The Vine (Vitis vinifera) must not be omitted from any list of 
town climbers, for it bears exposure to soot, smoke, dust, and heat 
in a surprising manner. In many towns it may be seen doing 
well, and covering large areas of wall with its large finely- 
divided leaves. There are several cut-leaved forms, one or 
two of which are, perhaps, more ornamental than the typical 
plant. 
Several other climbing wall-plants do well in large towns where 
excessive quantities of smoke are absent, but the above may be 
relied upon as those that are best suited ‘for planting where the 
atmosphere is constantly vitiated with impurities. 
ConIFEROUS TREES. 
Few of these, if any, succeed in a satisfactory way when 
constantly subjected to the impurities of a town atmosphere. 
Where the conditions are favourable, the Austrian pine (Pius 
Austriaca), Thujopsis dolabrata, deciduous cypress (Laxodium 
distichum), and Lawson’s cypress (Cupressus Lawsonit) do fairly 
well, but they are not to be recommended for general town 
planting. Letinospora plumosa aurea stood for five years in one 
of the most smoke-infested districts of Glasgow, and looked 
almost as well as it did when brought from the country. 
Oruer PLANTS. 
Yuccas of various species are to be highly recommended for 
planting, even in very smoky and confined districts. They grow 
with great freedom in many of the London gardens, as also in 
Glasgow, Liverpool, and Manchester. Irises, notably J. Ger- 
manica, do well even in very smoky and confined districts, as they 
have a marvellous recuperative power after being subjected to the 
heat, dust, and general impurities of a town atmosphere. Auriculas 
and border carnations also do fairly well, but they will not stand 
constant smoke and soot; and the same may be said of various 
species of hellebore, Virginian stock, Hranthis hyemalis, and 
chrysanthemums, 
Much may be done to keep plants fresh and healthy by free 
use of the watering-pot, syringe, and hose, aud also by carefully 
looking after insect pests, and stamping them out as they appear.
