March 13, 1914 Dr. L. H. Pammel Iowa State College, Ames, Iowa. My dear Prof. Pammel: I wish to say that I have received copy of The Weed Flora of Iowa, No. 4. I am really amazed to note what a splendid work it is. I have been reading about it for some time, but had no idea that it is such a splendid contribution to this most important subject. If possible it makes me feel prouder than ever to know that I received my training under such an accomplished authority. Trusting that you, Mrs. Pammel, and the children are well and that all goes well with you, I am, Yours most sincerely, G. W. Carver Director Dept. of Research & Experiment Station
