Cyclopedia of American horticulture, comprising suggestions for cultivation of horticultural plants, descriptions of the species of fruits, vegetables, flowers, and ornamental plants sold in the United States and Canada, together with geographical and biographical sketches. Gardening. 2062. French Breakfast and Olive-shaped Radishes, two of the early or spring Rad- ish class iXH). that case the root soon deteriorates into a small, slen- der, woody and more or less fibrous member. It has been thought by some that the Radish is only a modi- fied form of the wild charlock, or Raphantis Maphanistruni. In fact, experiments ^yere made on the charlock by Carri^re, who was able in a few years to prodiice edible Radishes from the wild plant. While these investigations seem to be con- clusive that the Radish can be produced from the charlock, they nevertheless do not prove that sxich was the actual origin of the garden Radish. DeCan- dolle, whilst accepting Car- riere's experiments, was unable to understand how the Rad- ishes of India, China and Japan could have originated from the charlock, since that plant is un- known in those countries and the Ratlish has been grown there for centtxries. It is pos- sible that the Radish was car- ried eastward from western Asia and Europe, but such has not been the general course of the migration ot plants. It is possible that the Radishes of the Orient are a different species from those in Europe, although they are generally regarded as the same spe- cies. See Btvphanus. The experiments of E. A. Carrifere with the wild Rad- ish (.lonrn. d'Agric. Prat., 18()9, also separately printed) form a classical example of the possibilities of plant- breeding. In five years by means of cultivation and selection alone he was able to produce from a trouble- some weed pi-actically all the important type-forms of Radish in cultivation. Carriere began by gathering seeds of the wild Eaphanus MiiphuiiUtrvm (Fig. 2003), which he collected as far as possibl
