February 1, 1957 Miss Roberts Yerkes Yale University Press New Haven 7, Conn. Dear Miss Yerkes: I am returning the rest of the manuscript. I have rewritten 1) the last paragraph of page 190 including the first line of page 191 as page 190a 2) the pages 123 and 124. (Page 125 is cancelled). 3) the first paragraph of page 258 as page 257a 4) the last paragraph of P. 320 as p. 320a. The old material is sent to you together with the new. Allow me a few observations. a) On page 129 you made some blue pencil marks at the points of suspension which I inserted in the quota- tions from Engels. This is not a matter to treat lightly. These points indicate that intervening words have been omitted. The elimination of them would bring upon me the charge of falsification. Please do not tamper with these and other parts of quotations. b) On page 273 you suggest the substitution of "division into" for "segregation" and you ask "why segre- gation?" My answer is: because the aborigines of America and Australia were segregated from the Europeans. Please see Reader!s Digest of February 1957, pages 35-43. Segre- gation is now taboo in this country. But this must not influence the use of the term where it is indispensable. c) Many of the suggested alterations would convert my text into its opposite. This is especially the case on pages 423-430. For instance: The suggested elimination of "unwittingly" on page 429, 1. 11.
