formed into grass-ground, either before or after planting the trees; 
and in planting the groves, it is most eligible to arrange the trees in 
lines, in some places straight rows, others in gentle bendings, or 
easy sweeps, having the rows at some considerable distance, that 
the trees may have full scope to display their branchy heads regu- 
larly around; and in some places may have close groves to form a 
perfect shade. 
As to avenues and walks of trees, they may be formed either 
entirely of deciduous trees, or of cver-greens; but the deciduous 
kinds are in most estimation for this purpose: however, avenues 
and grass walks, planted with fine ever-green trees, make a beauti- 
ful appearance, and will always command admiration. In both sorts, 
the trees are most commonly disposed in rows, one on each side of 
the avenue; though sometimes grand walks of trees may be both 
in single straight lines, and in double rows, to exhibit the greater 
variety; planting the trees generally, both in avenues and walks, at 
proper distances, to have full scope to branch out regularly around 
and display their beautiful heads and loliage. 
Thickets may be composed of all sons of hardy deciduous trees, 
planted close and promiscuously, and with various common shrubs 
interspersed between them, as underwood, to make them more or 
less close in different parts, as the designer may think proper. 
They may also be of ever-green trees, particularly of the pine 
and fir kinds, interspersed with various low-growing ever-green 
shrubs. 
In some open spaces of grass-ground, such as spacious open 
lawns, or other considerable open fields, &c. you should dispose 
some of the most beautiful trees and elegant shrubs detached, both 
separately as standards or single objects; and in groups or assem- 
blages, from two or three, to five, ten, or more in different groups 
or clumps; some irregularly, others in curves, straight lines, &c. 
for variety; arranging both single standards, and groups, a consider- 
able distance asunder, not to obstruct the prospect, and at such va- 
ried distances as if they had grown there by chance. 
It very frequently happens, that on the spot or tract, which is 
designed for a pleasure ground, are found large stately trees of con- 
siderable standing, properly situated to be introduced into the de- 
sign; and sometimes numbers in suitable assemblages, for consti- 
tuting groves, or thickets, and some for single standing groups or 
clumps. Sec. which will prove of considerable advantage; these 
should be preserved with the utmost care, as it would require many 
years to form the like with young plantations; and although the trees 
should stand ever so close, irregular, or straggling, with proper ad- 
dress in thinning and regulating them where necessary, they may be 
made to become beautifully ornamental to the place, and to prevent 
a considerable expense. 
In some spacious pleasure-grounds various light ornamental 
buildings and erections arc introduced, as ornaments to particular 
departments; such as temples, bowers, banqueting houses, alcoves, 
grottos, rural seats, cottages, foyntaios, obelisks, statues, and other
