priucipallv employed in ornamental sceneiy. As we go 

 on^ we may point out theii' most suitable and effective 

 positions in tlie park and pleasiu'e-gi'omids. 



The first division consists of trees with broad^ roimd 

 heads; the second, of those with a spiiy, conical^ or 

 pyi'amidal configiu-ation ; 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 figiu^es. 



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

 kinds_, the sycamore^ the American plane^ the common 

 oak^ the Tm-key oak^ the small-leaved and Scotch elms, 

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

 chestnut, beech, bii'ch, hornbeam, and others. The 

 evergreens of this dirision are few, riz., evergreen oak, 

 Luccomb oak, yew, cedar of Lebanon, cedar of ]Moimt 

 Atlas, deodar or Indian cedar, and Lambeit^s cypress 

 [Cupressus macrocarpa). 



The Sycamore is a large, roimded tree, fiilly branched, 

 and of massive foHage. 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 ti'ee. 



The Ash has a light foliage, and a gi^acefiil, airy 

 appearance, paiiicularly when the branches assiune a 

 pendent habit. It generally displays much of the m- 

 temal aiTangement of its boughs, which is often 23ic- 

 turesque in old age. It wordd be a fine lawn ti'ce did it 

 not continue so short a time in leaf. It gi'ows well m 

 exposed situations.
