The writer is so largely indebted to many scientific writers and authorities that he feels that his labors have been more those of an editor and compiler than of a writer. This observation ap plies especially to that portion of the book dealing with the diseases of the ginseng plant. A cheerful and grateful acknowledgment of these authorities has been made wherever they are quoted.
