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.
