budded, like peaches. The pecan and other hickories 

 will also grow from cuttings of the ends of the soft grow-

 common geraniums, for conservatory use, should be re- 

 newed from cuttings every year. The fancy or show gera-

 will not come true. Geraniums can also be grafted. (See 

 page 130, herbaceous grafting.)
