CIRCUMPOSITION differs from layering, 

 only that in this the shoot to be rooted 

 is bent down to the soil, whilst in cir- 

 composition the soil is placed in a vessel 

 and raised to the shoot. There are pots 

 called layering pots made for this prac- 

 tice, and differing from the common 

 garden, pot, only by having a section 

 about an inch broad cut through one 

 side, and to the centre of the bottom, for 

 the admission of the shoot or branch. 

 Moisture necessary for favouring the 

 emission of roots is supplied by means of 

 a bottle, from which the bottom is struck 

 off, and the neck furnished with a cork, 

 perforated so as to admit a small pigeon's 

 feather or bit of wool to form a syphon, 

 by means of which the moss is kept in a 

 proper state of moisture. Hardwooded 

 plants are propagated in this way trom 

 the middle of May till the end of June ; 

 and the branches are sufficiently rooted 

 to be taken off by the end of September. 

 It is, however, necessary in all cases, to 

 ascertain whether the branches are suffi- 

 ciently rooted previously to their being 

 separated. After being separated, the 

 rooted branch is treated like one layered.
