WOODS AND PLANTATIONS. 381 



The Ontario Poplar (Populus candicans, Aitchison). This is very like 

 the balsam poplar ; it is also a native of North America, and grows to a 

 height of from fifty to sixty feet in this country. The buds in spring 

 give out a pleasant balsamic odour, and when the leaves come out they 

 have a yellowish colour. The leaves are large. 



The Aspen Poplar (Populus tremula). This is not a good timber-tree, 

 but it is ornamental, and has a fine effect, from the trembling motion of 

 its leaves. It makes very good copsewood. 



TJie White Poplar (Populus alba, Linnaeus) is a native of Europe, 

 and is a fast grower, with a straight upright stem. It attains a height 

 of fully eighty feet in this country, and makes a fine contrast amongst 

 other trees, from the whiteness of its leaves. The timber is white and 

 soft. 



The Black Poplar (Populus nigra). This is a native of Europe and 

 Africa. It is a rapid-growing tree, and attains large dimensions in this 

 country. It is used for the same purposes as the black Italian poplar. 



The Grey Poplar (Populus canescens). In good situations this tree 

 comes to a large size in this country. Its timber is used for cooper- 

 work and machinery purposes. It is very hardy and ornamental. When 

 grown as coppice, it pays well, and is used for crate-wood and hampers, 

 and is a fast grower. 



The Service- Tree (Pyrus sorbus). This is a native of Europe. It is 

 not planted in this country with the view of producing timber, but for 

 ornament. It grows to a height of from forty to sixty feet. The timber 

 is hard, and takes a fine polish. 



The Sloe or Mack Thorn (Prunus spinosa, Linnaeus). This is a native 

 tree of small size and of a coarse rambling nature, but useful as under- 

 wood. 



The Gean or Wild CJierry (Cerasus sylvestris) is a native of this country. 

 The timber is close grained and firm. It is hardy, and grown for 

 ornament chiefly. 



The Common Hazel (Corylus avellana, Linnaeus). This assumes more 

 the form of a bush than a tree in this country. It is indigenous to 

 Europe, and very common as copsewood, and it is profitable to grow as 

 such, being in much request for the making of crates, hampers, broom- 

 handles, &c. 



The Hornbeam (Carpinus betulus). This is a native of Britain and 

 Europe, and when cultivated in a good soil attains a height of from 

 fifty to sixty feet. The timber is close grained and hard. It makes a 

 good hedge plant. It resembles the beech, but may be distinguished 

 from it by the feathery appearance of the leayes. 



The Laburnum (Cytisus Laburnum). This is a native of Europe, and
