Fig. 2. The Rose seedlings shown in Fig. 1, four weeks aftergermination, prepared for inarching These methods are inexpensive and, owing to their sim-plicity, may be used by persons without previous experiencein the propagation of plants. By these methods the ever-increasing number of plant breeders will be able to save muchtime in determining the value of hard-wooded plants raisedby means of hybridization. They can be used in manipulat-ing seedlings of rare trees and shrubs intended for crossing,so that each plant will bloom in a much shorter time than ifleft to grow on its own roots. Seedlings of all hard-woodedplants resulting from collections made by travelers in foreign THE SEEDLING-INARCH 53 countries may thus be brought to the flowering stage and theirvalue determined quickly. The most remarkable feature of the new methods lies notonly in their simplicity but also in the certainty of the unionswhich result. The writer has had very few unsuccessfulunions and none among those cla
