are most useful, for with their aid the powder can be applied 

 to the under side of the leaves more readily. The powder will 

 injure the foliage if left on too long ; twenty-four hours will, 

 as a rule, be found the proper time for it to_ remain, and at the 

 end of that period wash it off with the syringe and clear water, 

 and in a few days afterwards dust the fohage again, if the 

 first application lias not been sufficient to annihilate the fly. 



CHAPTER XXV. 



A EUSTIC PLANT-HOrSE. 



In the garden of our neighbour, J. T. Piekburn, Esq., 

 Stoke IS'ewington, has recently been built a structure com- 

 bining a plant-house and smoking-room, the whole of which is 

 encased in a rockery, as shown in the accompanying figures. 

 The walls consist of a large body of earth enclosed between 

 two facings of brickwork, proper bricks being used on the 

 inner side to accommodate the glass and carpentry, but on the 

 outside rough " burrs," such as are commonly employed for 

 rockeries in the neighbourhood of London, are employed. 

 The whole of these rough walls are planted with ferns, ivies, 

 and hardy succulents, the result being that the walls them- 

 selves constitute a somewhat extensive and eccentric garden. 



The plant-house is lighted by windows in the walls and an 

 elegant lantern roof. The entrance to it from the smoking- 

 room is fantastically decorated with "virgin cork." From 

 this rustic doorway the view of the house is novel and pleasing. 

 The roof is furnished with a number of elegant baskets, well 

 filled with showy plants of suitable character, and the walk is 

 terminated by a fountain, at the back of which is placed a 

 number of pieces of looking-glass, which reflect and re-reflect 

 the splashing of the water. 



The whole of the structure was put up by Mr. Overall, 

 Horticultural Builder, of 16, Shacklewell Lane, Kiugsland.
