In order to prevent any disagreeable incidents from marring the Class Day festivities it is essential that all purchasers of Class Day tickets should remember that tickets are not transferable. In the past, notwithstanding determined efforts on the part of the Class Day Committee, tickets have found their way into the hands of persons whose presence was not only undesirable, but objectionable. So long as the tickets are in the hands of Harvard men or their friends, the holders feel it their duty to use them according to the conditions under which they are purchased. How ever, once a ticket is sold or given away carelessly, this sense of obligation ceases, and incidents may occur to mar the harmony of the day. In order to make Class Day a complete succss, all who have purchased tickets should co-operate with the Class Day Committee by adhering strictly to the conditions under which they are purchased.
