TERRACE WALLS 



delicate light green tint, held well erect ; and that it 

 also bears showy crimson flowers. The variegated 

 periwinkles will give perpetual beauty to the rock 

 or brick surfaces, and the creeping euonymus will 

 display its glossy leaves, with green and white 

 variegations, all the year round. There are numer- 

 ous other desirables and dependables, but these will 

 guide in the choice, and give pleasing variety. They 

 will flourish with the usual methods of wall laying, 

 being tucked in crevices after the wall is finished; 

 but, as has been said, it is better to provide for them 

 in the building of the wall. 



As the stones are laid in place, set the roots of the 

 little plants at the desired intervals well back in the 

 crevices, with a good sprinkling of soil over them. 

 They should be set in the right direction to reach 

 back into the moist earth behind the wall for susten- 

 ance. Eich earth and gritty sand, well packed back 

 of the wall, will be of lasting benefit to these plants, 

 and with such provision for their development they 

 will be sure of good drainage and moisture among 

 the rocks. When both large and small stones are 

 used in dry walls the irregular spaces give oppor- 

 tunity for a great variety of plants that will keep the 

 wall rarely beautiful from early spring to late 

 autumn, with evergreen trailers clothing the rocks 

 during the winter.
