perpetuate itself (as bulbs and corms do) by direct off-

Veneer-grafting, That style of grafting in which a cion, with 

 the bark removed from one side, is applied to the side 

 of a stock from which a strip of bark has been removed. 

 Sometimes called side-grafting. Figs. 11 1, 112. 



Watersprout. A strong and comparatively soft shoot arising 

 from an adventitious bud in the top or from the trunk of 

 a plant. It is usually forced out by severe pruning or 

 heading-in. It is an undesirable type of shoot when fruits 

 or flowers are desired, because it e.xpends its energies 

 for one or several seasons in exuberant growth. Water- 

 sprouts are often purposely obtained, however, when it 

 is desired to secure young wood in which to set buds in 

 old trees. Page 105. Compare Sucker. 



Whip-grafting. A style of grafting in which the stock and 

 cion are shaped alike— an oblique cut and a perpendicu- 

 lar cleft ; tongue-grafting. Figs. loi, 102. 



Whistle-budding. That kind of budding in which a ring or 

 girdle of bark is reniox'ed from the stuck, the girdle be- 

 ing filled by a similar ring, with a butl attached, of the 

 variety u Inch it is desired to propagate ; tubular-bud- 

 ding. Page 106.
