36 Soot as Manure. Six quarts of soot to a hogshead of water, 
is stated, in the Gardener’s Magazine, vol. 2, to make a liquid 
manure of excellent properties. To plants in pots, to pines, 
and to common vegetables, it is said to have proved an admi- 
rable stimulus. 
37 Protection of Wall Fruit Trees. It is well known, from 
observation, that copings of about eighteen inches w ide, on gar- 
den walls, preserve a temperature on its surface, at times, several 
degrees above that of the surrounding atmosphere. It obstructs 
the ascent of heat and the descent of cold ; and by the protec- 
tion which it affords the wall from rain, much evaporation is 
avoided, which tends so rapidly to carry off its imbibed heat. 
These copings, however, are expensive, of heavy appearance, 
and prevent the access of showers when they would be benefi- 
cial. This has been somewhat obviated by having it made of 
boards, with hinges, to admit its being turned back, occasion- 
ally, on the top of the wall. But, further to meet some of these 
objections, Mr. Gorrie, of Annat Gardens, uses a living vegeta- 
ble coping, which is both useful and ornamental. In the Gar- 
dener’s Magazine he says “ I have long observed the advan- 
tage to peach trees of a coping formed by the ample leaves of 
the fig, compared with others not under such protection. This, 
some years since, induced me to turn my attention in quest of 
some ornamental plant which might be trained on a light trellis 
from the ground upward to the top of the wall, at right angles 
from the wall, and occupying the same breadth across the bor- 
der as the trellised projection at the top; the supporting trellises 
to stand at the extremities of the shoots of peach and other 
tender fruit trees, or at equal distances from their stems. The 
plant I have fixed on, and planted for that purpose, is the 
double-flowered Ayrshire rose. The leaves of this rose tree 
expand early in spring, when their aid is wanted in exposed 
situations ; and, where plants of it are trained on side trellises, 
they contribute to produce a calm serenity along the face of 
the wall, while those on the projecting trellis become sufficient- 
ly close for repelling terrestrial radiated heat, and throwing it 
back on the wall and border : thus, in both instances, contri- 
buting towards the protection of the tender blossom, and the 
setting and maturing of the fruit.” Various methods of giving 
temporary protection will, shortly, be noticed.
