Much of the material for this book has been col lected at first hand, from recently printed documents and from manuscripts. A considerable amount of material collected by the Commission on Education of the Edinburgh Missionary Conference, and never printed, is in the author's possession and has been drawn upon. The most modern printed reports of the higher educational institutions and of the mis sionary societies carrying on educational work abroad have been frequently used. A large number of edu cators who are now or who have been closely related to this work have been interrogated. In addition to these sources, the author has been able to draw upon personal experiences growing out of more than twen ty-five years of close relations with higher educational work abroad.
