Harman Excerpt of document: A mother's love, while demonstrated daily in acts of tenderness and generosity, is always a source of wonder. Who can fathom the quiet thoughts of one who keeps in her heart a constant vigil over the child she has carried in her womb, rocked in her arms, and watched grow, with eyes full of worry, joy, and pride? Her devotion never fails to fill us with gratitude and awe. Today, we honor all those women who, by virtue of giving birth, or through adoption or marriage, are mothers. Each of us should let our mother know that she is ever close in our hearts, and that her many gifts to us are cherished and remembered[OCRerr]not only on Mother's Day, but throughout the year. In recognition of the contributions of all mothers to their families and to the Nation, the Congress, by a joint resolution approved May 8,1914 (38 Stat. 770), has designated the second Sunday in May each year as Mother's Day and requested the President to call for its appropriate observance. IN WITNESS WHEREOF, I have hereunto set my hand this tenth day of May, in the year of our Lord nineteen hundred and eighty-nine, and of the Independence of the United States of America the two hundred and thirteenth.
