as ordinary cutting.; as fasi as they fnrtn the third or fourth leaves,
the same as sweet Dot a toes are handled. These cuttings should be
removed close to the tuber or else at the first joint (preferably the
former) ; they are set in sand in a propaga,ting bench with bottom
heat ; when rooted, the plants are handled into stnall pots, where
they will soon forttt tubers. These cutting-plants, if G to 10 inches

method is oftenest cttiplo>~ctl for the purpose of preserving over

grafts are kept growing slowl>y during winter, and cuttings may
