There are several organizations who are actively engaged at the present time in supporting or opposing all attempts to enact parcels post legislation. The Postal Progress League, with headquarters at 125 East 23d St., New York City, has for its aim the improvement of our postal service, and is at present actively promoting the cause of the parcels post. This organization is made up of manufacturers, wholesalers, publishers and importers, and is supported by many of the state Granges. The Postal Express Federation is a new organization, formed for the express purpose of urging a reform of our parcels post service, and is supported by many of the same organizations which are back of the Postal Progress League. The American League of Associations (headquarters at Room 343, Rand-McNally Building, Chicago, Ill.), is composed of wholesalers in all lines of merchandise. Its object is to promote the welfare of the small towns and country communities, and to oppose the centralization of population in cities. It is at present actively engaged in fighting the parcels post. These organizations as well as several others, named in the bibliography given elsewhere in this volume, publish and distribute literature for and against the parcels post, and the student of this subject will find it profitable to get into communication with them. Hearings on the subject of a parcels post have been held before the House Committee on the Post-Office and Post Roads, at two different times, in April, 1910, and in June, 1911. At these hearings, have appeared representatives of the associations named in the preceding paragraph and of others who approve or oppose the recommendations for an enlarged parcels post. Among those who have appeared in favor of the parcels post are the various state Granges and farmer’s organizations, the American Dyers and Cleaners Association, the Manufacturing Perfumers Association, the Associated Retailers of St. Louis, the Pennsylvania State Federation of Labor, the Society of American Florists and Ornamental Horticulturists, and the National American Woman’s Suffrage Association. Other societies opposing the parcels post are the National Retail Hardware Association, the United Commercial Travelers, the National Association of Implement and Vehicle Dealers’ Associations, the National Associations of Retail Druggists and Grocers, and various Oil, Paint, and Varnish Clubs and Associations.
