This work is respectfully dedicated T o him the rosarians of America are indebted for the dissemination of much knowledge concerning thc Rose as adapted to American culthre, and its commercial possibilities. To him, also, we are indebted for many varieties resulting froin his ski11 and years of patient labor and experiment in hybridization, among them, Souvenir of Wootten, the first Hybrid Tea Rose raised in America, Marion Dingee, Annie Cook, Mrs. Robert Garrett, BaItirnore, Enchanter, Cardinal, Madonna, My Mary land, and Radiance, some of which have become staples in the underglass. production of Roses for the requirements of the great flower markets. The liberality with which his knowledge, obtained at the expense of countless experiments and failures, has always been placed at thc service of others, has endeared him to all folIowers of his craft, one which, more than any other, demands the acme of patience and self-sacrifice in order to accomplish Iasting results. The lyfe so short, the craft so long to lerne. ACKNOWLEDGMENTS For photographs from which several of our illustrations have been made, we are indebted to Henry A. Dreer, Inc., Philadelphia, Pa. A. N.
