The very full reports of the national suffrage conventions, the congressional documents, the files of the _Woman's Journal_ and the _Woman Citizen_ and the newspapers furnished a wealth of material on the general status of the question in the United States. It was, however, the evolution of the movement in the States that gave it national strength and compelled the action by Congress which always was the ultimate goal. The attempt to give the story of every State, in many of which no records had been kept or those which had were lost or destroyed; the difficulty in getting correct dates and proper names upset all calculations on the amount of material and length of time. As a result the time lengthened to three and a half years and the one volume expanded into two, with enough excellent matter eliminated to have made a third. In each of these chapters will be found a complete history of the effort to secure the franchise by means of the State constitution, also the part taken to obtain the Federal Amendment and the action of the Legislature in ratifying this amendment. The accounts of the annual conventions of the National American Suffrage Association demonstrate as nothing else could do the commanding force of that organization, for fifty years the foundation and bulwark of the movement. The hearings before committees of every Congress indicate the never ceasing effort to obtain an amendment to the Federal Constitution and the extracts from the speeches show the logic, the justice and the patriotism of the arguments made in its behalf. The delay of that body in responding will be something for future generations to marvel at. In Chapter XX will be found the full history of this amendment by which all women were enfranchised. In one chapter is a graphic account of the effort for half a century to get a woman suffrage "plank" into the national platforms of the political parties and its success in 1916, with one for the Federal Amendment in 1920. A chapter is devoted to the forming of the National League of Woman Voters after the women of the United States had become a part of the electorate. All questions as to the part taken in the war of 1914-1918 by the women who were working for their enfranchisement are conclusively answered in the chapter on War Service of Organized Suffragists. In one chapter will be found an account of other organizations besides the National American Association that worked to obtain the vote for women and of those that worked against it. A full description is given of the organizing of the International Woman Suffrage Alliance and its congresses in the various cities of Europe.
