Plant-breeding; comments on the experiments of Nilsson and Burbank . -tivated in Cahfornia, where the culture of potatoes forcattle feeding or for factories is of hardly any tubers are of a large and (what is more important)almost uniform size. The evidence which is set forth in this discussion, 1gathered mainly during my visits to the Santa Rosa andSebastopol farms of Burbank, where he was so kind as toexplain his cultures to me and to answer all my cjuestionsabout them. I visited him twice during the summer of1904, and had the privilege of a four-days intercourse withhim in July, 1906. Of course, I had prepared myself forthese \isits by studying the magazine articles on his workpubHshed during the last few years, and among whichthose of E. J. Wickson in Sunset ^Magazine may be cited asthe most complete and the most reUable. Wherever pos-sible, however, I submitted the statements once more to mvhost, asking him such questions about them as would meetthe doubts which might offer themselves from the standpoint o • • 1-1 1-r ;-» ? n. i6s 166 PLANT-BREEDING of a biologist. As a rule, the answers covered my wishesand led to the conclusion that notwithstanding the widelydivergent, and on some points quite opposite, methods themain results of practice and science are the same. In order to understand the kind of evidence which willbe discussed here, it is necessary to have a clear idea of whata visitor can see on the farms. As soon as Mr. Burbank hasoriginated a new kind of useful or ornamental tree, flower,fruit, or vegetable, he sells it to one of the great seedsmen,florists, and nurserymen with whom he is in constant relation-sliip. They take the whole stock, multiply it and offer itto the trade. They buy the exclusive right of selling thenew variety, and nothing of it is left on the farms of it follows that a visitor cannot expect to have a sur-vey of the achievements that have already been made.
