W. H. HonCE B. Y. Morrison An Editorial Comment This issue of The American Horticultural Magazine appears without a desig nated Editor- Benjamin Y. Monison has retired from this position, one he has held f01' 37 yean. This decision was made, s'urely with reluctance, on the part of Mr. Nlorrison, and much to the regret of those who have been close to the l\1agazine for any length of time. Somewhere "along the line" one has to break with his elected responsibilities in order to devote time to more cherished tasks. B. Y. Nlorrison, H orticulturist, may now contend with the problems (which are really 1J leasures) of everyday gardening, except for the notes and occasional m"ticles he has promised to contimoe writing for the Magazine. During the years of his leadeTShip, NIT. Morrison has maintained The Ameri can H orticultural Magazine at a level of quality and distinctiveness of char acter that gives our Magazine an enviable status among the gardening maga zines of the World-and The American H Ol"ticultural Magazine is world re nowned. If one is fOl"tunate to have a complete set of the Magazine, he will find that the bl"eadth and p1"Ofundity of wTitings contained are without comparison. Cer tainly if the vast an-ay of horticultural hnowledge accumulated in The Ameri can H ol·ticultural Magazine during these "M on-ison-years" were assembled in a volume, it would be a library treasure. I t can be noted here that Mr. Morrison has been the only designated Editor of the American (National) H orticultural Magazine since Volume 5.* T he AmeTican H orticultural Magazine has l"emained without the necessity pf deviation from its em"liest concept- a scholarly presentation of original horti cultural contributions directed to the interests of the serious amateur.
