 here the drainage must first be put in to the depth of nine or 

 ten inches, and this must be covered with turves of grass to

 object for which it was put in. In the case of such plants 

 it becomes impossible to remove them out of the house after 

 the growth is made ; and in order to remedy this, the top 

 sashes, as well as those at the sides of the house, must be

 remain long enough to do any injury.' The white scale 

 sometimes makes its appearance, and this must be at once 

 washed ofi' with warm water and soft, soap. We have selected

C. alba plena (the old Double White). — Flowers large, of 

 perfect form, petals round and symmetrical ; pure white ; 

 one of the most useful varieties for general purposes.
