30 PLANT PROPAGATION 
two, with the holes in the bottom sufficiently enlarged to 
allow the stems of the subjects under treatment to pass 
through, may be used. The stems are then tongued, 
ringed, or notched at the place where roots are desired. 
The two halves of the flower-pots or boxes are then put 
in position and tied together, and supported by props or 
the best measis available. The pots are filled with com- 
post and kept moist by a covering of moss or straw 
bands, and syringed daily to induce roots toform. When 
sufficiently advanced, a partial incision is made in the 
stem below the receptacle, and gradually increased day 
by day. When sufficient roots have formed to support 
-the top the lower stem is entirely removed and the 
renovated plant kept in a close, moist atmosphere with 
shade from sunshine until completely re-established. 
Serpentine Arching. 
This plan answers very well for creepers and trailing 
subjects with long, firm shoots, such as Aristolochias, 
Wistarias, and Rubus, as several plants can be reared 
from one long branch. ‘The shoot is bent down to the 
ground, tongued or notched under the joints to be buried, 
pegged down, and covered with soil. The intervening 
spaces are curved in loops above the ground, each loop 
bearing either a branch or a growing bud. When well 
rooted the stems are severed and the resulting plants 
transplanted to the positions they are intended to 
occupy. 
Growing-Point. 
A method of layering which sometimes occurs naturally 
with the Common Blackberry, and may be utilised with 
advantage for rearing scarce varieties of Gooseberries,
