FIXING GOOD TRAITS 19 



unending series of successive divisions to produce 

 an indefinite number of individuals, each precisely 

 like the original because they were in a sense a 

 part of it, my entire series of experiments in de- 

 veloping the new daisy would have been mostly 

 unavailing except for still further selection. But, 

 as the case stands, it was possible rapidly to de- 

 velop an entire race of Shasta daisies by root divi- 

 sion, and thanks to this method the descendants, 

 or, to speak somewhat more accurately, the sisters 

 of the original Shasta daisy have become an enor- 

 mously populous race, scattered to the remotest 

 parts of the earth. 



Several other types of Shasta have been devel- 

 oped by new breeding experiments from the orig- 

 inal stock, but to this day the best races of Shasta 

 daisies must be propagated from the root, and not 

 grown from seed, unless one desires a conglom- 

 erate progeny, departing in many ways from the 

 form and quality of the immediate ancestor. 



FIXING A TYPE 



In all this, it must be recalled, the Shasta daisy 

 does not differ from a large number of long- 

 established cultivated plants that are everywhere 

 recognized as being "fixed" races. 



One does not produce apples or pears or cher- 

 ries or plums or blackberries or potatoes or sugar
