ed, stem, branch, and leaf, with soap and soft wa- 

 ter ; using a bit of woollen rag tied on a small stick, 

 and observing to wash or rub well into every angle 

 of the stem and branches. If any of the plants 

 have been trained to sticks or poles, these should 

 either be completely washed, as above, or be new 

 painted ; and in dressing the plants to them again, 

 observe to tie with fresh worsted or matting : for 

 the eggs and larvae of the insects are as apt to be 

 lodged on these, as on the foliage or branches. 

 Every plant, when it has been gone over with the 

 soap-suds, should be well syringed with pure water, 

 or otherwise be washed quite clean, in order to pre- 

 vent the accumulation of dirt on the leaves, which 

 would else be encouraged, on account of the glu- 

 tinous nature of the soap. 



Other plants, of softer, downy foliage, as gera- 

 niums, ononis, phlomis, &c. are subject to the at- 

 tacks of the green-fly. Such should, therefore, if 

 affected by that insect, be placed in a hot-bed frame, 

 &c. (they may be placed upright, or be laid on their 

 sides) in a compact manner, where let them be fu- 

 migated for half an hour with tobacco. The frame 

 should be well matted up, or be covered with an 

 oil-cloth, in order to prevent the smoke from es- 

 caping, as much as possible. After the plants have 

 remained here an hour, they should be well syringed, 

 to clean them of dust collected in winter, and of the 

 dead insects. Then shake them well, in order to 

 prevent the water from lodging on their leaves, and 

 to prevent the bad effects of damp, which otherwise 

 might hurt them at this early period. Replace them
