THE BEST SHRUBS TO PLANT 119 



aquifolia, Berberis stenophylla, Cytisus sco- 

 parius, Ledum pa'lustre, and three species of 

 Spirea (S. Lindleyana, S. Douglasii, and S. 

 fruticosa). But the most remarkable instance 

 is that of the Bearberry (Arctostyphalos Uva 

 ursi), which positively seems to revel in the 

 smoke-laden atmosphere of these gardens, 

 and has increased from a tiny plant to a bold 

 spreading clump some 4 ft. across, with 

 foliage of the healthiest description. It is 

 certainly strange why a shrub that is native 

 of high mountain districts where the air is of 

 the purest description can even subsist, let 

 alone positively thrive, near sea-level and in 

 the foulest of town atmospheres.
