The stem (see Fig. 2), whichruns fairly straight to the top of the tree, is coatedwith thin peeling bark, with horizontal lenticels, and ofa very lighi colour. Near the base, and in placeshigher up, are dark patches of thick corky bark, whichspread as the tree gets older. The root system is weakand shallow, the leaves are simple, broad at the baseand pointed at the end. The flowers are catkins, the maleones pendant, the female ones erect. The fruit, also incatkin form, remains hanging on the tree for months, 92 REES AND TKEE Dl^AVVLNO :#- i., \m w^. TREES AND TREE DRAWtNG. 93 after its ripening in the late autumn. The wholeappearance of the Birch is light and graceful, both inwinter and summer. The drawing given is of a tree inthe fullest of its summer foliage, when the leaves formpendant masses ; but perhaps when the leaves turnyellow, and are sparsely scattered on the brown hangingtwigs, and the fruit catkins are seen amongst them,then is the trees most exquisite period. The Birch has several varieties, the differences beingmainly in the browner or whiter colour of the bark, ofthe angle of the leaves, whether held out horizontally orhanging down, and the course of the branches, whetherrunning upwards as they start from the stem, or whetherthe ends droop, making it a weeping tree. This tree is often much infested with the diseaseknown as witches brooms, more so, in fact, thanany other of our trees, though it is common on theWild Cherry and the Hornbeam. The Birch is the typical light-demanding tree. Itg
