here and hold up the hands of the President.
    The wireless suggested itself, and last night's address was the result the senator was at his desk in the Senate office building, and the words he spoke were broadcasted from the Anacostia naval air station. The call "N O F" went out a few seconds before 10 o'clock, Washington time, and on the stroke of the hour, the words of Senator New began to be heard in his home city.

Welcomes  Women  In  Politics.

    Senator New said, in part:
    "I welcome the participation of women in our political affairs. I approve of it, first, because I believe it the duty of every citizen to interest himself in the administration of government, and I find an added reason for approval in the unquestioned fact that the ideals of women are the highest and best.
    "I believe that there is nothing more dear to the heart of American women than the guarantee of a country at peace, and I know further that this administration has given us that guarantee, as nearly as human power permits. The world is to be felicitated on the outcome of the great disarmament conference, the accomplishments of which were far beyond the fondest expectation of those by whom it was called.

Lauds  Administration  Record.

    "There are voices of public men and near-public men that have never yet been raised in support of the work of the conference or the effort for peace being made by this administration, but at neither end of the war nor the events that have grown out of it have I stood mute. With the prospect of peace and prosperity ahead, I hope to find the task of a senator no more difficult than it has been in the five years that have elapsed since you first honored me with your commission."
