will answer equally well, and even better, for the grass. The 

 soil from the bottoms of the walks, when good, can also be used 

 for the part to be planted. 



The trees and shrubs which will be required are indicated in 

 the following lists ; and they are all such as may be purchased in 

 the London nurseries at moderate prices, and all of the most or- 

 namental kinds, not one being admitted which is a mere timber 

 tree or fruit tree, or which is purely of botanical interest. 



The first list (I.) consists of evergreens; and they are distributed 

 over the whole garden in such a manner as to prevent the eyes of 

 the persons on the walks, both in summer and winter, from seeing 

 more than a certain portion of the ground at one time. At the 

 east and west ends of the ground there are rows of evergreens 

 and semi-evergreens of comparatively tall growth, for the purpose 

 of shutting out the houses of the town. All the other trees are of 

 low growth ; and, with two or three exceptions, do not ordinarily 

 exceed the height of from 1 2 ft. to 20 ft. 



The next list (II.) is of deciduous or flowering trees, and tall 

 shrubs, with some evergreens, all about the same height as those 

 in List I. These are to be distributed over the ground as indi- 

 cated in the plan by the numbers preceding the names. 



The next list (III.) is of deciduous flowering shrubs, and some 

 evergreens, the distribution of which may be left to the planter, 

 with this single direction, that the species of each genus must 

 be kept adjoining each other. 



The succeeding list (IV.) is of climbing, creeping, and trailing 

 plants. These it is proposed to plant along an arcade of trellis- 

 work, which should be commenced at each entrance of the tun- 

 nel, and carried on to the length of 50 ft., at each end, over the 

 walk. The trellis-work, where it terminates, should be quite 

 light and open, and, in short, little more than arches of iron wire, 

 crossing the road at about 6 ft. apart. This distance between the 

 arches should gradually diminish, till, at the mouth of the tunnel, 

 the last arch should not be more than 3 ft. from the one preceding 

 it. Each arch should consist of three iron wires; each of about 

 half an inch in diameter, joined together by horizontal pieces, and 

 their lower ends leaded into blocks of stone. Along the summit 

 of the arches, one rod may connect the whole; but there ought 

 to be no connexion along the sides, or at the bottom. The same 

 rod may be continued along close, under the roof of the tunnel 

 for hanging coloured lamps on, upon extraordinary occasions, so 

 as to illuminate both the tunnel and the arcade. 



It is very desirable to form an arcade of this sort as an ap- 

 proach to a tunnel ; because, to a stranger, and in the summer 

 time more especially, the transition from the glow of a mid- 

 day sun to the gloom of the tunnel would be too sudden. At 

 the same time, the tunnel will be only comparatively dark, as it
