Samuel Eliot Morison '08, Jonathan Trumbull Professor of American History, yesterday accepted full responsibility for so-called anti-Negro sentiments in his book, the second volume of "The Growth of the American Republic." But he branded charges that the book is anti-Negro as "frivolous," and plans no changes in the text, which has been on the market for over 20 years.

Supposedly written in collaboration with Professor Henry S. Commager of Columbia, the book was attacked for its use of such phrases as "sambo" and "blacks."

Objections that these phrases slurred the American Negro were raised by the National Association for the Advancement of Colored Peoples.
