138 PARKS AND PLEASUEE-GEOHNDS. 



then to refer to a few of the kinds principally em- 

 ployed in ornamental scenery. As we go on, we may 

 point out their most suitable and efi'ective positions in 

 the park and pleasure-grounds. 



The first division consists of trees with broad, 

 round heads ; the second^ of those with a spiry, con- 

 ical, or pyramidal configuration; the tliird, of those 

 with upright or oblongated forms; and i\i& fourtli, of 

 those with weeping or pendulous branches. The 

 reader is reminded that these forms are given merely 

 as approximations : he is not to attach to them the 

 precision of geometrical figures. 



(1.) Broad^ Round-headed Trees. — Of the decidu- 

 ous kinds, the sycamore, the American plane, the com- 

 mon oak, the Turkey oak, the small-leaved and Scotch 

 elms, the ash, the tulip-tree, walnut, horse-chestnut, 

 Spanish chestnut, beech, birch, hornbeam, and otherSi 

 The evergreens of this division are few, viz : evergreen 

 oak, Luccomb oak, yew, cedar of Lebanon, cedar of 

 Mount Atlas, deodar or Indian cedar, and Lambert's 

 Cypress. (Cwpressus macrocarpa.) 



The Sycamore is a large, rounded tree, fully branched 

 and of massive foliage. Its formal outline, and its 

 close, broad attire of leaves, are well suited to produce 

 depth of shade. It has also the property of retaining 

 its form in exposed situations, and in such positions it 

 imparts to a clump or group a more decided outline 

 than can be given by any other hard-wood tree. 

 Ar The Ash lias a light foliage, and a graceful, airy 

 appearance, particularly when the branches assume a 

 pendent habit. It generally displays much of the in- 

 ternal arrangement of its boughs, which is often pic- 

 turesque in old age. It would be a fine lawn tree did
