Nearly all the plants formerly in- i 

 eluded in this genns have been ' 

 removed to Clerode'ndrum, and it I 

 now contains only two species, one ■ 

 a stove shrub with white flowers, | 

 from the West Indies ; and the j 

 other a half-hardy tree, with purple 

 flowers, from Nepal. I 



WACHEXDO'RFIA. — Ecemo- \ 

 doracece. — Bulbous and tuber- ' 

 ous-rooted plants with large panicles '■ 

 of very showy flowers, Avhich are 

 generally yellow. These plants have '■ 

 rhizomas or under-ground stems, in \ 

 the scales of which, in some of the J 

 species, little bulbs form, which, if | 

 removed and planted, become dis- ! 

 tinct plants. These are the bulbous ' 

 kinds. The others have the same ' 

 kind of rhizoma or fleshy under- j 

 ground stem, but no bulbs form in , 

 it. All the kinds are nearly hardy, | 

 and they will thrive in the open '■ 

 ground, provided the situation be 

 tolerably dry, without its being ! 

 necessary to take up their roots j 

 during winter. 



"Wahlexbe'rgia. — Camjjanu- 

 lacecP: — Perennial and annual 

 plants, formerly considered as be- 

 longing to Campanula, and of which 

 Campanula c/randifldra is the type. 

 They should all be grown in sandy 

 loam, and they are propagated by 

 seeds, or by division of the roots. 



Walks may be considered with 

 reference to their direction, their 

 construction, and their management. 

 In a small garden, the direction of 

 the main walks .should generally be 

 governed by the boundary lines ; 

 and hence, in a jjlot of ground 

 which is square or oblong, the walks 

 .should be straight and rectangular ; 

 the object in .such a case being to 

 produce the beauties of regularity 

 and symmetry. On the other hand, 

 when the boundaries of a garden 



are irregular, the surrounding walk 

 may be irregular also ; the object 

 in this irregularity being to create 

 a variety by contrast in the direc- 

 tion. When a garden bounded by 

 straight lines is so large as to con- 

 tain an acre or two, and the whole 

 of the interior is to be laid out as 

 a pleasure-ground, then the walks 

 may be varied in direction ; the 

 boundary being concealed by trees 

 and .shrubs, or by artificial undula- 

 tions of the soil. In general, it 

 may be laid down as a principle, 

 that all walks should be straight 

 when there is no obvious reason 

 why they should be otherwise ; and 

 hence, in the case of all winding 

 walks, if there is not a natural and 

 apparently unavoidable reason for 

 their deviating from the straight 

 line, an artificial reason ought to be 

 created. This may always be done 

 even on a flat sui'face, by the posi- 

 tion of trees and shrubs ; or when 

 there is the slightest inclination to 

 inequality of surface, the same suffi- 

 cient reason may be created by 

 heightening these inequalities. When 

 a ■winding walk bends to the right, 

 the trees and shrubs ought to be 

 chiefly conspicuous on the left side, 

 and on the contrary ; and the same 

 rule is applicable to the natural 

 or artificial inequalities. When a 

 walk is made perfectly straight, 

 the surface of the ground ought to 

 be perfectly even for some feet in 

 width on each side of the walk, 

 excepting in some few cases, such as 

 a straight terrace walk along a 

 regular uniform slope, in which 

 case the ground on one side of the 

 walk will rise regularly, and on the 

 other side will fall regularly. All 

 straight walks should lead to some 

 conspicuous object at the farther 

 end of the walk, and facing it, so 

 as to appear to belong to it ; and 

 this object should be seen the
