A note written on a small piece of paper sent by Gertrud Schoenberg to Ives after the death of her husband. Reads “preserve one’s self esteem and to learn.” Initial printing incorrectly read as: “preserve one's self and to learn.” It first appeared in print in Henry and Sid-ney Cowell, Charles Ives and His Music as a footnote with lines 6-7 incorrectly reading: Initial misinterpretation was probably due to cursory reading of Schoenberg's problematic handwriting. Reprint Second Edition A repro-duction of Schoenberg's note and the correct wording is given on the following page of the present volume. [The original is held in the Ives Papers at Yale University.]
