This report treats in detail of the tariff policies of the colonial powers and of the self-governing Dominions of the British Empire. Part 1 contains chapters on tariffs and tariff policies in the colonies of Belgium, France, Germany, Great Britain (Crown Colonies and India), Italy, Japan, the Netherlands, Portugal, Spain, and the United States, with some general descriptive and historical matter. The tables of contents prefixed to each chapter, and the general index will enable the reader readily to locate the discussion of any phase of the subject in which he may be especially interested. Part II sets forth the development of the preferential tariff policy in the British Empire, with chapters on Great Britain, Canada, Australia, New Zealand, South Africa, and Newfoundland. A large part of the Introduction and Summary is based upon the material contained in other chapters, but it begins with an outline of the rise of modern colonial empires. After establishing to necessary distinctions between the different kinds of colonies, it discusses the characteristics and importance of colonial trade. The summaries of the other chapters of the report include brief statements of the general policy of each of the colonial powers, but the survey of colonial tariff policies is mainly developed subject by subject. In the sections of the Introduction and Summary devoted to treaty obligations, import duties, export duties, intercolonial trade, the treatment of colonial products in the market of the mother country, and minor and concealed preferences the reader will find a general presentation of those topics. It is felt that the material presented in this chapter will be sufficient to introduce the subject, and it has been published separately under the title Introductory Survey of Colonial Tariff Policies, which may be obtained from the Government Printing Office for 10 cents a copy.
