WALLS, ESPALIER-RAILS, AND TRELLIS-WORK. 



for supporting shrubs which come early into flower, such as the 

 Pyrus japonica, Wistaria sinensis, China and other climbing roses, &c., 

 they may be easily protected by a moveable coping of boards, like an 

 inverted gutter, which can be dropped on or taken off in a very few 

 minutes. In order to economize space in small gardens, Mr. Alexander 

 Forsyth proposes to cover the walks with trellis-work for the sup- 

 port of fruit-trees. " Every species of hardy fruit-bearing tree and 

 shrub," he says, " may be trained on curvilinear trellises, as in 

 figs. 120 and 121, over the walks and thoroughfares of the garden;

which walks, when once properly drained, paved, and trellised with 

 cast-iron arches and wire rods, will remain cost free, painting ex- 

 cepted, for twenty years ; at the end of which term, independently of 

 the increase of fruit, and of the grateful shade and pleasing promenade 

 that they will afford, they will be found cheaper than the walks made 

 of gravel, in the same way that a slated roof is far cheaper in the 

 long run than one thatched. Besides the difference in daily comfort 

 and annual expenditure in walks paved with slate, slabs, or flagstone, 

 at all seasons clean, and capable of being traversed by the foot or the 

 wheelbarrow alike in frost and in thaw, there will be no more danger of 

 dessert strawberries or garnishing parsley, when grown as edgings, 

 being mingled with the coal-ashes in the walks ; no more cleaning 

 and rolling of gravel ; and no planting and clipping of box." Fig. 

 122 shows the plan of the paving and pillars at the intersections 

 of the walks, with the small footpaths outside, for conducting the
