a very large head. They were somewhat less dark 

 in color than the parent stock. 



My work with the turnip has not extended 

 beyond the stage of experimental crossing with the 

 cabbages, which led to no prospect of useful 

 results. With the radish, which might be described 

 as a dwarf turnip, my work has been carried 

 along the line of selection, without hybridizing. 



There are enough variations among the seed- 

 lings of any given root to afford ample opportunity 

 for selection as to form, color, and qualities in 

 general. 



In the course of the experiments a dozen or 

 more of the most popular kinds of radish were 

 used, the principal aim being to get the roots very 

 uniform and smooth, all developing at the same 

 time, instead of at different times as most radishes 

 now do; and all of uniform color. 



Another object was to develop varieties with 

 the smallest amount of foliage that would be 

 adequate to build up the roots quickly under good 

 conditions. 



I also gave attention at one time to the flavor 

 of the radish, developing the sweet pungency for 

 which the vegetable is relished. 



As just noted, all the radish seed used in these 

 experiments proved exceedingly variable; and 

 even those that were selected and re-selected per-
