I have been strongly impressed by the joy of life animating these young girls and expanding on every occasion, like that of one of my visit. If the ceremonies of the reception were performed in a nearly military order, a spontaneity of youth and happiness expressed itself in the songs of greeting composed by the students, in the smiling and excited faces, and in the rushing over the lawns to greet me at my arrival. This was indeed a charming impression which I could not forget. Back in New York, several ceremonies awaited me before my leaving for Washington. A luncheon of the Chemists, a reception at the Museum of Natural History and the Mineralogical Club, a dinner at the Institute of Social Sciences, and a great meeting at Carnegie Hall, where many delegations represented the faculties and students of women's colleges and universities. At all these receptions I was greeted in warm addresses by prominent men and women, and I received honors very precious to me because of the sincerity of the givers. Neither has the part of national friendships been forgotten; the address of Vice-President Coolidge was a noble recognition of the past where French and Polish citizens have been helpful to the young American Republic, and is also a statement of fraternity strengthened by the tempest of the last years. It was in this atmosphere of affection created by the convergence of intellectual and social sympathies that there took place on May 20th the beautiful ceremony at the White House. It was a deeply moving ceremony in all its simplicity, occurring before a democratic gathering including the President and Mrs. Harding, cabinet officers, Judges of the Supreme Court, high officers of Army and Navy, foreign diplomats, representatives of women's clubs and societies, and prominent citizens of Washington and other cities. It comprised a short presentation by the French ambassador, M. Jusserand, a speech by Mrs. Meloney for the American women, the address of President Harding, a few words of gratitude said by me, a defile of the guests, and a group picture for a souvenir, all this in the admirable setting of the White House, peaceful and dignified, white indeed between its green lawns with wide prospects on that beautiful afternoon of May. A remembrance never to be forgotten was left by this reception in which the chief representative of a great nation offered me homage of infinite value, the testimonial of the recognition of his country's citizens. The address of the President had been inspired by the same sentiments as that of Vice-President Coolidge, as far as concerned his appreciation of France and Poland. This address gave also an expression of the American feeling which was emphasized by an exceptional solemnity in the delivering of the gift. [Illustration: _Copyright International._ Mme.
