whatever material, of which the parts otherwise bare might not he 

 made ornamental with flowers. I do not suggest that such things 

 should supersede climbing Roses and wall-fruit, but how often we 

 see bare walls on which nothing is grown at all ! The capabilities 

 of rough stone walls for growing mountain plants are very great. 

 Falls of Aubrietia and Iberis, groups of Saxifrage, and similar 

 subjects may make many a corner gay instead of bare. Some very 

 pretty things I grow on walls which have defied all my attempts 

 to cultivate them elsewhere. I may specify Lychnis Lagasccs, a 

 fragile evergreen plant of shrubby growth, easily multiplied by 

 seed, which alternate snows and thaws generally crush up, but 

 in this way it continues to thrive, and is covered during early 

 summer with crimson flowers. 



I have now come to the end of my subject, and only add 

 that I have made a careful selection of one hundred and fifty 

 or so alpine plants suited for English rockeries in a list given as- 

 an appendix, from which all coarse growers are excluded.
