The idea was that the gift would come exclusively from the American women. A committee including several prominent women and distinguished scientific men received some important gifts, and made an appeal for a public subscription, to which a great number of women's organizations, especially colleges and clubs, responded. In many cases gifts came from persons who had experienced the benefit of radiumtherapy. In this way was collected the "Marie Curie Radium Fund" of more than one hundred thousand dollars for the purchase of a gramme of radium. The President of the United States, Mr. Harding, kindly agreed to deliver the gift in a ceremony at the White House. The Committee invited me and my daughters to the United States in May, and even though it was not vacation time for me, I accepted the invitation with the consent of the University of Paris. All care of the voyage was taken away from me. Mrs. Meloney came to France in time to be present at a manifestation organized on the 28th of April in favor of the Radium Institute of Paris by the magazine _Je Sais Tout_, and accompanied by sincere expressions of sympathy for the American nation. On May 4th, we took passage at Cherbourg on the _Olympic_ for New York. The program of my voyage prepared by the Committee seemed very intimidating. It was announced that I would not only attend the ceremony at the White House, but also visit many universities and colleges in several towns. Some of these institutions had contributed to the Fund; all desired to offer me honors. The vitality and the activity of the American nation produces programs on a large scale. On the other hand, the wideness of the country has developed in American citizens the custom of long travel. But during all that travel I was protected with the greatest care, in order to lighten as far as possible the inevitable fatigue of the voyage and the receptions. America not only gave me a generous welcome, but also true friends whom I could not thank enough for their kindness and their devotion. After having admired the grand view of the harbors of New York, and having been greeted by groups of students, Girl Scouts, and Polish delegates, and welcomed by many gifts of flowers, we took possession of a peaceful apartment in town. The following day I made the acquaintance of the Reception Committee at a luncheon given by Mrs. Carnegie in her beautiful home still filled with memories of her husband, Andrew Carnegie, whose philanthropic achievements are well known in France. The following day we went for a visit of a few days to Smith College, and Vassar College, a few hours from New York. Later I also visited the colleges of Bryn Mawr and Wellesley, and I saw some others on my way.
