ADVENTITIOUS BUDS. 173 
of buds, like that of roots, is very often consequent on 
decay or injury. he Dutch bulb-growers have availed 
themselves of this latter circumstance in the propa- 
gation of hyacinths. Mr. Fortune, who published 
some articles on this subject in» the ‘ Gardener’s 
Chronicle,’ describes two special modes as adopted by 
these skilful horticuiturists—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).
