INJURY SUSTAINED BY WALL TREES. 
floor being laid under the trellis,, which would much increase the re¬ 
flection. If it is needful to protect the crop from frost, the trees are 
easily covered with mats, or by a roll of canvass being laid over them 
at nights, particularly during the blossom season. 
The most convenient dimensions for the trellis work, will, I think, 
be found as follows :—The border will be about sixteen feet across,— 
the trees should be planted one foot from the walk,—the trellis should 
be one foot high in front, four feet high at the back, and eight feet 
wide, making in the whole nine feet of the width of the border occu¬ 
pied, the remaining seven feet, betwixt the back of the trellis and the 
wall, should be left unoccupied for the convenience of being able to 
prune and dress or gather fruit from the trees occupying the wall. I 
must here observe, however, that neither peaches nor nectarines will 
answer on the trellis, but all the fine varieties of plums, cherries, and 
apples thrive admirably, and have a very superior appearance to 
common vegetables, which with equal facility might be grown on 
quarters, with a little contrivance, or under board or reed fences.

The plan here noticed by Mr. Bristow certainly merits attention, 
the ground by this mode being much more advantageously occupied 
than it could possibly be by the choicest vegetables, but it could not 
in all cases be adopted, particularly where quantity of land is an ob¬ 
ject, or where fruit is not so much in requisition as vegetables. But 
the principle is good, and it may be followed up where it suits the 
convenience of parties. If the trees on the trellis be kept thin of 
wood, no evil can arise from the ground being heavily shaded, but 
on the contrary in dry seasons some advantage may be the conse¬ 
quence. Twelve months previous to our receiving the above paper, 
which is now nearly a year ago, we had tried a similar mode at 
Chatsworth, of occupying a fruit border on a south aspect eight feet 
wide, only with this difference, that the trees instead of being planted 
at the front of the trellis and trained upwards, were planted at the 
back (fig. 30) and trained downwards. The advantage of this mode
