The author acknowledges credit to all who, through their wide experience, have written Of plant propagation, and especially to Joseph Meehan* and George W. Oliver,* both pre-eminent in their fields of nursery and greenhouse propagation. Credit is due Dr. L. H. Bailey for crystallizing the scattered information and publishing it in the Nursery Book of 1891. The author welcomes suggestions and advice relating to the subject matter of this book to the end that when a new edition becomes necessary it may have increased value.
