Luther Burbank, his methods and discoveries and their practical application; prepared from his original field notes covering more than 100,000 experiments made during forty years devoted to plant improvement . with 0 and L andthe rest—it is obvious that each new test wouldfind you with a smaller number of letters fromwhich to select, and hence with an increasingprobability of successful selection. When, finally, there remained only two lettersin the bag, your chance of securing the right onein the first draw would obviously be an even when only the final N remains, you couldmake no mistake — your selection of the rightletter then becomes a certainty. Now I make this illustration because I thinkit has peculiar application to the case of the plantdeveloper. His method is not unlike the methodof selection just suggested. As the result of hisfirst hybridizations, he does not dare to hope thathe will secure the exact combination of qualitieshe would like to see aggregated in his ideal fruitor flower. But by having a large number ofseedlings from which to select he may reasonablyhope to secure one that will present some one atleast of the desired qualities in superlative degree.

And as the plant developer continues hisexperiment with successive hybridizings andsuccessive selections, he will be able in latergenerations to find individual seedlings thatcombine successively more and more of thequalities he is seeking.
