glaring contrast to the too oft-repeated yellowish hue of the 

 London plane. But this is not the only place in town where 

 during the past summer we have been charmed with the 

 delightful freshness of the tree in question, for in many of 

 the most smoke- infested quarters, and where even the 

 famous plane looks sear and sickly, the weeping ash forms a 

 noble specimen of the most refreshing green. There are 

 many forms of the so-called weeping ash, but that of dwarf 

 is most to be recommended for doing battle with the 

 deleterious effects of a city atmosphere. It likewise with- 

 stands long-continued heat and drought in a most remarkable 

 manner, in that respect being only equalled by the false 

 acacia and Indian bean — two of the very best trees for dry 

 and warm summers. 



The Black Italian Poplar (Populus monilifera). — 

 Next to the plane amongst forest trees, I consider the black 

 Italian poplar to be the most valuable for planting in smoky 

 towns. As a proof of this, there are to be seen numerous 

 fine specimens of this tree in a flourishing condition, and 

 clothed with the most healthy foliage, in some of our largest 

 cities — to wit, London, Glasgow and Liverpool. The black 

 Italian poplar may be somewhat stiff in outline, but there is, 

 nevertheless, an air of grace about it that is wanting in 

 any other tree I can bring to mind. It is a tree of readiest 

 culture, while, as to its rate of growth, a specimen of 

 100 feet in height has attained to that size in less than sixty 

 years. The wood, unless for a few special purposes, such as 

 cart bottoms, brakes, &c, is not of great value ; but the 

 tree is, nevertheless, a profitable timber-producer when 

 grown in suitable soils. 



The Canadian Poplar (P. canadensis) and its variety, 

 P. c. nova, are excellent trees for planting is smoky localities. 

 The former succeeds admirably in the very centre of 

 Sheffield, in the old Parish Churchard, where for hundreds 

 of yards away not a particle of living vegetation is to be 

 seen. The variety nova is a very superior tree for street- 

 planting, it being far more ornamental and of more rapid 

 growth than the black Italian poplar, and equally reliable 

 for retaining a healthy and flourishing condition under the 

 adverse circumstances connected with a town atmosphere. 

 How well it succeeds may be seen in the beautiful avenue
