usually put in sand first, and as soon as they begin to form 

 roots, are taken out and potted in light compost. This is not 

 always necessary, especially in summer time, when quick- 

 rooting cuttings may be put singly in small pots in proper 

 compost, and will at once make plants and occasion very little 

 trouble. It may always be known when cuttings are throwing 

 out roots, as their tops become greener, and begin to grow 

 simultaneously with the emission of roots from the base. 

 Then they should have a little more air and light to prepare 

 them for the life they are to lead as independent plants. A 

 cheap propagating frame may be extemporised by fitting 

 together two flower-pots and filling the space between them 

 with moss or sand, and then fitting a bell-glass over. This 

 plan answers well for hard-wooded plants, which are very slow 

 in making roots, and are apt therefore to be neglected, and, 

 perhaps, occasionally forgotten. 



The multiplication of stemless plants, such as the cineraria 

 and primula, is accomplished by division of the root where 

 named varieties are required, but when the cultivator has no
