extent and it was also possible to study carefully the individual 

 dilferences of each. Variation was observed in the following 

 characters : height of plant as tall or dwarf ; erect or spreading 

 habit ; fine or coarse stems ; scant or dense foliage ; wide or nar- 

 row leaves; color of stems, heads, and leaves; slendei-, short, 

 blunt, cylindrical, or nodding heads ; date of maturity ; length 

 of blooming period; amount of aftergrowth, rust resistance, and 

 the like. (See Figs. 598 to 602 inclusive.)

In order to study these variations more carefully, selected 

 plants were propagated vegetatively by cuttings or slips of the 

 bulbs formed in the stool ing. In this manner a large niimber 

 of plants can be obtained, which are in reality transplanted parts 

 of the same individual. It is possible that bud variation may 

 occur among these cuttings from the same plant and experiments
