FEBRUARY.] HOT-HOUSE SHIFTING PLANTS. 35 



they are summoning all their forces, and no profession 

 has more than that of the Horticulturist. Let a strict 

 examination be made about the end of the month 

 for the Red spider; they will be in operation some weeks 

 before their depredations are observed on the foliage. 

 The under side of the leaf is their resort in the first in- 

 stance, and on such plants as have been already men- 

 tioned. 



Observe daily the young shoots, in case the Green fly 

 becomes numerous. They give the foliage a very dis- 

 agreeable appearance, and with most people it is intole- 

 rable, before their career is arrested. It also takes a 

 stronger fumigation, which has frequently to be repeat- 

 ed the following day to J;he same degree, much to the 

 injury of many of the plants, and adding to the disa- 

 greeableness of the continued vapour in the house. 



OF SHIFTING PLANTS. 



The Calceolarias that were put in small pots about 

 the beginning or middle of last month, will, if they 

 have done well, require, about the end of this, to be 

 put in pots a size larger. 



If any of Lilium longiflorum, Specibsum, or Japonicum, 

 are wanted to flower early, and were put in the Hot- 

 house in December, without dividing, those that are to 

 flower will have pushed their flower stems, and can be 

 separated from those that will not flower, and put 

 singly into pots ; the two former into five or six inch 

 pots, while the latter require six or seven inch pots.
