THE GREEN-HOUSE. 



universally applicable, and therefore the unexpe- 

 rienced cultivator may consult our catalogue, in which 

 the most successful modes are noticed ; and with quite 

 new plants, of which there may be said to be no 

 experience extant, he must exercise his own saga- 

 city, and find out what is best, by observation and 

 experience. 



For most plants that are propagated by cuttings, 

 the same soil and climate in which the parent plant 

 thrives are allotted ; but some which are very difficult 

 to root are struck in pure sand ; and as to climate, 

 most species strike the readier in one somewhat more 

 moist and warm than that which the parent plant in- 

 habits. Almost all cuttings strike the better for being 

 covered with a bell-glass, which, by stagnating a 

 portion of air round the cutting, renders all aerial 

 changes less felt ; maintains a congenial moisture in 

 the air, which though generally injurious to animals 

 is yet highly favourable to vegetables ; lessens the 

 stimulus of light ; and tends, being in the shade, to 

 maintain an equable temperature. 



The operation of taking off, preparing, and plant- 

 ing cuttings, cannot be commenced, carried on, and 

 completed in a day or two, like that of shifting or 

 potting plants. All sorts do not come into a fit state 

 for having cuttings taken off at the same time : some 

 will be ready earlier, and some later. Whenever a 

 plant appears to be in a proper condition for the pur- 

 pose, it should be proceeded with, and the others left 

 till they are ready.
