parts of a town, the lime has certainly few equals, its general 

 contour and the pleasing shade it affords being points of 

 special recommendation. 



The Sycamore (Acer Pseudo-platanus). This tree may 

 be classed as amongst the most useful for planting in smoky 

 towns. 



In Warrington, where the noxious emanations from 

 alkali and other chemical works are most disastrous in their 

 effects on vegetation, the sycamore is one of the few trees 

 that grow satisfactorily. Being a rapid and strong grower, 

 it is thus seen to be, for a certain time at least, unaffected 

 by its inimical surroundings. The variegated variety 

 would seem from recent experiments to be preferable, and 

 better adapted for smoky localities than the normal form. 



The Weeping Ash (Fraxinus excelsior pendula) would 

 seem to be superior to the common ash for planting in towns. 

 It thrives satisfactorily in many of our largest centres of 

 industry to wit, London, Liverpool, Glasgow and Man- 

 chester. 



The Horse Chestnut (JEsculus Hippocastanum) may 

 be seen in a fairly satisfactory way in many town parks, 

 but only where it is not exposed to smoke and soot to any 

 great extent. In confined spaces both it and the English 

 Elm (Ulmus campeslris) soon show signs of distress, the 

 points of the branches gradually becoming unhealthy, 

 and the trees dying off prematurely. Taking everything 

 into consideration, neither of these trees can be recom- 

 mended for planting in smoky districts. The Birch, 

 Walnut, Hornbeam, and one or two kinds of Willow 

 will succeed in the less smoky parts of a town ; but they 

 are not to be recommended for planting where the air is 

 constantly impregnated with soot and dust. 



The Mountain Ash, or Rowan Tree (Pyrus Aucuparia) 

 and Bird Cherry (Cerasus Padus) are both good town 

 trees, and excellent examples of both may be seen in the 

 back streets and slums of London. 



Sophora japonica is well 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
