ADVENTITIOUS BUDS. 173 



of buds, like that of roots, is very often consequent on 

 decay or injury. The Dutch bulb-growers have availed 

 themselves of this latter circumstance in the propa- 

 gation of hyacinths. Mr. Fortune, who pubUshed 

 some articles on this subject in the * Gardener's 

 Chronicle,'^ describes two special modes as adopted by 

 these skilful horticulturists the one to make two or 

 three deep cuts at the base of the bulb, destroying the 

 nascent flower-stalk when, after a time, small bulbs are 

 formed along the edges of the cut surfaces (figs. 84, 

 85). The other method is effected by scooping out 

 the interior of the base of the bulb, thus leaving ex- 

 posed the cut ends of the sheathing leaves arranged 

 concentrically; along these lines the new bulbs are, 

 after some time, formed in great numbers (fig. 86).
