Hybrid Oak Information

Mr. Thomas Q. Mitchell, 16 East 48th Street, New York 17, New York, calls our attention to his article on "Hybrid Oak Crop Trees," in Harper's Magazine for February, 1948. He adds: "A much longer article is in preparation (in collaboration with Mr. Charles Morrow Wilson) for Scientific Monthly. Can you report any hybrid or exotic oaks there, or put me in touch with any Dendrophiles interested in oak hybrids as crop trees?"
