The Brazilian Green Book. Authorized English Version, with Notes by
Andrew Boyle. (Allen and Unwin. 7s. 6d. net.)— Brazil's reasons for entering the war are clearly set forth in this volume of diplomatic papers, which deserves attention. She was driven from her neutrality in June, 1917, and finally compelled to declare war in October, 1917, by Germany's reckless and illegal submarine campaign, in which neutrals and belligerents suffered alike. But she was influenced also, like nearly all the Central and South American States except Chile, Argentina, and Venezuela, by a desire to maintain the solidarity of America in foreign policy and to co-operate with the United States. The despatch of July 4th, 1917, setting forth this policy of " American fraternity "- the counterpart of the Monroe Doctrine—is of great importance. United America can and will frustrate any German schemes of colonization in Southern Brazil or elsewhere.
