October 2, 1926 Dr. L. H. Pammel Department of Botany Iowa State College Ames, Iowa My dear Dr. Pammel: I wish to thank you for your favor of recent date. I assure you that it is always a pleasure to receive your message. Please give me the name of the Professor of Plant Pathology. I spoke to his class when there, but I have forgotten his name. He knows you and said that he had attended Ames at one time, and I think he was in one of your classes. He is the man who showed me so many fine specimens of the perfect stage of the brown rock of the peach. With sincerely good wishes, I am Yours very truly G. W. Carver.
