done very much better. Evergreen ; South Spain, 

 1839 ; height 60 to 80 feet. 



Acer Pseudo-plat anus, Mock Plane Tree, Syca- 

 more. This tree is largely planted on the York- 

 shire cliffs, and is one of the hardiest and most 

 useful for the first line of exposure, especially 

 where the soil is light, dry, and deep. It will 

 succeed in almost any soil where it is open and 

 free, but does not answer so well where its roots 

 are near the clay. As it is of early growth its 

 young shoots are often much injured by gales off 

 the sea in spring, but the tree soon recovers, and 

 thick, stunted, bushy top growth is the result. 

 As the main object when planting trees in such 

 positions is to secure an efficient break to the 

 winds, so as to afford shelter beyond, it answers 

 this purpose admirably. Deciduous ; mountains of 

 Central Europe and Western Asia. Introduced 

 into England during the fifteenth century. 



^ELsculus Hippocastamim, Common Horse 

 Chestnut. A well-known hardy tree, thrives best 

 in good, rich, deep soil. It grows rapidly, when 

 sheltered, near the sea. As it is of early growth 

 in spring its young leaves are often destroyed 

 when exposed to north-east winds. Deciduous ; 

 indigenous to the mountains of Greece ; Asia, 

 1629. There are several ornamental garden 

 varieties producing red and pale coloured flowers. 



Alder. See Alnus.
