sliould be anchored with pebbles or clods of earth to 

 prevent whipping about by wind. Idiis is especially 

 important where the ground is hard and dry. Since this 

 method is the only one practiced in jjropagating l)lack 

 raspberries, it is sometimes called tih hiycriiuj. In the fol- 

 lowing spring the rooted tips are severed for planting 

 with about six inches of the stems to serve as handles. 



The buds from which the new 

 canes are to develop must nrit be 

 set deeper than the surface of the

Since the buds on must plants will nut de\'elop into shoots 

 if buried, only a few plants are adapted to this form of 

 layering, among them red osier, willow, high bush cran- 

 berr)' and snowball. 



99. Modified continuous layering, popular in propagat- 

 ing varieties and species of grapes and other vines that 

 do not root readily from cuttings, is practiced as fol- 

 lows: In spring new canes are laid in open trenches 

 two or three inches deep and pegged down. \\'hen the 

 buds have developed shoots, the opposite sides of the 

 parent canes are wounded at the nodes and earth is 

 drawn over the canes and the bases of the shoots. After
