 During this period, Cattell gave a large part of his time to the duties devolving on him in this connection, and during 1915–16 he devoted himself almost entirely to this work.Being responsible for the organization and general management of the office of the Congress during these years, he gave his best thought and energy to the manifold requirements of the work, with special reference to all matters connected with general organization, with publicity, and with the collection and handling of funds.The publications of the Congress include a volume of general proceedings, with a history of the organization and development of the Congress from its initial inception to its final distribution of printed volumes of proceedings.
