back streets and slums of London may be seen well-grown 

 specimens, which clearly demonstrate how well suited it is 

 for withstanding smoke and dust. 



The Sugar Maple (Acer saccharinum) is a handsome, 

 hardy, and fast-growing tree of moderate dimensions, and 

 one that can justly claim a place in any list of town 

 trees. It will not succeed where constantly subjected to 

 smoke and fumes, but planted in the suburban districts it 

 soon forms a really handsome and distinct tree. 



Sophora japonica is worthy of recommendation as a tree 

 that is admirably suited for planting in towns. It is of large 

 and rapid growth, with elegant dark green pinnate leaves. 

 Being a native of China and Japan, it may not be perfectly 

 hardy in the colder portions of the British Isles, but it 

 succeeds well in southern England and Ireland, and it thrives 

 admirably in the most smoke-infested parts of London. 



Thorns of various kinds succeed in town parks and 

 gardens, but they are not to be recommended for the most 

 smoky and confined localities. In Glasgow, however, I have 

 noticed how well suited for planting in the squares and 

 public gardens many forms of the thorn are ; indeed, even in 

 London, and where smoke and dust are by no means 

 wanting, they gladden the eye with their wealth of flowers 

 and bright green leaves. The single and double scarlet 

 would seem to be best adapted for withstanding soot and 

 smoke ; and these may not infrequently be seen of large size 

 and in perfect health. 



The Tansy-leaved Thorn (Crataegus tanacetifolia) is 

 another excellent member of the family for town-planting. 

 A noble example may be seen near the entrance to the 

 Glasgow Botanic Garden. 



The English Yew {Taxus baccata) can hardly be 

 recommended as a suitable tree for smoky localities, although 

 in suburban districts it grows freely, and there forms a dense, 

 healthy, dark green mass. From this it must not, however, 

 be inferred that the yew cannot survive in smoky towns, for 

 it grows freely wherever it is not subjected to an inordinate 

 amount of atmospheric impurities. Soil of fairly good quality 

 should be used when planting the yew, particularly where 

 the surroundings are unfavourable.
