198 CULTIVATION. 



the upper part of the bulb transversely, as has 

 been already mentioned. 



Such sorts as do not readily strike from cut- 

 tings are increased by layering, grafting, or bud- 

 ding. Layers are the points of the shoots, in- 

 serted into pots filled with loam, and placed 

 conveniently to receive them ; and, when layered 

 in the usual way (that is, by tonguing or twisting 

 a little the part placed in the soil, and there fixed), 

 are covered with a striking-glass till they make 

 roots, when they may be separated from the 

 parent plants. 



Grafting stove plants is commonly done by 

 " approach." The stocks are raised in pots, for 

 the convenience of placing them near to the 

 shoots with which they are to be enarched. The 

 stock and scion should be nearly of a size : and, 

 at the most convenient point of contact, similar 

 slices of bark and wood are cut from the opposing 

 sides ; these, placed neatly together, are bound 

 and clayed. The clay should be kept moist, 

 which is easily done by bending a wrap of moss 

 round it, and now and then watered.
