(Vol. VII, p. 182-184) The Practical Essentials of Hand PoUenizing (Seepages 5-6), gives the details of the simple, yet practical,methods by which hybridizing is accomplished. The dia-gram below shows the construction of the geranium, andshould be of further assistance in your work. It remainsonly for you to apply these methods to the geraniums youhave chosen for your (A) Inflorescence of a geranium;open flower on left showing con-dition with mature anthers andimmature pistil; open flower onright showing condition withmature pistil and faded (de-funct) anthers. (B) Stamens and pistil from left-hand flower, enlarged. (C) Pistil with stamens removed,enlarged. (D) Mature stamen, enlarged. (E) Mature pistil showing ovary, al- ways included in stamen-tube,style, and radiating stigmas,enlarged. Few plants among all the popular favorites havegreater merits than the geraniums, and none per-haps offers better opportunities for interestingexperiments that may be made by the amateur. ^Luther BtrRBANK. Old Trees Made Young TT 7HAT kind of a tree is that? asks a neighbor, as he W leans over the fence. Why, it is hardly fair tospeak of that as a tree; that is a concentrated, double-barreled prune experiment. If I were to name all the vari-eties of fruit that are growing on the branches from thatsingle trunk, it would sound lik
