readily clone, as they are for the most part found round the 

 outside of the ball. These troublesome creatures can, how- 

 ever, be expelled (as stated in the Flower Garden) by water- 

 ing the mould in the pots with water into which unslacked 

 lime has been put. The caustic property of the lime will 

 bring them up to the surface, when they may be picked up 

 atnd carried away. 



All plants that are infested with insects, should be com- 

 pletely cleaned before they be taken into the house ; but at 

 this season, this will not often be the case if the plants have 

 been properly managed during the summer, as their rapid and 

 free growth will in most cases be a preventive. The scaly 

 insects will, even on very healthy plants, particularly cori- 

 aceous-leaved ones, be met with, and they should be washed 

 off with a sponge, or soft brush, and soap and water. Those 

 plants which are sickly or ill-grown should be thrown away, 

 if duplicates of them have been propagated ; it is the height of 

 folly to keep diseased or mis-shapen plants in any collection 

 when they are so easily propagated. When a regular system 

 of propagating is annually adopted, and all good cultivators 

 follow that practice, a certain part of the stock will of neces- 

 sity be to be disposed of, as in the end, no houses of reason- 

 able dimensions would otherwise hold them ; and as this is 

 the case, all that are worn out, ill grown, or sickly, should 

 be selected and destroyed. Almost all green-house plants 

 flower and look best when young, and the cultivator who does 

 not renew his plants to a considerable extent annually, will 

 never gain much credit by his collection. 



ARRANGING PLANTS IN GREEN-HOUSES. 



The instructions which were given on the subject of ar- 

 ranging green-house plants, when set out in the early part of 

 the summer, are to be applied here also ; but as the whole 

 collection is generally contained in one or two houses at most, 

 a more general effect may be produced. As the season of the 

 tender annuals, which has occupied the stages of the green- 

 houses for the last three months, will be now past, they of
