Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It appears that Mr. Charles W. Gould, a clear, vigorous, fearless thinker on problems of race characteristics, amal gamation of peoples and immigration, raised perplexing questions which drove Mr. Brigham to his careful and critical re-examination, analysis, and discussion of army data concerning the relations of intelligence to nativity and length of residence in the United States. In a recently published book, America, A Family Matter, to which this little book is a companion volume, Mr. Gould has pointed the lessons of history for our nation and-has argued strongly for pure-bred races.
