produces its big white flowers in profusion. 

 The Scillas all do well, and particularly so the 

 species of Allium, while Narcissus are not to 

 be despised. Out of a large number of Al- 

 pine and rock plants that I have experimented 

 with, the above are the most suitable and re- 

 liable for town gardening, especially in 

 London. There are others, however, that do 

 well for a few years, but gradually become less 

 in size and floriferousness and ultimately die 

 out altogether. By procuring strong, well- 

 rooted specimens and planting these in suit- 

 able soil, half the victory in getting rock and 

 Alpine plants to become established in town 

 and city gardens is accomplished.
