almost all other plants propagated by such means. 

 A large portion of air, if it can be applied with- 

 out light, seems necessary to excite the production 

 of roots : thus cuttings, in immediate contact 

 with the sides or bottom of striking pots, as 

 well as near the surface, strike root more readily 

 than if placed out of the reach or immediate 

 action of the air. Precaution, however, is neces- 

 sary, lest drought assail the delicate fibres so near 

 its influence ; to guard against which, moderate 

 waterings and shading must be had recourse to. 

 In piping and layering carnations, there are 

 several minor circumstances which should be 

 mentioned in this place. Professional florists 

 raise their pipings on a hot-bed, which, when of 

 proper heat, is covered with suitable compost, on 

 which the striking-glasses are set, and filled with 

 pipings not too close together. Here they are 

 nursed, and from hence they are potted off as 

 soon as they advance in growth. This is a great 

 advantage, because the growth of pipings is 

 unequal; and according to their advancement 

 should they be treated in respect of the supply
