BROAD ROUND-HEADED TREES.

principally employed in ornamental scenery. As we go 

 on, we may point out their most suitable and effective 

 positions in the park and pleasnre-gronnds. 



The first division consists of trees with broad, round 

 heads ; the second, of those with a spiry, conical, or 

 pyramidal configuration ; the third, of those with upright 

 or oblongated forms ; and the fourth, of those with weep- 

 ing 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 deciduous 

 kinds, the sycamore, the American plane, the common 

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

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

 chestnut, beech, birch, hornbeam, and others. 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 

 [Cupressus macrocarpd) . 



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. 



The Ash has 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 it 

 not continue so short a time in leaf. It grows well in 

 exposed situations.
