[9] In this statement, Professor Brentano re-enforces the opinions of the American economist to whose teachings and writings the "progressive" movement in American economics and politics, and especially the movement for conservation of natural resources, must be traced. For many years Professor Richard T. Ely has been pointing the way to this conservative "socialization" of our natural wealth. APPENDIX I. BIBLIOGRAPHY The following list of the principal works consulted in the preparation of this volume may serve also as a bibliography on the subject. There are very few American books in the list, because the object of this volume is to summarize the European situation. For the spirit of the movement the student must consult the contemporary literature of Socialism--the newspapers, magazines, and pamphlets, and the campaign documents that flow in a constant stream from the Socialist press. These are, of course, too numerous and too fluctuating in character to be catalogued. Lists of these publications can be secured at the following addresses: The Fabian Society, 3 Clements Inn, Strand, London, W.C. The Labor Party, 28 Victoria Street, Westminster, London, S.W.
